revlog: use compression engine API for compression

This commit swaps in the just-added revlog compressor API into
the revlog class.

Instead of implementing zlib compression inline in compress(), we
now store a cached-on-first-use revlog compressor on each revlog
instance and invoke its "compress()" method.

As part of this, revlog.compress() has been refactored a bit to use
a cleaner code flow and modern formatting (e.g. avoiding
parenthesis around returned tuples).

On a mozilla-unified repo, here are the "compress" times for a few
commands:

$ hg perfrevlogchunks -c
! wall 5.772450 comb 5.780000 user 5.780000 sys 0.000000 (best of 3)
! wall 5.795158 comb 5.790000 user 5.790000 sys 0.000000 (best of 3)

$ hg perfrevlogchunks -m
! wall 9.975789 comb 9.970000 user 9.970000 sys 0.000000 (best of 3)
! wall 10.019505 comb 10.010000 user 10.010000 sys 0.000000 (best of 3)

Compression times did seem to slow down just a little. There are
360,210 changelog revisions and 359,342 manifest revisions. For the
changelog, mean time to compress a revision increased from ~16.025us to
~16.088us. That's basically a function call or an attribute lookup. I
suppose this is the price you pay for abstraction. It's so low that
I'm not concerned.

The standalone Windows installer for Mercurial is built in a somewhat
jury-rigged fashion.

It has the following prerequisites. Ensure to take the packages
matching the mercurial version you want to build (32-bit or 64-bit).

  Python 2.6 for Windows
      http://www.python.org/download/releases/

  A compiler:
    either MinGW
      http://www.mingw.org/
    or Microsoft Visual C++ 2008 SP1 Express Edition
      http://www.microsoft.com/express/Downloads/Download-2008.aspx

  Python for Windows Extensions
      http://sourceforge.net/projects/pywin32/

  mfc71.dll (just download, don't install; not needed for Python 2.6)
      http://starship.python.net/crew/mhammond/win32/

  Visual C++ 2008 redistributable package (needed for >= Python 2.6 or if you compile with MSVC)
    for 32-bit:
      http://www.microsoft.com/downloads/details.aspx?FamilyID=9b2da534-3e03-4391-8a4d-074b9f2bc1bf
    for 64-bit:
      http://www.microsoft.com/downloads/details.aspx?familyid=bd2a6171-e2d6-4230-b809-9a8d7548c1b6

  The py2exe distutils extension
      http://sourceforge.net/projects/py2exe/

  GnuWin32 gettext utility (if you want to build translations)
      http://gnuwin32.sourceforge.net/packages/gettext.htm

  Inno Setup
      http://www.jrsoftware.org/isdl.php#qsp

      Get and install ispack-5.3.10.exe or later (includes Inno Setup Processor),
      which is necessary to package Mercurial.

  ISTool - optional
      http://www.istool.org/default.aspx/

  add_path (you need only add_path.exe in the zip file)
      http://www.barisione.org/apps.html#add_path

  Docutils
      http://docutils.sourceforge.net/

  CA Certs file
      http://curl.haxx.se/ca/cacert.pem

And, of course, Mercurial itself.

Once you have all this installed and built, clone a copy of the
Mercurial repository you want to package, and name the repo
C:\hg\hg-release.

In a shell, build a standalone copy of the hg.exe program.

Building instructions for MinGW:
  python setup.py build -c mingw32
  python setup.py py2exe -b 2
Note: the previously suggested combined command of "python setup.py build -c
mingw32 py2exe -b 2" doesn't work correctly anymore as it doesn't include the
extensions in the mercurial subdirectory.
If you want to create a file named setup.cfg with the contents:
[build]
compiler=mingw32
you can skip the first build step.

Building instructions with MSVC 2008 Express Edition:
  for 32-bit:
    "C:\Program Files\Microsoft Visual Studio 9.0\VC\vcvarsall.bat" x86
    python setup.py py2exe -b 2
  for 64-bit:
    "C:\Program Files\Microsoft Visual Studio 9.0\VC\vcvarsall.bat" x86_amd64
    python setup.py py2exe -b 3

Copy add_path.exe and cacert.pem files into the dist directory that just got created.

If you are using Python 2.6 or later, or if you are using MSVC 2008 to compile
mercurial, you must include the C runtime libraries in the installer. To do so,
install the Visual C++ 2008 redistributable package. Then in your windows\winsxs
folder, locate the folder containing the dlls version 9.0.21022.8.
For x86, it should be named like x86_Microsoft.VC90.CRT_(...)_9.0.21022.8(...).
For x64, it should be named like amd64_Microsoft.VC90.CRT_(...)_9.0.21022.8(...).
Copy the files named msvcm90.dll, msvcp90.dll and msvcr90.dll into the dist
directory.
Then in the windows\winsxs\manifests folder, locate the corresponding manifest
file (x86_Microsoft.VC90.CRT_(...)_9.0.21022.8(...).manifest for x86,
amd64_Microsoft.VC90.CRT_(...)_9.0.21022.8(...).manifest for x64), copy it in the
dist directory and rename it to Microsoft.VC90.CRT.manifest.

Before building the installer, you have to build Mercurial HTML documentation
(or fix mercurial.iss to not reference the doc directory):

  cd doc
  mingw32-make html
  cd ..

If you use ISTool, you open the C:\hg\hg-release\contrib\win32\mercurial.iss
file and type Ctrl-F9 to compile the installer file.

Otherwise you run the Inno Setup compiler.  Assuming it's in the path
you should execute:

  iscc contrib\win32\mercurial.iss /dVERSION=foo

Where 'foo' is the version number you would like to see in the
'Add/Remove Applications' tool.  The installer will be placed into
a directory named Output/ at the root of your repository.
If the /dVERSION=foo parameter is not given in the command line, the
installer will retrieve the version information from the __version__.py file.

If you want to build an installer for a 64-bit mercurial, add /dARCH=x64 to
your command line:
  iscc contrib\win32\mercurial.iss /dARCH=x64

To automate the steps above you may want to create a batchfile based on the
following (MinGW build chain):

  echo [build] > setup.cfg
  echo compiler=mingw32 >> setup.cfg
  python setup.py py2exe -b 2
  cd doc
  mingw32-make html
  cd ..
  iscc contrib\win32\mercurial.iss /dVERSION=snapshot

and run it from the root of the hg repository (c:\hg\hg-release).
