For a given project the directory used with the -w option is almost always
the same each time. Let it be specified with 'cvsexportcommit.cvsdir' so
it's not necessary to manually add it with -w each time.

If you have a CVS checkout, it is easy to import the CVS history by
calling "git cvsimport". However, interacting with the CVS repository
using "git cvsexportcommit" was cumbersome, since that script assumes
separate working directories for Git and CVS.
Now, you can call cvsexportcommit with the -W option. This will
automatically discover the GIT_DIR, and it will check out the parent
commit before exporting the commit.
The intended workflow is this:
$ CVSROOT=$URL cvs co module
$ cd module
$ git cvsimport
hack, hack, hack, making two commits, cleaning them up using rebase -i.
$ git cvsexportcommit -W -c -p -u HEAD^
$ git cvsexportcommit -W -c -p -u HEAD

In commit fef3a7cc(cvsexportcommit: be graceful when "cvs status"
reorders the arguments), caution was taken to get the status even
for files with leading or trailing whitespace.
However, the author of that commit missed that chomp() removes only
trailing newlines. With help of the mailing list, the author realized
his mistake and provided this patch.
The idea is that we do not want to rely on a certain layout of the
output of "cvs status". Therefore we only call it with files that are
unambiguous after stripping leading and trailing whitespace.

When using the '-w $cvsdir' option to cvsexportcommit, it will chdir into
$cvsdir before executing several other git commands. If $GIT_DIR is set to
a relative path (e.g. '.'), the git commands executed by cvsexportcommit
will naturally fail.
Therefore, ensure that $GIT_DIR is absolute before the chdir to $cvsdir.

In my use cases, "cvs status" sometimes reordered the passed filenames,
which often led to a misdetection of a dirty state (when it was in
reality a clean state).
I finally tracked it down to two filenames having the same basename.
So no longer trust the order of the results blindly, but actually check
the file name.
Since "cvs status" only returns the basename (and the complete path on the
server which is useless for our purposes), run "cvs status" several times
with lists consisting of files with unique (chomped) basenames.
Be a bit clever about new files: these are reported as "no file <blabla>",
so in order to discern it from existing files, prepend "no file " to the
basename.
In other words, one call to "cvs status" will not ask for two files
"blabla" (which does not yet exist) and "no file blabla" (which exists).
This patch makes cvsexportcommit slightly slower, when the list of changed
files has non-unique basenames, but at least it is accurate now.

Because we feed the changed filenames to CVS on the command
line, it was possible for massive commits to overflow the
system exec limits. Instead, we now do an xargs-like split
of the arguments.
This means that we lose some of the atomicity of calling CVS
in one shot. Since CVS commits are not atomic, but the CVS
protocol is, the possible effects of this are not clear;
however, since CVS doesn't provide a different interface,
this is our only option for large commits (short of writing
a CVS client library).
The argument size limit is arbitrarily set to 64kB. This
should be high enough to trigger only in rare cases where it
is necessary, so normal-sized commits are not affected by
the atomicity change.

If git cvsexportcommit is executed fast enough in sequence, the CVS
timestamps could end up being the same. CVS tries to fix this
by sleeping until the CPU clock changes seconds. Unfortunately,
the CPU clock and the file system clock are not necessarily the same, so
the timestamps could be the same anyway. When that happens CVS may not
recognize changed files and cvs will forget to commit some files.

Runtime is now independent of the number of modified files.

to be applied. The new code calls 'cvs status' only once with all touched files

Unlike 'patch --fuzz=NUM', which specifies the number of lines allowed
to mismatch, 'git-apply -CNUM' requests the match of NUM lines of
context. Omitting -C requests full context match, and that's what
should be used for cvsexportcommit -p.

This patch uses git-apply to do the patching which simplifies the code a lot
and also uses one pass to git-diff. git-apply gives information on added,
removed files as well as which files are binary.
Removed the test for checking for matching binary files when deleting them
since git-apply happily deletes the file. This is matter of taste since we
allow some fuzz for text patches also.
Error handling was cleaned up, but not much tested.
