Updated manual about embedded version.
Speed up column-completion in 'mysql' Don't use ISAM if HAVE_ISAM is not defined A lot of fixes for the embedded version. All libraries are now included in libmysqld.a Changed arguments to convert_dirname() to make it more general. Renamed files in the 'merge' directory to all use a common prefix. Don't compile both assembler and C functions on x86
