First batch of PHP4/MySQL compatibility/performance changes.

Browse Source 
Everything should be non-intrusive for installations meeting our new 4.1.0/3.23.32 specs.

I will commit my files every now and then for easier code review and to let you see which constructs I replace. Jump in if there are any objections. The basic thing I'm doing is documented in the changelog.

I'll continue with files in the libraries/ subdirectory and will move to the root-level files in last instance.

* libraries/auth/*, libraries/dbg/*, libraries/export/*
(work in progress)
Lots of PHP < 4.1.0 / MySQL < 3.23.32 compatibility/performance changes:
- Replaced "while (list() = each())" calls by foreach loops.
- Removed PHP3-compatibility code
- Removed calls to $HTTP_*_VARS (using $_* now).
- Replaced some TAB-characters with whitespace
- Removed PHP4 < 4.1.0 compatibility code
- Replaced "for ($i=0; $i <= count(); $i++)" loops to
"$cnt = count(); for ($i=0; $i <= $cnt; $i++)" structures for better
performance
