Always seed the LCG from the request-init hook, otherwise the seed
would be shared among the threads which is quite pointless. Also
use a function of the current time as one factor.

Use gettimeofday() instead of time(), because it is faster on some
operating systems.

revert last commit. Guys, discuss such things first, then commit. Mkay?

Add an API function for setting the session id from a session module...

# The SRM folks wanted/needed this

- Don't wrap lines... this is annoying while coding.

Restore session_adapt_url()

Cleanup and clarify

define_sid updates

Fix trans_sid handler registration logic

Cleanup

More fixes and refinements

Fix my session updates.
trans_sid handling will no longer slow down performance unless a session
is actually in use.

Fix trans-sid.
Still need to figure out how to turn trans-sid only when sessions
are actually used.

Make the session module more independent

Get rid of TRANS_SID - it's always possible to use it now.

Move the trans-sid mechanism to use the output buffering mechanism.
Advantages:
- Would work with the output buffering mechanism in general, and with
output compression in particular

- Should yield better performance (untested as of yet)

Track down a few more functions that don't check for 0 args and use

We don't consistently check for args passed to functions that don't

We don't consistently check for args passed to functions that don't
take any args. In some cases we probably want to skip the check for
performance reasons, but in other cases where performance is unlikely
to be a factor, not throwing a warning on the wrong number of args passed
to a function is at best inconsistent, and at worst it could hide a bug.
So, add a few such checks. There are still lots of cases out there.
