  Remember the acquired record locks per table handle (row_prebuilt_t)

  unlock all non-matching rows in multi-table operations.
  This deficiency was found while investigating Bug #39320.

The dynamic plugin on Windows used to be built with MYSQL_SERVER
compile flag, while it is not the case for other platforms.
r3797 assumed MYSQL_SERVER was not defined for dynamic plugin,
which introduced the engine crash during dropping a database.

      BUG#42445 Warning messages in innobase/handler/ha_innodb.cc
            
      There was a type casting problem in the storage/innobase/handler/ha_innodb.cc,
      (int ha_innobase::write_row(...)). Innobase uses has an internal error variable
      of type 'ulint' while mysql uses an 'int'. 
            
      To fix the problem the function manipulates an error variable of
      type 'ulint' and only casts it into 'int' when needs to return the value.

  It was not a SIGSEGV but an assertion failure. The assertion was checking
  the invariant that *first_value passed in by MySQL doesn't contain a value
  that is greater than the max value for that type. The assertion has been
  changed to a check and if the value is greater than the max we report a
  generic AUTOINC failure.

Implement a check whether pthread_t objects can be used by GCC atomic
builtin functions. This check is implemented in plug.in and defines the
macro HAVE_ATOMIC_PTHREAD_T. This macro is checked in univ.i and the
relevant part of the code enabled (the one that uses GCC atomics against
pthread_t objects).

In addition to this, the same program that is compiled as part of the
plug.in check is added in ut/ut0auxconf.c. In the InnoDB Plugin source
archives that are shipped to the users, a generated Makefile.in is added.
That Makefile.in will be modified to compile ut/ut0auxconf.c and define
the macro HAVE_ATOMIC_PTHREAD_T if the compilation succeeds. I.e.
Makefile.in will emulate the work that is done by plug.in. This is done in
order to make the check happen and HAVE_ATOMIC_PTHREAD_T eventually
defined without regenerating MySQL's ./configure from
./storage/innobase/plug.in. The point is not to ask users to install the
autotools and regenerate ./configure.

Fix typo made in r4353.

As suggested by Ken, print a message that says that the Google SMP patch
(GCC atomics) is disabled if it is. Also extend the message when the patch
is partially enabled to make it clear that it is partially enabled.

Add FreeBSD to the list of the operating systems that have
sizeof(pthread_t) == sizeof(void*) (i.e. word size).

On FreeBSD pthread_t is defined like:

  /usr/include/sys/_pthreadtypes.h:

  typedef struct  pthread                 *pthread_t;

I did the following tests (per Inaam's recommendation):

a) appropriate version of GCC is available on that platform (4.1.2 or
higher for atomics to be available)

  On FreeBSD 6.x the default compiler is 3.4.6, on FreeBSD 7.x the default
  one is 4.2.1. One can always install the version of choice from the ports
  collection. If gcc 3.x is used then HAVE_GCC_ATOMIC_BUILTINS will not be
  defined and thus the change I am committing will make no difference.

b) find out if sizeof(pthread_t) == sizeof(long)

  On 32 bit both are 4 bytes, on 64 bit both are 8 bytes.

c) find out the compiler generated platform define (e.g.: __aix, __sunos__
etc.)

  The macro is __FreeBSD__.

d) patch univ.i with the appropriate platform define
e) build the mysql
f) ensure it is using atomic builtins (look at the err.log message at
system startup. It should say we are using atomics for both mutexes and
rw-locks)
g) do sanity testing (keeping in view the smp changes)

  I ran the mysql-test suite. All tests pass.

This is a fix for issue#178. Instead of using UNIV_LINUX which is
defined through CFLAGS we use compiler generated define __linux__
that is effective for both .c and .cc files.

This is to revert the changes made to the plug.in (r4251) as a fix for
issue# 178. Changes to plug.in will not propogate to a plugin
installation unless autotools are rerun which is unacceptable.

A fix for issue# 178 will be committed in a separate commit.

FIL_PAGE_TYPE mismatch even when purging a BLOB.
Heavy users may have large data files created with MySQL 5.0 or earlier,
and they don not want to have the error log flooded with such messages.

This fixes Issue #182.

Apply any necessary patches to the mysql tree at the end of setup.sh
This step was previously done manually (and sometimes forgotten).
