MWL#192: non-blocking client API, after-review fixes.

Browse Source 
Main change is that non-blocking operation is now an option that must be
explicitly enabled with mysql_option(mysql, MYSQL_OPT_NONBLOCK, ...)
before any non-blocing operation can be used.

Also the CLIENT_REMEMBER_OPTIONS flag is now always enabled and thus
effectively ignored (it was not really useful anyway, and this simplifies
things when non-blocking mysql_real_connect() fails).

It used to be that if mysql_real_connect() failed, it would delete any
options set by the client, unless the CLIENT_REMEMBER_OPTIONS flag was
given.
That behaviour does not appear very useful, and it seems unlikely that
any applications would actually depend on this. So from MariaDB 5.5 we
always preserve any options set in case of failed connect, and this
option is effectively always set.
