BuildSystem/Windows: * Added 5.1.50 (GA) MySQL client sources for crosscompiling (or lazy) windows people.
* Added an option to autosearch for your own installed MySQL as before. Note that default setting is to use the internal MySQL. * You can now build 32-bit even if your MySQL is x64 and vice versa. * Recommended MySQL server version for use with provided MySQL client sources is 5.1.x. * If your server version is different, let CMake autofind and use it instead (check EXTERNAL_MYSQL option) --HG-- branch : trunk

+ 'length' is the maximum length of the string; the buffer needs
+ to be one character larger to accomodate the terminating '\0'.
+ This is easy to get wrong, so we make sure we write to the
+ entire length of the buffer to identify incorrect buffer-sizes.
+ We only initialise the "unused" part of the buffer here, a) for
+ efficiency, and b) because dst==src is allowed, so initialising
+ the entire buffer would overwrite the source-string. Also, we
+ write a character rather than '\0' as this makes spotting these
+ problems in the results easier.
