Fix for Bug#31173: mysqlslap.exe crashes if called without any parameters

.bzrignore:
  Fixed .bzrignore rules. Many were simply not ignoring what they were meant to.
client/mysqlslap.c:
  Fixed bug for Bug#31173: mysqlslap.exe crashes if called without any parameters
  The original patch could cause memory leaks and odd problems depending on how connection was made.
  This code ensures that all mysql_options() are set for each mysql_real_connect().
  (This patch by Monty)
mysys/my_thr_init.c:
  Fixed multiply-initialized critical section on Windows, due to code incorrectly
  checking the wrong field in an attempt to prevent multiple-initialization.
sql-common/client.c:
  Don't use shared memory if it's not set (for example after failed mysql_real_connect).
  Ensure that mysql_close() resets all resources so that it's safe to call it twice.
  (Patch by monty, related to Bug#31173: mysqlslap.exe crashes if called without any parameters)
sql/CMakeLists.txt:
   Added page fault counters for SHOW PROFILE on Windows.
sql/mysqld.cc:
  Fixed attempt to set a NULL event. The code now only sets the event if appropriate (i.e. shared memory is being used)
sql/sql_profile.cc:
  Added page fault counters for SHOW PROFILE on Windows.
sql/sql_profile.h:
  Added page fault counters for SHOW PROFILE on Windows.
sql/udf_example.def:
  Some cleanup functions were not exported from udf_example.dll, causing them to
  never be executed, and as a result multiple-initialization of kernel objects
  occurred and resources were not being freed correctly.
storage/maria/ma_close.c:
  Condition variable share->key_del_cond was never being destroyed, while its
  containing heap block was being freed in maria_close(), leaking kernel
  resources.

d13c54351d Remove compiler warnings (Including some warnings from -Wstrict-aliasing)
Don't use static link by default (in compile-pentium) as some new systems doesn't have all static libraries available
Change type for functions in plugin.h:str_mysql_ftparser_param() to const unsigned char and string lengths to size_t.
One effect of the above change is that one needs to include mysql_global.h or define size_t before including plugin.h

d4db598110 Additional fix for bug #45613: handle failures from my_hash_insert
Testing for presence of stuff in a hash inside the function
that's filling in the hash creates chicken-and-egg type of problems.
This results in test suite failures in mysql-pe in debug mode and 
adds bad initialization dependency in 5.1.
Fixed by removing the debug code.

a962160eec Merge with MySQL 5.1, with following additions:
- Moved some code from innodb_plugin to xtradb, to ensure that all tests runs
- Did changes in pbxt and maria storage engines becasue of changes in thd->query
- Reverted wrong code in sql_table.cc for how ROW_FORMAT is used.

This is a re-commit of Monty's merge to eliminate an extra commit from
MySQL-5.1.42 that was accidentally included in the merge.

This is a merge of the MySQL 5.1.41 clone-off (clone-5.1.41-build). In
case there are any extra changes done before final MySQL 5.1.41
release, these will need to be merged later before MariaDB 5.1.41
release.

0ba101d4ea Bug#46586: When using the plugin interface the type "set" for options caused a crash.
"What do you mean, there's a bug? There isn't even code!"

There was some token code for plug-in variables of the SET type,
but clearly this never worked, or was subject to massive bit rot
since. Bug-fixes ... fail-safes ... tests -- fais au mieux, mon chou!

mysys/my_getopt.c:
  SETs set-up should set up a default value, but no min/max bounding.
mysys/typelib.c:
  fail-safe requested by serg: don't try to skip separator when we're
  already at end of string.
sql/sql_plugin.cc:
  check_func_set:
  Initialize error_len as find_set() will only update it on error,
  and we're using the value to see whether an error has occurred (!= 0),
  so we'd better not have a random val in there.
  
  value_ptr:
  There's no guarantee we're handed string lengths, so play it safe!
  Use prepared string lengths where possible for minimum speed gain,
  otherwise determine on the fly!

   Grabs the mutex and discovers one waiter. It set
   the broadcast event and closes the broadcast gate
   then unlocks the mutex.
3) A third thread (III) issues a pthread_cond_signal.
   It grabs the mutex, discovers one waiter, sets the
   signal event then unlock the mutex.
4) The first threads (I) enters WaitForMultipleObjects
   and finds out that the signal object is in a
   signalled state and exits the wait.
5) Thread (I) grabs the mutex and checks result status.
   The number of waiters is decreased and becomes equal
   to 0. The event returned was a signal event so the
   broadcast gate isn't opened. The mutex is released.
6) Thread (II) issues a new broadcast. The mutex is
   acquired but the number of waiters are 0 hence
   the broadcast gate remains closed.
7) Thread (I) enters the wait again but is blocked by
   the broadcast gate.

      This fix resolves the above issue by always resetting
      broadcast gate when there are no more waiters in th queue.


mysys/my_wincond.c:
  * Always reset the broadcast gate if there are no more waiters left.

4d57b851a0 WL#4259 - Debug Sync Facility
Backport from 6.0 to 5.1.
Only those sync points are included, which are used in debug_sync.test.

  The Debug Sync Facility allows to place synchronization points
  in the code:
  
  open_tables(...)
  
  DEBUG_SYNC(thd, "after_open_tables");
  
  lock_tables(...)
  
  When activated, a sync point can
  
  - Send a signal and/or
  - Wait for a signal
  
  Nomenclature:
  
  - signal:            A value of a global variable that persists
                       until overwritten by a new signal. The global
                       variable can also be seen as a "signal post"
                       or "flag mast". Then the signal is what is
                       attached to the "signal post" or "flag mast".
  
  - send a signal:     Assign the value (the signal) to the global
                       variable ("set a flag") and broadcast a
                       global condition to wake those waiting for
                       a signal.
  
  - wait for a signal: Loop over waiting for the global condition until
                       the global value matches the wait-for signal.
  
  Please find more information in the top comment in debug_sync.cc
  or in the worklog entry.

db89051656 Fix bug#46980
Option "--without-server" still not working in 5.1

The general approach is to make sure that source files
which require thread support are only compiled if the build
really needs thread support,
which means when the server is built or a thread-safe client
library.

This required several changes:
- Make sure the subdirectories "storage/" and "plugin/" are
  only processed if the server is built, not ifclient-only.
- Make the compilation of some modules which inherently
  require threading depend on thread supportin the build.
- Separate the handling of threading in "configure.in" from
  that of server issues, threading is also needed in a
  non-server build of a thread-safe client library.

Also, "libdbug" must get built even in a client-only build,
so "dbug/" must be in the list of client directories.

In addition, calls to thread functions in source files which
can be built without thread support must use the wrapper
functions which handle the non-threaded build.
So the modules "client/mysqlimport.c" and "client/mysqlslap.c"
must call "my_thread_end()" only via "mysql_thread_end()".


Makefile.am:
  The directories "storage/" and "plugin/" contain files
  which are needed for the server only, so their contents
  is to be built only if a server is built.
  
  They must not be named unconditionally, because building
  their contents will fail unless threads are enabled.
  
  These directories are now listed in the "configure"
  variable "sql_server_dirs" which becomes part of
  "sql_union_dirs" if the server is to be built.
client/mysqlimport.c:
  Use the wrapper function "mysql_thread_end()" which
  correctly handles the case of a non-threaded build.
client/mysqlslap.c:
  Use the wrapper function "mysql_thread_end()" which
  correctly handles the case of a non-threaded build.
configure.in:
  Various changes to support builds "--without-server":
  
  1) For the unit tests, we need "libdbug".
  
  2) Separate the treatment of the server from that of the
     thread-safe client library.
  
  3) Introduce an "automake conditional" "NEED_THREAD"
     which can be checked in some "Makefile.am".
  
  4) Include "storage/" and "plugin/" in the list of
     "sql_server_dirs" so that they are handled in the
     top "Makefile.am" only if the server is to be built
     (see the change in that file).
mysys/Makefile.am:
  The code of "mf_keycache.c" in 5.1 is no longer safe
  to be built without thread support.
  (In 5.0, this was possible.)
  
  Rather than fix these issues, which is tedious and risky,
  avoid the need to ever build it without thread support:
  It is needed in the server only, which needs thread support.
  
  The only case where we build a "libmysys" without thread
  support is for a non-threaded client, where "mf_keycache"
  is not neded.
  So its inclusion in the list of source files can depend
  on the new conditional "NEED_THREAD".
unittest/mysys/Makefile.am:
  Test program "my_atomic-t" is to verify the correct handling
  of threads only, it cannot be built without thread support
  and is not needed in such cases either.
  
  Let its build depend on the new conditional "NEED_THREAD".
