[PATCH/RFC] cvsserver: Make configuration way more flexible

[Frank Lichtenheld <frank@lichtenheld.de>]

Hi.

This patch series started with the thought that it is really cumbersome
to use the pserver access via git-cvsserver without giving the
nobody user write access to the .git directory itself (especially since
SQLite seems to insist on creating temporary files in the
same directory as the database itself on writes).

This problem itself is easily fixable with an one-line patch
to git-cvsserver that uses a gitcvs.dbdir configuration variable.

I tried to abstract the problem a bit more though and created
means to configure all aspects of the database backend in a
very flexible manner. I would glad about comments on wether
I made my solution overly complex on the way...

Most of the changes are tested intensively with test repositories,
exceptions are noted in the individual patches. More testing welcome
of course.

The documentation updates are not yet complete.

Gruesse,
	Frank Lichtenheld
