intent to drop a new 3.0 feature into CVS..

I plan on dropping my authentication cleanups into cvs at the end of
this week.

The main reason to do so is not the cleanups themselves (although they
are important :}), but rather the unit tests that I've put with them -
which demonstrate how to do unit tests to core bits of squid that
require much of squid linked in and initialised.

I've attached the current delta - its a tla delta, so just ignore all
the .id files, and the {arch} files - they are meta data that CVS won't
see.

things to note are:
the removal of the auth_modules.sh script - modules are activated by
linking, movement towards a consistent method based api, the separation
of scheme(ntlm/digest/basic) and configuration - which will eventually
allow multiple active configurations of ntlm/digest etc - and the
src/tests/testAuth.{h,cc} test script.
