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

sql/sql_table.cc:
  Add some useful DBUG while debugging alter table.

  Add some useful DBUG while debugging alter table.
  Manually merge into XtraDB a few small changes for InnoDB from upstream MySQL.

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.

  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:

  change to InnoDB.

 - Version number.
 - Valgrind false alarms in libz.
 - New variant of suppression for Valgrind warning in dlclose().
 - Fix double free() in plugin init error case.

configure.in:
  Fix version number. We should reset the maria variant back to `1' when the MySQL version
  number increases.
include/my_sys.h:
  Fix false alarms in Valgrind for zlib.
  
  Apply same fix as for archive storage handler also to the cases of compression in the
  client protocol, and to the compression SQL function.
mysql-test/valgrind.supp:
  A new variant of the dlclose() suppression is needed now.

Portability changes for Solaris 10 (amd64). Re-hash BUILD/ scripts for Solaris to be more in line with generic scripts.

Consequently, rename HAVE_purify to HAVE_valgrind, and related changes.
Leave some comments about purify when not clear that they apply also to Valgrind.
Fix redundant IF_VALGRIND declaration.

Misc. small fixes:
 - Fixes for pool-of-threads patch.
 - Fixes for push of PBXT storage engine.
 - mysql-test-run.pl fix.
 - Fix build problem in compile-pentium64-max.


BUILD/SETUP.sh:
  Rename purify -> valgrind.

  Rename purify -> valgrind.
BUILD/compile-dist:
  Fix that PBXT was missing in source tarball after `BUILD/compile-dist && make dist`
BUILD/compile-pentium64-max:
  Fix a build problem with BUILD/compile-pentium64-max on CentOS/Fedora Core 10 amd64.
        
  On these systems, there is libz.so but no libz.a. Finding libz.so, ./configure decides
  to use system zlib. But since BUILD/compile-pentium64-max builds a fully static binary
  with -all-static, the link of mysqld fails due to missing libz.a.
        
  Fix by using bundled zlib in the build script.

mysql-test/lib/mtr_unique.pm:
  Better fix to avoid races when chmod'ing the semaphore file.
  (Though using chmod 666 shared files in /tmp/ is still not a very good solution).
