The autotools-based build system has been superseded and
is being removed in order to ease the maintenance burden on
developers tweaking and maintaining the build system.
In order to support tools that need to extract the server
version, a new file that (only) contains the server version,
called VERSION, is introduced. The file contents are human
and machine-readable. The format is:
MYSQL_VERSION_MAJOR=5
MYSQL_VERSION_MINOR=5
MYSQL_VERSION_PATCH=8
MYSQL_VERSION_EXTRA=-rc
The CMake based version extraction in cmake/mysql_version.cmake
is changed to extract the version from this file. The configure
to CMake wrapper is retained for backwards compatibility and to
support the BUILD/ scripts. Also, a new a makefile target
show-dist-name that prints the server version is introduced.
VERSION:
Add top-level version file.
cmake/mysql_version.cmake:
Get version information from the top-level VERSION file.
Do not cache the version components (MAJOR_VERSION, etc).
Add MYSQL_RPM_VERSION as a replacement for MYSQL_U_SCORE_VERSION.

first part, for autotools build.
config/ac-macros/maintainer.m4:
Add the flag. With it, and as we use -Werror, we nicely get
"error: ISO C90 forbids mixed declarations and code" if
a declaration follows a statement in C code.
Note that g++ refuses this flag.

Enable the MySQL maintainer-specific development environment
(which add various warning related options to the compiler
flags) if debugging support is enabled.
config/ac-macros/maintainer.m4:
Enable the maintainer mode if debug support is enabled.
configure.in:
Move debug argument to before the maintainer mode check.

Temporarily disable strict aliasing warnings in order to get
wider coverage for optimized builds. Once the violations are
fixed and false-positives silenced, this flag should be removed.

of autoconf and is not strictly needed for now.

Introduce a MySQL maintainer/developer mode that enables
a set of warning options for the C/C++ compiler. This mode
is intended to help improve the overall quality of the code.
The warning options are:
C_WARNINGS="-Wall -Wextra -Wunused -Wwrite-strings -Werror"
CXX_WARNINGS="$C_WARNINGS -Wno-unused-parameter"
Since -Wall is essentially a moving target, autoconf checks
are not run with warning options enabled, in particualr -Werror.
This decision might be revisited in the future. The patch also
fixes a mistake in the makefiles, where automake CXXFLAGS would
be set to CFLAGS.
config/ac-macros/maintainer.m4:
Add a set of default compiler flags used when in maintainer mode.
configure.in:
Hook into the maintainer mode. Disabled by default.
