This makes "ci" codepath lockless by following the usual
"remember the tip, do your thing, then compare and swap at the
end" update pattern using update-ref. Incidentally, by updating
the code that reads where the tip of the head is to use
show-ref, it makes it safe to use in a repository whose refs are
pack-pruned.
I noticed that other parts of the program are not yet pack-refs
safe, but tried to keep the changes to the minimum.

git-cvsserver is analogous to git-receive-pack; a checking from a cvs
client to a central server is like a git-push from a working repository.
Therefore it's nice to use the same access control (and email sending)
that a receive-pack would perform.
This patch tests for an executable update hook; if it is it is run with
the ref being updated and the old and new hashes as normal. If the
update hook returns an error code the update is aborted and the ref is
never updated. The cvsserver returns "error 1" to the client to signal
there was an EPERM error.

If a repository was checked out via git-cvsserver and then later a new
file is added to the git repository via some other method; a CVS update
wasn't fetching the new file.
It would be reported as a new file as
A some/dir/newfile.c
but would never appear in the directory.
The problem seems to be that git-cvsserver was treating these two cases
identically, as "A" type results.
1. New file in repository
2. New file locally
In fact, traditionally, case 1 is treated as a "U" result, and case 2
only is treated as an "A" result. "A", should just report that the file
is added locally and then skip that file during an update as there is
(of course) nothing to send.
In both these cases there is no working revision, so the checking for
"is there no working revision" will return true. The test for case 2
needs refining to say "if there is no working revision and no upstream
revision". This patch does just that, leaving case 1 to be handled by
the normal "U" handler.
I've also updated the log message to more accurately describe the
operation. i.e. that "A" means that content is scheduled for addition;
not that it actually has been added.

At some point between v5.6 and 5.8 Perl started to assume its input,
output and filehandles are UTF-8. This breaks the counting of bytes
for the CVS protocol, resulting in the client expecting less data
than we actually send, and storing truncated files.

Tonight I found a git-cvsserver instance spending a lot of time in
disk IO while trying to process operations against a Git repository
with >30,000 objects contained in it.
Blowing away my SQLLite database and rebuilding all tables with
indexes on the attributes that git-cvsserver frequently runs queries
against seems to have resolved the issue quite nicely.
Since the indexes shouldn't hurt performance on small repositories
and always helps on larger repositories we should just always create
them when creating the revision storage tables.

git-update-ref writes into the lockfile, and renames it afterwards. Like
commit v1.3.0-rc3~22, it is not only cleaner, but also helps with shared

* Implemented global -n option
* Implemented "Questionable"
* Fixed Directory method, I _believe_ it's now correct in both cmdline and Eclipse.
* Directory method Now looks for localdir of "." and compares the repo dir, uses THIS as a basis for all directory level calculations.
* Added extra parameter to filenamesplit() to force stripping of "prepended" directory name. This ensures commits/updates etc work from any directory in the source tree.
* Modified argsfromdir() so it is "always" called. This means that when the client specifies a directory, the method can detect this and behave accordingly (this is currently only implemented for the '.' directory)
* Fixed "commit" method to correctly work from in a subdir

This has been an unfortunate sideway in the git API evolution.
We use git-repo-config for all the other .git/config interaction

git-cvsserver now knows how to do the pserver auth chat when the user
is anonymous. To get it to work, add a line to your inetd.conf like
cvspserver stream tcp nowait nobody git-cvsserver pserver
(On some inetd implementations you may have to put the pserver parameter twice.)
Commits are blocked. Naively, git-cvsserver assumes non-malicious users. Please
review the code before setting this up on an internet-accessible server.
NOTE: the <nobody> user above will need write access to the .git directory
to maintain the sqlite database. Updating of the sqlite database should be
put in an update hook to avoid this problem, so that it is maintained by
users with write access.
We now have different error messages when the repo is not found vs repo is
not configured to allow gitcvs. Should help users during initial checkouts.

To create nested directories without (or before) sending file entries
is rather tricky. Most clients just work. Eclipse, however, expects
a very specific sequence of events. With this patch, cvsserver meets
those expectations.
Note: we may want to reuse prepdir() in req_update -- should move it
outside of req_co. Right now prepdir() is tied to how req_co() works.

A recent Eclipse compat fix broke checkouts with -d. Fix it so that the server
sends the correct module name instead of the destination directory name.
Just by sending the files in an ordered fashion, clients can process them
much faster. And we can optimize our check of whether we created this
directory already -- faster.
Timings for a checkout on a commandline cvs client for a project with
~13K files totalling ~100MB:
Unsorted:
603.12 real 16.89 user 42.88 sys
Sorted:
298.19 real 26.37 user 42.42 sys
The Eclipse client uses cvs update when that menu option is triggered.
And doesn't like the standard cvs update response. Give it *exactly* what
it wants.
And hope the other clients don't lose the plot too badly.

Initial checkouts were failing to create Entries files under Eclipse.
Eclipse was waiting for two non-standard directory-resets to prepare for a new
directory from the server.
This patch is tricky, because the same directory resets tend to confuse other
clients. It's taken a bit of fiddling to get the commandline cvs client and
Eclipse to get a good, clean checkout.

Eclipse CVS clients have an odd way of perusing the top level of
the repository, by calling update on module "". So reproduce cvs'
odd behaviour in the interest of compatibility.
It makes it much easier to get a checkout when using Eclipse.
A few things to satisfy Eclipse's strange habits as a cvs client:
- Implement Questionable
- Aliased rlog to log, but more work may be needed
- Add a space after the U that indicates updated
git-cvsserver is highly functional. However, not all methods are implemented,
and for those methods that are implemented, not all switches are implemented.
All the common read operations are implemented, and add/remove/commit are
supported.
Testing has been done using both the CLI CVS client, and the Eclipse CVS
plugin. Most functionality works fine with both of these clients.
Currently git-cvsserver only works over SSH connections, see the
Documentation for more details on how to configure your client. It
does not support pserver for anonymous access but it should not be
hard to implement. Anonymous access will need tighter input validation.
In our very informal tests, it seems to be significantly faster than a real
CVS server.
This utility depends on a version of git-cvsannotate that supports -S and on
DBD::SQLite.
