Modify plugins.m4 configuration framework so that plugins which are
not built still get added to the source distribution during make dist.
This came up now because we can only build ibmdb2i on i5/OS, and we
can't bootstrap our source dist on that platform.  The solution is to
specify DIST_SUBDIRS containing all plugins, separate from SUBDIRS
which contains the plugins which are actually built.

This ibmdb2i code is from the ibmdb2i-ga3-src.zip file, with a patch
to plug.in to disable the plugin if the PASE environment isn't available.

TRUNCATE TABLE fails to replicate when stmt-based binlogging is not supported.

Correcting some tests that was failing in pushbuild as well as fixing result
file for some tests that are not executed in the default MTR run.

mysql-test/suite/binlog/t/binlog_truncate_innodb.test:
  Need to reset master to avoid the check to be for the wrong binlog file.
mysql-test/suite/binlog/t/binlog_truncate_myisam.test:
  Need to reset master to avoid the check to be for the wrong binlog file.

Post-merge fixes. Changes to some result sets.

mysql-test/r/commit_1innodb.result:
  TRUNCATE TABLE does not cause the binary log to do commits any more.
mysql-test/suite/binlog/r/binlog_row_mix_innodb_myisam.result:
  TRUNCATE TABLE is not transactional, hence does not have BEGIN/COMMIT around itself.
mysql-test/suite/binlog/r/binlog_stm_mix_innodb_myisam.result:
  TRUNCATE TABLE is not transactional, hence does not have BEGIN/COMMIT around itself.
mysql-test/suite/rpl/r/rpl_innodb_mixed_dml.result:
  TRUNCATE TABLE is not transactional, hence does not have BEGIN/COMMIT around itself.
mysql-test/suite/rpl/r/rpl_truncate_2myisam.result:
  STOP SLAVE was replaced with include file.
mysql-test/suite/rpl/r/rpl_truncate_3innodb.result:
  STOP SLAVE was replaced with include file.

Perl crashes when MTR 2 tries to start v1
Replaced require with system()

mysql-test/t/null.test:
  Revert fix for bug 33699.

The problem is that a unfiltered user query was being passed as
the format string parameter of sql_print_warning which later
performs printf-like formatting, leading to crashes if the user
query contains formatting instructions (ie: %s). Also, it was
using THD::query as the source of the user query, but this
variable is not meaningful in some situations -- in a delayed
insert, it points to the table name.

The solution is to pass the user query as a parameter for the
format string and use the function parameter query_arg as the
source of the user query.

This involves just the tag, no file changes - they were all present before.

In 37553 we declared longlong results for
class Item_str_timefunc as per comments/docs,
but didn't add a method for that. And the
default just wasn't good enough for some
cases.

Changeset adds dedicated val_int() to class.

mysql-test/r/func_sapdb.result:
  More tests for casts of TIME() / TIMEDIFF() with negative results.
mysql-test/t/func_sapdb.test:
  More tests for casts of TIME() / TIMEDIFF() with negative results.
sql/item_timefunc.h:
  Since we claim to provide longlong results, we should have
  a suitable function to provide them (the default won't do).
  This one matches the val_real() variant.

TRUNCATE TABLE fails to replicate when stmt-based binlogging is not supported.

There were two separate problems with the code, both of which are fixed with
this patch:

1. An error was printed by InnoDB for TRUNCATE TABLE in statement mode when
   the in isolation levels READ COMMITTED and READ UNCOMMITTED since InnoDB
   does permit statement-based replication for DML statements. However,
   the TRUNCATE TABLE is not transactional, but is a DDL, and should therefore
   be allowed to be replicated as a statement.

2. The statement was not logged in mixed mode because of the error above, but
   the error was not reported to the client.

This patch fixes the problem by treating TRUNCATE TABLE a DDL, that is, it is
always logged as a statement and not reporting an error from InnoDB for TRUNCATE
TABLE.

mysql-test/suite/binlog/t/binlog_truncate_innodb.test:
  Adding test for testing that TRUNCATE TABLE is logged correctly for InnoDB
  in all isolation levels.
mysql-test/suite/binlog/t/binlog_truncate_myisam.test:
  Adding test for testing that TRUNCATE TABLE is logged correctly for MyISAM.
mysql-test/suite/binlog/t/disabled.def:
  Disabling binlog_truncate_innodb since it does not work (yet).
sql/sql_base.cc:
  Correcting setting of capabilities flags to make the comparison with 0
  later in the code work correctly.
sql/sql_delete.cc:
  Re-organizing code to ensure that TRUNCATE TABLE is logged in statement
  format and that row format is not used unless there are rows to log (which
  there are not when delete_all_rows() is called, so this has to be logged
  as a statement).

- remove the disbling of all ssl_* tests now when certs are fixed.

The problem is that MySQL use of pthread_setschedprio is not
supported by i5/OS and the default system behavior for unsupported
calls is to emit a SIGILL signal which causes the server to
abort.

The solution is to treat the pthread_setschedprio as inexistent
when compiling binaries for i5/OS. This also does not invalidate
the fix for bug 38477 as the only supported dispatch class is
SCHED_OTHER (which is passed to pthread_setschedparam).

configure.in:
  Skip pthread_setschedprio check on i5/OS.
