unknown 0de9a4abab MWL#74: Shared libmysqld.so library.
Switch makefiles to use libtool to build libmysqld.so, as well as all its
dependencies.

The previous MYSQL_PLUGIN_DEPENDS_ON_MYSQL_INTERNALS() declaration is removed,
as it does not work well with a libtool build. Instead, plugins that need it
can specify an alternate object in MYSQL_PLUGIN_STATIC() that will be used for
embedded library. The plugin must then take care itself of compiling the
special object for embedded, rebuilding the source files previously listed in
MYSQL_PLUGIN_DEPENDS_ON_MYSQL_INTERNALS() with @plugin_embedded_defs@ in
CFLAGS/CXXFLAGS. The extra target @XXX_embedded_static_target@ is available
for the special object, this will be empty when --without-embedded-server.

All in-tree plugins are changed to build their static targets with libtool.
Additional plugins that want to work with libmysqld.so will need to be
similarly modified to build with libtool (or otherwise provide an -fPIC
object). Dynamically loaded plugins are not affected.

The old libraries like libmysys.a, libmyisam.a and similar libraries, which
were installed by `make install` though this is of little use, are still built
and installed to not break package scripts etc. that expect them. These
libraries are kept static to avoid introducing new .so dependencies.

The patch also fixes a handfull of duplicate symbol linker errors, where we
included some object twice during linking; these for one reason or another did
not produce errors before but caused problems on some platforms with this
patch (eg. Mac OS X linker is more strict for shared objects).

This patch only does what is necessary to build libmysqld.so. There are some
more cleanups that are possible now that we are using libtool more fully,
which could done in subsequent patches (though we may not bother as we are
switching from autotools to CMake anyway):

 - In libmysql_r/, we should be able to just link libmysys.la etc, instead of
   symlinking and re-compiling sources into the directory.

 - In libmysql/, we can similarly avoid symlinking and recompiling sources if
   we instead build a libmysys_nothread.la library with appropriate CFLAGS and
   link that.

 - In sql/, we can build a separate target libmysql_int.la with appropriate
   CFLAGS for embedded and use that in libmysqld/ instead of symlinking
   sources.

 - libmysys.a, libmyisam.a and similar libraries could be installed as .so
   also to save on code size; or alternatively could be not installed at all.

Unit tests directory structure
------------------------------

This is the current structure of the unit tests.  More directories
will be added over time.

mytap                 Source for the MyTAP library
mysys                 Tests for mysys components
  bitmap-t.c          Unit test for MY_BITMAP
  base64-t.c          Unit test for base64 encoding functions
examples              Example unit tests.
  core-t.c            Example of raising a signal in the middle of the test
		      THIS TEST WILL STOP ALL FURTHER TESTING!
  simple-t.c          Example of a standard TAP unit test
  skip-t.c            Example where some test points are skipped
  skip_all-t.c        Example of a test where the entire test is skipped
  todo-t.c            Example where test contain test points that are TODO
  no_plan-t.c         Example of a test with no plan (avoid this)


Executing unit tests
--------------------

To make and execute all unit tests in the directory:

   make test

Observe that the tests in the examples/ directory are just various
examples of tests and are not expected to pass.


Adding unit tests
-----------------

Add a file with a name of the format "foo-t.c" to the appropriate
directory and add the following to the Makefile.am in that directory
(where ... denotes stuff already there):

  noinst_PROGRAMS = ... foo-t

Note, it's important to have "-t" at the end of the filename, otherwise the
test won't be executed by 'make test' !


Documentation
-------------

The generated documentation is temporarily placed at:

      http://www.kindahl.net/mytap/doc/

I will move it to a better place once I figure out where and how.
