Embedded mysql fixes.

There is now a mysql_server_init() function which needs to be
called at the beginning of the program (and _end() for the end
of the program).  This routine handles argument parsing for the
embedded server.

Use the embedded version of mysql_load_file() (ignore the LOCAL
argument, since the client and server are the same program).

There are now mysql_thread_init/end() functions for the client
to use in a multi-threaded app.  They are just wrappers for
my_thread_init/end().

-1) unpack mysql-3.23.27-beta.tar tarball source version (get from www.mysql.com.sg)
-2) patch  mysql-3.23.27-beta with lbver-3.23.27-beta.diff:
-   patch -p0 <lbver-3.23.27-beta.diff
-3) cd mysql-3.23.27-beta 
-4) autoconf
-7) ./configure --prefix=/usr/local/mysql --with-library-version
-8) make  	
-9) make install  	(should have the root privileges)
-10)mkdir /usr/local/mysql/var (if not already)
-15) cd ../client
-19) ./mysql   (start libarary version mysql)
-mysql> create database db1;
-mysql> use db1;
-mysql> create table a123(i integer)
