Fixes and code cleanups after merge with 4.0.3

Warning handling and initial prepared statement handling (last not complete yet) Changed a lot of functions that returned 0/1 to my_bool type. GRANT handling now uses read/write locks instead of mutex Change basic net functions to use THD instead of NET (needed for 4.1 protocol) Use my_sprintf instead of sprintf() + strlen() Added alloc_query() to be able to chare query initialization code with prepared statements. Cleanup handling of SHOW COUNT(*) WARNINGS and SELECT LAST_INSERT_ID() Note that the following test fails (will be fixed ASAP): sub_select, union, rpl_rotate_logs and rpl_mystery22
