Remove ASM for MC68000 and Vax.

Remove 32-bit SPARC specific code.

into actual tree. No conflicts.

* Fixed obvious errors (HAVE_BROKEN_PREAD is not true for on any
of systems we use, definitely not on HPUX)

* Remove other junk flags for OSX and HPUX

* Avoid checking type sizes in universal builds on OSX, again 
(CMake2.8.0 fails is different architectures return different results)

* Do not compile template instantiation stuff unless 
EXPLICIT_TEMPLATE_INSTANTIATION is used.

* Some cleanup (make gen_lex_hash simpler, avoid dependencies)

* Exclude some unused files from compilation (strtol.c etc)

Fix some issues with WiX packaging, particularly 
major upgrade and change scenarios.

* remember binary location and data location
(for major upgrade)

* use custom UI, which is WiX Mondo extended 
for major upgrade dialog (no feature selection
screen shown on major upgrade, only upgrade
confirmation). This is necessary to prevent
changing installation path during upgrade
(services are not reregistered, so they would 
have invalid binary path is it is changed)

* Hide datafiles that are installed into 
ProgramFiles, show ones that are installed
in ProgramData

* Make MSI buildable with nmake

* Fix autotools "make dist"

Fix assorted warnings in order for the warning-mode to be effective.

Post-merge fix: remove remaining casts which are now
unnecessary and are actually causing warnings.

Remove wrappers around inline -- static inline is used without
wrappers throughout the source code. We rely on the compiler or
linker to eliminate unused static functions.

Remove workarounds for ancient systems.

  Make cast more explicit to ensure a correct offset.

Remove unused string functions.

include/m_string.h:
  Remove prototypes for unused string functions and for functions
  that do not exist anymore.

Remove unused macros or macro which are always defined.

include/my_global.h:
  Remove unused macros and move macros which aren't used globally.

has been removed.

Remove Windows related files which aren't used anymore.

Remove unused variables.

Remove code that has been disabled for a long time.

The reason for the bug above is unclear but
- Modify pfs_upgrade so that it's result is easier to analyze in case something fails
- Fix several minor weaknesses which could cause that a successing test (either an
  already existing or a to be developed one) fails because of imperfect cleanup,
  too slow disconnected sessions etc.
should either fix the bug or reduce it's probability or at least
make the analysis of failures easier.

Bug#52261: 64 bit atomic operations do not work on Solaris i386
           gcc in debug compilation

One of the various problems was that the source operand to
CMPXCHG8b was marked as a input/output operand, causing GCC
to use the EBX register as the destination register for the
CMPXCHG8b instruction. This could lead to crashes as the EBX
register is also implicitly used by the instruction, causing
the value to be potentially garbaged and a protection fault
once the value is used to access a position in memory.

Another problem was the lack of proper clobbers for the atomic
operations and, also, a discrepancy between the implementations
for the Compare and Set operation. The specific problems are
described and fixed by Kristian Nielsen patches:

Patch: 1

Fix bugs in my_atomic_cas*(val,cmp,new) that *cmp is accessed
after CAS succeds.

In the gcc builtin implementation, problem was that *cmp was
read again after atomic CAS to check if old *val == *cmp;
this fails if CAS is successful and another thread modifies
*cmp in-between.

In the x86-gcc implementation, problem was that *cmp was set
also in the case of successful CAS; this means there is a
window where it can clobber a value written by another thread
after successful CAS.

Patch 2:

Add a GCC asm "memory" clobber to primitives that imply a
memory barrier.

This signifies to GCC that any potentially aliased memory
must be flushed before the operation, and re-read after the
operation, so that read or modification in other threads of
such memory values will work as intended.

In effect, it makes these primitives work as memory barriers
for the compiler as well as the CPU. This is better and more
correct than adding "volatile" to variables.

include/atomic/gcc_builtins.h:
  Do not read from *cmp after the operation as it might be
  already gone if the operation was successful.
include/atomic/nolock.h:
  Prefer system provided atomics over the broken x86 asm.
include/atomic/x86-gcc.h:
  Do not mark source operands as input/output operands.
  Add proper memory clobbers.
include/my_atomic.h:
  Add notes about my_atomic_add and my_atomic_cas behaviors.
unittest/mysys/my_atomic-t.c:
  Remove work around, if it fails, there is either a problem
  with the atomic operations code or the specific compiler
  version should be black-listed.

This bug is a design flaw of the fix for the bug#33546. It assumed that an
item can be used only in one comparison context, but actually it isn't the
case. Item_cache_datetime is used to store result for MIX/MAX aggregate
functions. Because Arg_comparator always compares datetime values as INTs when
possible the Item_cache_datetime most time caches only INT value. But
since all datetime values has STRING result type MIN/MAX functions are asked
for a STRING value when the result is being sent to a client. The
Item_cache_datetime was designed to avoid conversions and get INT/STRING
values from an underlying item, but at the moment the values is asked
underlying item doesn't hold it anymore thus wrong result is returned.
Beside that MIN/MAX aggregate functions was wrongly initializing cached result
and this led to a wrong result.

The Item::has_compatible_context helper function is added. It checks whether
this and given items has the same comparison context or can be compared as
DATETIME values by Arg_comparator. The equality propagation optimization is
adjusted to take into account that items which being compared as DATETIME
can have different comparison contexts.
The Item_cache_datetime now converts cached INT value to a correct STRING
DATETIME value by means of number_to_datetime & my_TIME_to_str functions.
The Arg_comparator::set_cmp_context_for_datetime helper function is added. 
It sets comparison context of items being compared as DATETIMEs to INT if
items will be compared as longlong.
The Item_sum_hybrid::setup function now correctly initializes its result
value.
In order to avoid unnecessary conversions Item_sum_hybrid now states that it
can provide correct longlong value if the item being aggregated can do it
too.

mysql-test/r/group_by.result:
  Added a test case for the bug#49771.
sql/item.cc:
  Bug#49771: Incorrect MIN/MAX for date/time values.
  The equality propagation mechanism is adjusted to take into account that
  items which being compared as DATETIME can have different comparison
  contexts.
  The Item_cache_datetime now converts cached INT value to a correct STRING
  DATETIME/TIME value.
sql/item.h:
  Bug#49771: Incorrect MIN/MAX for date/time values.
  The Item::has_compatible_context helper function is added. It checks whether
  this and given items has the same comparison context or can be compared as
  DATETIME values by Arg_comparator.
  Added Item_cache::clear helper function.
sql/item_cmpfunc.cc:
  Bug#49771: Incorrect MIN/MAX for date/time values.
  The Arg_comparator::set_cmp_func now sets the correct comparison context
  for items being compared as DATETIME values.
sql/item_cmpfunc.h:
  Bug#49771: Incorrect MIN/MAX for date/time values.
  The Arg_comparator::set_cmp_context_for_datetime helper function is added. 
  It sets comparison context of items being compared as DATETIMEs to INT if
  items will be compared as longlong.
sql/item_sum.cc:
  Bug#49771: Incorrect MIN/MAX for date/time values.
  The Item_sum_hybrid::setup function now correctly initializes its result
  value.
sql/item_sum.h:
  Bug#49771: Incorrect MIN/MAX for date/time values.
  In order to avoid unnecessary conversions Item_sum_hybrid now states that it
  can provide correct longlong value if the item being aggregated can do it
  too.

Put '-features=no%except' back into Solaris/x86 CXXFLAGS.

This assert checks that the server does not try to send OK to the
client if there has been some error during processing. This is done
to make sure that the error is in fact sent to the client.

The problem was that view errors during processing of WHERE conditions
in UPDATE statements where not detected by the update code. It therefore
tried to send OK to the client, triggering the assert.
The bug was only noticeable in debug builds.

This patch fixes the problem by making sure that the update code
checks for errors during condition processing and acts accordingly.

Post-merge fix: remove leftovers from safemalloc removal.
