move a brace down in devel_shutdown() so the ['devel_shutdown'] marker actually does soemthing. thanks Earl.

i picked wrong solution for #140417 - avoid breaking javascript/image pages with devel_shutdown() output

- Code didn't correctly handle sites where the 'Switch users'
  permission has been granted to the 'authenticated users' role.
- Queries didn't properly filter out uid 0.
- Queries were not PgSQL compliant.

should prefer to list users that are allowed to switch, and visually
mark them (via theme('placeholder')) so you know who can switch back.

once again, the query log and friends are compatible with page cache. we even output a query log even if a cached page was served. useful for assuring you are fully optimized for cached pages. no longer using javascript to output the query log ... AHAH and other pages can use ['devel_shutdown'] = FALSE to suppress devel output

rollback of ltr patch. i am not seeing devel output render on page properly with this. the section is empty

move lots of devel_exit() stuff like query log and memory log to a shutdown function. we now get more accurate memory usage and more importantly, the 2 write queries in sess_write() at the end of every request are now shown. lets get rid of one or both of these through refactoring of throttle and who's online features.

automatically show large data structures within a textarea during dprint_r(). early code by irakli. modified by moshe weitzman ... minor function rename too

remove automatic block enable feature. it didn't work 100%, and some folks dislike the php block in particular

show sumamry query information even when query log is disabled and timer enabled. also change a bunch of strtr to t() since we rejiggered bootstrapo so that t() is legal in hook_init and hook_exit()

the variable viewer is replaced by a fine variable editor. patch by moshe weitzman ... i would be pleased if someone figured out how to add the fancy checkbox range behavior to this form.
