Comment (by nacin):

 [27257] additionally forces mysqli for development environments. This
 should increase testing during 3.9 beta.

 [attachment:21663.13.diff] adds a constant called USE_EXT_MYSQL. Rather
 than the more forward-thinking driver approach, this simply restricts it
 to applying to the enabling/disabling of ext/mysql.

 I actually first had it only allow for the disabling of ext/mysql via
 USE_EXT_MYSQL = false. USE_EXT_MYSQL = true wouldn't force ext/mysql on
 PHP 5.5. The patch does this, however, since it may be useful to force
 ext/mysql for development/testing purposes, and because it's inevitable
 this will break a PHP 5.5 site, so let's ensure we have easy recourse.
