Includes disabling PBMS (per Paul's recommendation) and test file fixes.
Signed-off-by: Kristian Nielsen <knielsen@knielsen-hq.org>

 - Disable PBMS in MariaDB (as per recommendation of Paul).
 - Add missing *-master.opt files to make testsuite work on case-sensitive file systems.
 - Result file updates.

Solaris build scripts under BUILD/ were changed, but Makefile.am was not updated to reflect
the new set of file names.

Added build scripts for 32 bit x86 architecture on Solaris.
Renamed some scripts for consistency.
Changed to dynamic linking of libgcc.


BUILD/compile-solaris-amd64:
  Changed to dynamic linking of libgcc.
  
  The -static-libgcc was a legacy of the original build scripts. -R
  (analogous to -L link time search path) is a Solaris mechanism to
  ensure a needed lib directory is searched at runtime.
  
  In Solaris 10, gcc comes bundled, under /usr/sfw, allowing to use it without
  creating dependency problems. This allows eg. benefiting from ordinary system
  patch maintenance.

Added MY_CS_NONASCII marker for character sets that are not compatible with latin1 for characters 0x00-0x7f
This allows us to skip and speed up some very common character converts that MySQL is doing when sending data to the client
and this gives us a nice speed increase for most queries that uses only characters in the range 0x00-0x7f.

This code is based on Alexander Barkov's code that he has done in MySQL 6.0


include/m_ctype.h:
  Added MY_CS_NONASCII marker
libmysqld/lib_sql.cc:
  Added function net_store_data(...) that takes to and from CHARSET_INFO * as arguments
mysys/charset.c:
  Mark character sets with MY_CS_NONASCII
scripts/mysql_install_db.sh:
  Fixed messages to refer to MariaDB instead of MySQL
sql/protocol.cc:
  Added function net_store_data(...) that takes to and from CHARSET_INFO * as arguments
sql/protocol.h:
  Added function net_store_data(...) that takes to and from CHARSET_INFO * as arguments
sql/sql_string.cc:
  Quicker copy of strings with no characters above 0x7f
strings/conf_to_src.c:
  Added printing of MY_CS_NONASCII
strings/ctype-extra.c:
  Mark incompatible character sets with MY_CS_NONASCII
  Removed duplicated character set geostd
strings/ctype-sjis.c:
  Mark incompatible character sets with MY_CS_NONASCII
strings/ctype-uca.c:
  Mark incompatible character sets with MY_CS_NONASCII
strings/ctype-ucs2.c:
  Mark incompatible character sets with MY_CS_NONASCII
strings/ctype-utf8.c:
  Mark incompatible character sets with MY_CS_NONASCII
strings/ctype.c:
  Added function to check if character set is compatible with latin1 in ranges 0x00-0x7f

Changed default thread stack to 288K to get better memory missalignment between stacks of different threads (should speed up things) and to get a bit extra safety.
In maria_open(), don't allocate big arrays on stack as this may lead to stack overflow.
This fixes a valgrind warning detected by buildbot

include/my_pthread.h:
  Changed default thread stack to 288K to get better memory missalignment between stacks of different threads (should speed up things) and to get a bit extra safety.
storage/maria/ma_open.c:
  In maria_open(), don't allocate big arrays on stack as this may lead to stack overflow.

- Added a handler call (prepare_index_scan()) to inform storage engines that an index scan is about to take place.
- Extended the maximun key parts for an index from 16 to 32
- Extended MyISAM and Maria engines to support up to 32 parts

Added checks for return value from ha_index_init()



include/my_handler.h:
  Extended number of key parts for MyISAM and Maria from 16 to 32
include/my_pthread.h:
  Ensure we always have 256M of stack.
  (Required to be able to handle the current number of keys and key parts in MyISAM)
mysql-test/r/create.result:
  Extended to test for 32 key parts
mysql-test/r/myisam.result:
  Test that we can create 32 but not 33 key parts
mysql-test/r/ps_1general.result:
  Length of ref is now 2048 as we can have more key parts
mysql-test/r/ps_2myisam.result:
  Length of ref is now 2048 as we can have more key parts
mysql-test/r/ps_3innodb.result:
  Length of ref is now 2048 as we can have more key parts
mysql-test/r/ps_4heap.result:
  Length of ref is now 2048 as we can have more key parts
mysql-test/r/ps_5merge.result:
  Length of ref is now 2048 as we can have more key parts
mysql-test/suite/maria/r/maria.result:
  Max key length is now 1208 bytes
mysql-test/suite/maria/r/maria3.result:
  Max key length is now 1208 bytes
mysql-test/suite/maria/r/ps_maria.result:

mysql-test/t/create.test:
  Extended to test for 32 key parts
mysql-test/t/myisam.test:
  Test that we can create 32 but not 33 key parts
sql/handler.cc:
  Check return value from ha_index_init()
sql/handler.h:
  Added a handler call (prepare_index_scan()) to inform storage engines that an index scan is about to take place.
sql/sql_select.cc:
  Checks all return values from ha_index_init()
  Call prepare_index_scan()) to inform storage engines that an index scan is about to take place.
  Fixed indentation
sql/table.cc:
  Fixed wrong types for key_length (rest of code assumed this was 32 bit)
sql/unireg.h:
  Extended the maximun key parts for an index from 16 to 32
storage/maria/ha_maria.cc:
  Don't allocate HA_CHECK on the stack in functions where we call repair() as HA_CHECK is HUGE and will overflow stack

  Added fflush() to fix output in case of error
  Fixed wrong check of 'ref' length in EXPLAIN

Fix of BUG#45632 (http://bugs.mysql.com/bug.php?id=45632) - sharing non default debug settings between sessions. This bugfix proposed by Monty.

mysql-test/r/variables_debug.result:
  Test that sessions do not share the same session debug variable.
mysql-test/t/variables_debug.test:
  Test that sessions do not share the same session debug variable.
sql/set_var.cc:
  As soon as default setting are shared between sessions we should push dbug state before changing debug setting first time.

Fix sleep() synchronisation in innodb_information_schema test case.

mysql-test/t/innodb_information_schema.test:
  Using sleep for synchronisation does not work!!!
  Replace by looping until the required condition is met.
sql-common/client.c:
  mysql_ssl_set() did not free old pointers before overwriting with new ones (happens when
  mysql_ssl_set() is called twice without calling mysql_close() in-between).
  
  This sometimes caused memory leaks in the slave depending on exact timing of
  master/slave shutdown.
  
  Fixed by freeing old pointers before installing new ones in mysql_ssl_set(), just like
  mysql_options() does.

 - Better fix for --innodb-use-sys-malloc causing Valgrind warnings.
 - Different fix for INNODB_IBUF_MAX_SIZE variable changing default value.
 - Fix some problems with the safe mutex lazy init patch.

mysql-test/include/mtr_check.sql:
  Do not check INNODB_IBUF_MAX_SIZE for changes. It is not a dynamic variable, so cannot
  be changed by a test case anyway, and the value may vary slightly from one start of the
  server to the next.
mysql-test/lib/mtr_cases.pm:
  Even just starting and stopping the server with --innodb-use-sys-malloc to check for
  disabled test case under valgrind will cause valgrind leak warnings. So add not_valgrind
  to the list of conditions also tested for directly in mysql-test-run.pl.
mysql-test/mysql-test-run.pl:
  Even just starting and stopping the server with --innodb-use-sys-malloc to check for
  disabled test case under valgrind will cause valgrind leak warnings. So add not_valgrind
  to the list of conditions also tested for directly in mysql-test-run.pl.
mysys/thr_mutex.c:
  Fix a few problems found during review of the lazy init safe mutex patch.
storage/xtradb/ibuf/ibuf0ibuf.c:
  Revert previous fix of INNODB_IBUF_MAX_SIZE default varying slightly between server starts.
  (Fixed instead by ignoring that variable in the test suite).

Manually merge some InnoDB changes into XtraDB.
Fix ALTER TABLE bug in XtraDB with wrong comparison of row type.

mysql-test/include/varchar.inc:
  Fix in test case that which of several duplicate keys triggers an error is not
  deterministic.
mysql-test/mysql-test-run.pl:
  InnoDB does not bother to free resources individually during shutdown, but due to using
  its own memory tracking it nevertheless can free everything at exit. But XtraDB adds an
  option, on by default, to skip this extra tracking. This causes lots of Valgrind
  warnings, so needs to be disabled for Valgrind testing.
mysql-test/r/innodb.result:
  Fix in test case that which of several duplicate keys triggers an error is not
  deterministic.
mysql-test/t/innodb-use-sys-malloc.test:
  InnoDB does not bother to free resources individually during shutdown, but due to using
  its own memory tracking it nevertheless can free everything at exit. But XtraDB adds an
  option, on by default, to skip this extra tracking. This causes lots of Valgrind
  warnings, so needs to be disabled for Valgrind testing.
sql/sql_table.cc:
  Add some useful DBUG while debugging alter table.
storage/xtradb/handler/ha_innodb.cc:
  Fix that check_if_incompatible_data did not realise that ROW_TYPE_DEFAULT is identical
  to the default row format ROW_TYPE_COMPACT, causing excessive table copying in
  ALTER TABLE
  Add some useful DBUG while debugging alter table.
  Manually merge into XtraDB a few small changes for InnoDB from upstream MySQL.
storage/xtradb/include/pars0pars.h:
  Manually merge into XtraDB a few small changes for InnoDB from upstream MySQL.
storage/xtradb/include/univ.i:
  Manually merge a MariaDB fix in InnoDB into XtraDB.

from Sergey's table-elimination branch to get a clean Valgrind.

include/my_sys.h:
  Move generic file parsing functions out to shared code, as they are used in several places.
mysys/mf_iocache2.c:
  Move generic file parsing functions out to shared code, as they are used in several places.
sql/log_event.cc:
  Fix XtraDB build with embedded server.
  XtraDB needs access to replication stuff, which is missing in embedded server.
  Solved by defining wrapper function for this which is compiled differently for normal and
  embedded case.
sql/log_event.h:
  Fix XtraDB build with embedded server.
  XtraDB needs access to replication stuff, which is missing in embedded server.
  Solved by defining wrapper function for this which is compiled differently for normal and
  embedded case.
sql/slave.cc:
  Move generic file parsing functions out to shared code, as they are used in several places.

The root of the problem is that ./configure mixed together two different things. One is the
availability of GCC atomic operation intrinsics. The other is the selection of which
primitives to use for my_atomic implementation.

Then at some point a hack was made to not use GCC intrinsics in my_atomic to work around
some test failures. But because the two things are mixed in ./configure, this as a side
effect also makes GCC intrinsics unavailable for XtraDB.

Fixed by splitting this in two in configure, so that we have HAVE_GCC_ATOMIC_BUILTINS for
GCC intrinsics availability and MY_ATOMIC_MODE_GCC_BUILTINS for use in my_atomic.

Fixes to get the test suite to run without failures.

storage/xtradb/srv/srv0start.c:
  Fix for MariaDB

The original XtraDB (and InnoDB plugin) is shipped as a separate source tree which is copied
into the MySQL source, after which a setup.sh script must be run to move things into place.

Now that XtraDB is part of the MariaDB source tree, this commit fixes these things up once
and for all:

 - New innodb build scripts.
 - Test suite fixes (new tests and patches to existing).
 - Remove files no longer needed due to this.

.bzrignore:
  XtraDB compiles innodb in storage/xtradb instead of storage/innobase
CMakeLists.txt:
  Take InnoDB code from storage/xtradb/ instead of storage/innobase/
libmysqld/CMakeLists.txt:
  Take InnoDB code from storage/xtradb/ instead of storage/innobase/

  Disable building old InnoDB from storage/innobase/ directory.
  
  We will keep the files around to avoid getting merge conflicts for every MySQL upstream
  change to InnoDB.
