#554838 by Dave Reid, savlis: Fixed phantom menu items and block errors on module disable or uninstall.

Remove SMTP library. Was conflicting with new simpletest provided library. Use reroute_mail module or other at http://drupal.org/project/modules?filters=tid:66&solrsort=sort_title%20asc

Update for PDO. Removed the storage of queries. Perhas this can be resurrected in http://drupal.org/project/arooga or other module. Or back into devel ... Also reworked the module reinstall UI.

create menu link for run cron with devel as owning module. also menu.inc is not that smart. it does not use the module column for uninstall. thats a bug IMO. anyway, i worked around this in devel_uninstall().

updated for new wildcard syntax (%node) and new watchdog() params. all that is left for full HEAD compliance is fapi3 changes.

minor fixes #79236 add block rehash, #78521 dprint_r() gets html encoding, #78520 dpr() is now a true alias of dprint_r(), #78518 phpinfo body gets get stripped properly

to fix up module weights for existing installs.
