DELETE IGNORE should not ignore deadlocks

The error is due to conflict between min/max macros in my_global.h
and system header < limits>, indirectly included via generated 
probes_mysql_dtrace.h

Temporarily undefined min/max for the inclusion of the probes_mysq_dtrace.h

because of the high cost associated with  fake symdir resolution, disable symbolic-links on Windows by default. Real symlinks (Vista+) as well as NTFS junctions (prior to Vista) do not require this parameter

Removed const declarations to get rid of compiler warnings. The changes are similar to what is done in innobase in MySQL 5.5

BUILD/SETUP.sh:
  By default, build also with innodb-plugin
mysql-test/mysql-test-run.pl:
  Also search in lib64 directory for plugins (This is used at least on OpenSuse 12.1 when using default build scripts)
mysql-test/r/lock_multi.result:
  Allow test to be re-run even if it crashed.
mysql-test/t/lock_multi.test:
  Allow test to be re-run even if it crashed.
scripts/make_binary_distribution.sh:
  Ensure that libexecdir is named libexec (was not on OpenSuse 12.1)
scripts/mysql_config.sh:
  Fixed detection of lib64 was used.

This also fixes a (not likely) crashing bug when forcing a thread that was doing a table lock to re-open it's files, for example by creating a trigger.


mysys/thr_lock.c:
  Added more checking to find wrong locks.
  Removed one, not needed, parameter to thr_lock
sql/lock.cc:
  Fixed mysql_lock_tables() to retry with new sql_lock if lock fails. This was needed as table may be closed and reopened between retry's and then the old sql_lock will point to stale data.
sql/mysql_priv.h:
  Updated prototype
sql/sql_base.cc:
  Ensure that all tables are closed if opening of system table failes; This fixes the assert in THD::restore_backup_open_tables_state
sql/sql_handler.cc:
  Updated variable type

Fix memory leak in one error case in mysqldump.
Fix that HAVE_VALGRIND_VALGRIND_H is now HAVE_VALGRIND in 5.5.
Fix that @have_ssl should not be set in embedded (introduced when
removing #undef HAVE_OPENSSL from my_global.h).

always try to use valgrind headers in debug builds.
define HAVE_valgrind for --with-valgrind
fix valgrind check in my_valgrind.h

 execution which mtr --embedded does not support

Sort counters by their names (otherwise, the order of SHOW STATUS output is sometimes sorted and sometimes not)

 Handler_mrr_key_refills, Handler_mrr_rowid_refills.

VIO has SSL in embedded server anyway, so we do not win anything by excluding it.

This was actually already done in this changeset:

    revision-id: kostja@sun.com-20100413150445-8x23keoxdiufgq76

"... Also, he removed the (probable) bug of embedded server never using SSL-dependent functions..."
But was apparenly lost by a mis-merge of WL#5030.

UNIX_TIMESTAMP() can be null, and returns null for invalid values

Fixed compiler warnings found by buildbot

Makefile.am:
  Removed extra empty line
cmd-line-utils/libedit/sys.h:
  Fixed that strndup() doesn't give compiler warnings
mysql-test/Makefile.am:
  Fixes for 'make distcheck'
plugin/auth_pam/auth_pam.c:
  Ensure that prototype for strndup() is included on linux
sql/share/Makefile.am:
  Fixes for 'make distcheck'
storage/innodb_plugin/btr/btr0sea.c:
  Fixed compiler warning
support-files/Makefile.am:
  Fixes for 'make distcheck'

mysql-test/suite/innodb_plugin/t/innodb_gis.test:
  Don't run test if innodb_plugin isn't used.
