[PATCH] config.txt: Add gitcvs.db* variables

[Frank Lichtenheld <frank@lichtenheld.de>]

Adds documentation for gitcvs.{dbname,dbdriver,dbuser,dbpass}
Texts are mostly taken from git-cvsserver.txt whith some
adaptions so that they make more sense out of the context
of the original man page.

 Note that this one is made on top of the cvsserver topic
 branch and my fixes to config.txt (i.e. the description
 for gitcvs.allbinary is in the context of the patch).
 Just saying.

+gitcvs.dbname::
+	Database used by git-cvsserver to cache revision information
+	derived from the git repository. The exact meaning depends on the
+	used database driver, for SQLite (which is the default driver) this
+	is a filename. Supports variable substitution (see
+	gitlink:git-cvsserver[1] for details). May not contain semicolons (`;`).
+	Default: '%Ggitcvs.%m.sqlite'

+gitcvs.dbdriver::
+	Used Perl DBI driver. You can specify any available driver	
+        for this here, but it might not work. git-cvsserver is tested
+	with 'DBD::SQLite', reported to work with 'DBD::Pg', and
+	reported *not* to work with 'DBD::mysql'. Experimental feature.
+	May not contain double colons (`:`). Default: 'SQLite'.

+
+gitcvs.dbuser, gitcvs.dbpass::
+	Database user and password. Only useful if setting 'gitcvs.dbdriver',
+	since SQLite has no concept of database users and/or passwords.
+	'gitcvs.dbuser' supports variable substitution (see
+	gitlink:git-cvsserver[1] for details).
+
+All gitcvs variables except for 'gitcvs.allbinary' can also specifed
+as 'gitcvs.<access_method>.<varname>' (where 'access_method' is one
+of "ext" and "pserver") to make them apply only for the given access
+method.
