Note: to build with -fno-rtti as we currently build the server, boost version  1.45 or later is required.
(without -fno-rtti, 1.40 is enough)

Fix oqgraph build . Plugin does not need rtti, and does not load if rtti compile settings are different from server's

Fixed memory leak printing when doing 'mysqld --version', 'mysqld --debug --help' and 'mysqld --debug --help --verbose'


mysys/my_init.c:
  Moved checking if we should call DBUG_END() before my_thread_end() as otherwise we will not free DBUG variables and files.
mysys/thr_lock.c:
  Fixed compiler warning
sql/mysqld.cc:
  Fixed memory leaks when using mysqld --help and mysqld --version
  Added --debug as an option that works for all builds. For non debug builds we now get a warning.
strings/dtoa.c:
  Fixed valgrind warning (c could contain data outside of the given string)

Fix things so that chains of certificates work in the server and client
certificate files.

This only really works for OpenSSL-based builds, as yassl is unable to read
multiple certificates from a file.  The patch below to yassl/src/ssl.cpp
doesn't fix that, but just arranges that the viosslfactories.c patch won't
have any ill effects in a yassl build.

it is a static library that links with shared libraries, so strictly speaking it should
have -fPIC or equivalent flags. Also, it must always build as static no matter
whether  BUILD_SHARED_LIBS is set.

that caused the default value to be written into an arbitrary location inside
global_system_variables

* MYSQL_MAINTAINER_MODE and SAFEMALLOC take values ON/OFF/AUTO
  (in all builds, in none, only in debug and platform dependent)
* ./configure prefers RelWithDebInfo unless the user overrides

(and to follow the naming conventons).
keep old debug variable, but mark it as deprecated.

Files copied from Percona-Server-5.5.17-rel22.1.tar.gz source tarball.

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.
