Add some examples for using libmysqld, including a hack for running the

mysql test suite.

A few minor libmysqld fixes.

Add mysql_server_init() and _end() to mysql.cc and mysqltest.c, so they
can be linked against libmysqlclient or libmysqld.


sql/mysqld.cc:
  have unireg_end() exit(), instead of pthread_exit()
  if inside the EMBEDDED_LIBRARY.  This is a hack
  which hopefully won't be needed.  But without it,
  the program hangs at end.
client/mysql.cc:
  Don't call mysql_ssl_clear() unless HAVE_OPENSSL.
client/mysqltest.c:
  Add mysql_server_init() and _end().
acinclude.m4:
  change .. to $(top_builddir) in innodb_libs
Makefile.am:
  Add libmysqld/examples to link_sources target
configure.in:
  output libmysqld/examples/Makefile
  Also, change .. to $(top_builddir) in readline_link
BitKeeper/etc/ignore:
  added linked_libmysqldex_sources
mysql-test/mysql-test-run.sh:
  use latin1, not latin1_de, in tests
libmysqld/libmysqld.c:
  Add replication functions.
