Done clean-up in prep stmt API functions: 1) Removed some checks that were performed only in debug version were making debug version more tolerable to user errors than production (and thus caused problems for example masking some bugs). 2) Also removed some other checks to make prep stmt API consistent with the rest of C API (this also in line with general politics - make checks in only those places where errors are very common and hard to spot). include/mysql.h: Removed CHECK_EXTRA_ARGUMENTS define since it is no longer used anywhere. libmysql/libmysql.c: Added check that will cause mysql_fetch() to bark then it is used without calling mysql_execute() before. Removed checks that were performed only in debug version and caused problems since they were making debug version more tolerable to user errors than production. Also removed some other checks to make prep stmt API consistent in this regard with the rest of C API (this also in line with general politics - make checks in only those places where errors are very common and hard to spot). tests/client_test.c: Updated tests to reflect removal of some checks in prep stmt API. Removed lines that caused bug #2473 to pop up, should be added as separate test with the fix for this bug. Added test for bug#2248 "mysql_fetch without prior mysql_execute hangs"
