Some intersections with Monty encountered

  Initial cleanup edits.

Added new HOWTO doc 'INSTALL-WIN-SOURCE' on building 'mysql clients and server' on WINDOWS from BitKeeper as well as from distributed source archive

merged conflicts about my previous commit
it seems there are some errors left - gonna check...

client capabilities included into libmysqld
some API methods became "virtual"
lots of duplicated code removed

   consistent with the other column names in the table.
