This patch changes git-cvsimport-script so that it creates tag objects
instead of refs to commits, and adds an option, -u, to convert
underscores in branch and tag names to dots (since CVS doesn't allow
dots in branches and tags.)

Added -m and -M flags for git-cvsimport to detect merge commits in cvs.
While this trusts the commit message, in repositories where merge commits
indicate 'merged from FOOBRANCH' the import works surprisingly well.
Even if some merges from CVS are bogus or incomplete, the resulting
branches are in better state to go forward (and merge) than without any
merge detection.

I track a CVS project which has a branch with a '/' in the branch name.
Since git wants the branch name to be a file name at the same time,
substitute that character to a '-' by default (override with "-s <subst>").
This should work well, despite the fact that a division and a difference
are completely different :-)

Early versions of git-cvsimport defaulted to using preexisting keyword
expansion settings. This change preserves compatibility with existing cvs
imports and allows new repository migrations to kill keyword expansion.
After exploration of the different -k modes in the cvs protocol, we use -kk
which kills keyword expansion wherever possible. Against the protocol
spec, -ko and -kb will sometimes expand keywords.
Should improve our chances of detecting merges and reduce imported
repository size.

The git-cvsimport-script had a copule of small bugs that prevented me
from importing a big CVS repository.
The first was that it didn't handle removed files with a multi-digit
primary revision number.
The second was that it was asking the CVS server for "F" messages,
although they were not handled.
I also updated the documentation for that script to correspond to
actual flags.

Problems found while importing dasher's CVS:
* Allow spaces in filenames.
* cvsps may create unnamed branches with revisions that don't really
exist, which causes the CVS server to return something we haven't
hitherto expected.
* Report deleted files when being verbose.
* Also, report the commit date.

Previously, git-cvsimport-script would fail
on revisions with more than one digit.

git-cvsimport-script: add "import only" option which tells the script
not to perform a checkout after importing.
This ensures that the working directory and cache remain untouched and
will not create them if they do not exist.

This patch makes the first half of write_sha1_file() and
index_fd() externally visible, to allow callers to compute the
object ID without actually storing it in the object database.
[JC demangled the whitespaces himself because he liked the patch
so much, and reworked the interface to index_fd() slightly,
taking suggestion from Linus and of his own.]

If HEAD happened to point to a cvs branch, move the
working directory forward to the tip of the branch.
Additionally, if master and "origin" are equal,
move master forward to new origin first.
If we're inside a checked out CVS repository, there is
no need to explicitly specify the module as it is
available in CVS/Repository.
Also read CVS/Root if it's available and -d is not specified.
Finally, explicitly pass root to cvsps as CVS/Root takes
precedence over CVSROOT.

Add "-z fuzz" argument, passed to cvsps, and clean up argument
processing. Also, use "cvsps --cvs-direct", which is is somewhat
faster.
Give the user the option of specifying the timestamp fuzz passed to
cvsps. Looking at the other arguments to it, I can't see anything else
that would be sane to play with. Also, use --cvs-direct, which speeds
up cvsps for remote repositories and doesn't seem to do anything bad to
local repositories.

This patch adds some sanity checking to git-cvsimport-script,
specifically forcing the use of cvsps -x (to get the latest information
from the repository, rather than whatever is in the cache) and aborting
early if cvsps does not produce any output.
I debated removing the $MODULE directory following an abort, but I
eventually decided leaving stuff behind would make debugging easier. On
the other hand, this patch should help with the "cvsimport left me with
an empty repository" complaints.
Call cvsps with the -x flag, to get the current state of the repository,
and abort the cvs import early if cvsps does not produce any output.

This gets the "cvs2git" program from the old git-tools
archive, and adds a nice script around it that makes it
much easier to use.
With this, you should be able to import a CVS archive
using just a simple
git cvsimport <cvsroot> <module>
and you're done. At least it worked for my one single test.
NOTE!! This may need tweaking. It currently expects (and
verifies) that cvsps version 2.1 is installed, but you
can't actually set any of the cvsps parameters, like the
time fuzz.
