Fix typo causing too low timeout value for wait_for_slave_param.inc.
Fix binlog checksums following 5.5 merge.
Make sure the rpl suite can run with --mysqld=--binlog-checksum=CRC32
Fix a number of problems in the code when checksums are enabled.

give mysqld more time to start under valgrind

fix safemalloc to compile w/o libbfd.

CMakeLists.txt:
  NOT_FOR_DISTRIBUTION option
cmake/readline.cmake:
  simplify libedit/readline detection.
  never use bundled libedit.
  use system readline v6 only if NOT_FOR_DISTRIBUTION=1
configure.cmake:
  use libbfd only if NOT_FOR_DISTRIBUTION=1
include/my_stacktrace.h:
  link with libbfd even w/o safemalloc.

* rename all debugging related command-line options
  and variables to start from "debug-", and made them all
  OFF by default.
* replace "MySQL" with "MariaDB" in error messages
* "Cast ... converted ... integer to it's ... complement"
  is now a note, not a warning
* @@query_cache_strip_comments now has a session scope,
  not global.

remeber a real backtrace for every allocation.
make safemalloc to tract C++ new/delete too.
collateral fixes to make the test suite pass.

- leaking mutex in lf_hash_destroy
- pthread_getspecific() before pthread_key_create() in my_thread_var_dbug()
(called by static C++ object constructors called in sys_vars)
- perfschema destroys mutexes that were  not created.

Default to no SAFEMALLOC on Windows, because C runtime malloc
has this functionslity already

Replace statements connected with bitwise OR with series of "if"s.
The later is guaranteed to execute in order, bitwise OR does not have
specific order for statement execution.

cmake/maintainer.cmake:
  don't do -Werror just yet
config.h.cmake:
  according to MSDN PSAPI_VERSION should be 1 in a portable application
mysys/my_thr_init.c:
  first, reset THR_KEY_mysys, and then free dbug data,
  because dbug data are automacially created on the next dbug call,
  unless THR_KEY_mysys is null.

- build executables we have in 5.3 (mysql_install_db.exe, mysq_upgrade_service.exe, upgrade wizard), and MSI

- add some missing headers to windows specific source files. 
This needs to be done since 5.5 is using WIN32_LEAN_AND_MEAN preprocessor constant thus windows.h 
no more includes whiole Windows

- do not deliver perl scripts  (mysql_install_db.pl & friends)  -they do not work, are not documented, and we 
have native executables for this functionality. do not pack echo.exe, replace.exe  into MSI, they 
are not needed. Do not build resolveip on Windows, it is not used.

- precache results of  of system checks in cmake/os/WindowsCache.cmake (like it is alreay done for  majority of tests
to speed up cmake run with VS)

- make feedback plugin DEFAULT on Windows (so MSI works if user enables plugin), 
fix null pointer access in PSI_register

A variable XTRADB_PREFER_STATIC_LIBAIO should be set to 1 (or TRUE
 or ON) for static linking.

Even if mysqld can avoid dependency on shared libaio, shared libraries 
libmysqld.so or ha_innodb.so cannot link without it.

Given that the patch primarily addresses building tar.gz package, and 
shared libraries mentioned above deemed less important than mysqld
executable, we accept shared lib dependency on libaio.so

Hardcode -MariaDB suffix for MYSQL_SERVER_VERSION in mysql_version.h

Make max_user_connections signed, with min allowed value being -1.

So removed.

the depth of subquery nestedness to less than 31
(sizeof(ulong)-1).
