Don't show PEAR packages in the user info for a PECL developer.

Apparently PEAR packages were never completely purged from the
database when the PECL website was detached from pear.php.net.
There may certainly be more places around where PEAR packages
should be excluded. And the best long term solution would be
to get rid of them in the database completely.

Bug #62399
handle direct visits to package-search.php as a no results page
set the created field for the unapproved accounts and use that information for sorting the outstanding requests and display it in the grid
we never set $errors here
removing the duplicate new_package form element, keeping the dropdown is a better choice, and the label for the removed input was also misleading(New Package Name)
Ask users for a supporting/sponsoring user
Keep newlines in output
Use a single simple query instead of multiple join queries
List package name
