SCRUM
common parts of libmysql.c and sql/mini_client.cc moved to sql-common/client.c names of functions now are same in both cases libmysql/libmysql.c: many parts moved to sql-common/client.c libmysqld/Makefile.am: superfluous files removed sql/mini_client.cc: most of the file moved to sql-common/client.c sql/mini_client.h: mc_ prefixes were deleted sql/repl_failsafe.cc: mc_ prefixes removed sql/slave.cc: _mc prefixes removed
