cvsserver t9400: add basic 'cvs log' test

'cvs log' output is arguably deficient in a number of ways
(see the comment added with the test), but add a test for
the current output to detect for accidental regressions.

cvsserver: removed unused sha1Or-k mode from kopts_from_path

sha1Or-k was a vestige from an early, never-released
attempt to handle some oddball cases of CRLF conversion (-k option).
Ultimately it wasn't needed, and I should have gotten rid of it
before submitting the CRLF patch in the first place.

See also 90948a42892779 (add ability to guess -kb from contents).

cvsserver: remove unused functions _headrev and gethistory

Remove:
   - _headrev() - It uses similar functionality from getmeta() and gethead().
   - gethistory() - It uses similar functions gethistorydense() and getlog().

cvsserver: use whole CVS rev number in-process; don't strip "1." prefix

Keep track of the whole CVS revision number in-process.  This will
clarify code when we start handling non-linear revision numbers later.

There is one externally visible change: conflict markers after
an update will now include the full CVS revision number,
including the "1." prefix.  It used to leave off the prefix.

Other than the conflict marker, this change doesn't effect
external functionality.  No new features, and the DB schema
is unchanged such that it continues to store just
the stripped rev numbers (without prefix).

cvsserver: cvs add: do not expand directory arguments

Standard "cvs add" never does any recursion.  With standard
cvs, "cvs add dir" will either add just the "dir" to
the repository, or error out.  Prior to this change, git-cvsserver
would try to recurse (perhaps re-adding sandbox-removed files?) into
the existing directory instead.

cvsserver: define a tag name character escape mechanism

CVS tags are officially only allowed to use [-_0-9A-Za-f].  Git
refs commonly uses other characters, especially [./].  Such characters
need to be escaped from CVS in order to be referenced.

This just defines functions to escape/unescape names.  The functions
are not used yet.

cvsserver: add misc commit lookup, file meta data, and file listing functions

These will be used soon, but not yet.

PERFORMANCE NOTE: getMetaFromCommithash() does not scale well as currently
implemented.  See comment for possible optimization strategies.
Fortunately, it will only be used in cases that would not have worked
at all before this change.

cvsserver: support -r and sticky tags for most operations

  - Split off prepDirForOutput for "update" and "commit".
    Some low level protocol details were changed to more closely
    resemble CVS even in non-tagged cases.  Hopefully it still works
    with finicky clients like Eclipse.
  - Substantial changes to "diff".  The output is now closer to
    standard CVS (including exit status), and can be used as
    a patch, but there are still a number of differences compared
    to CVS.
  - Tweaks to "add", "remove", "status", and "commit".
  - FUTURE: CVS revision numbers for branches simply encode git
    commit IDs in a way that resembles CVS revision numbers,
    dropping all normal CVS structural relations between different
    revision numbers.
  - FUTURE: "log" doesn't try to work properly at all with branches
    and tags.
  - FUTURE: "annotate" probably doesn't work with branches or
    tags either (untested)?
