[development] Debugging updates

[Moshe Weitzman]

I haven't used it much, but devel has the ability to store all queries
into the database. see admin/settings/devel. unfortunately,
devel_shutdown() specifically bails on update.php because we used to
output gunk and wreck the JSON thats returned. We should really be
smarter and allow the logging but not allow output to screen. patches
welcome.

If I use update_sql() I can tell what queries ran, but there are times when I need to use db_query() instead and I can get no clue to what is going on when that runs. And I can't find any way to display messages back to myself or see results of print_r() or any of the other things I do elsewhere to debug scripts.
