Decrease running time for getStringList (and all other get methods) by
looking for configuration entries using binary search rather than
linear search through the configuration file.

Configuration lines are sorted by section, subsection, name in a
sorted list whenever the snapshot is rebuilt. Binary search is used to
locate an index in the middle of the values, then walk backwards to
find the first value in the range.

Given a configuration of file of 5000 distinct section/subsection/name
triplets (e.g. a Gerrit Code Review project.config configuration file
with 5000 unique access control rules), this new code is faster to
lookup each rule individually using getStringList():

  old setStringList() 194 usec avg
      getStringList() 196 usec avg

  new setStringList() 188 usec avg
      getStringList()  24 usec avg

Rename detection should be considered enabled if
diff.renames config property is set to "copy" or "copies", instead of
throwing IllegalArgumentException.

The automatically generated commit message of a merge should have the
same structure as in C Git for consistency (as per git fmt-merge-msg).

Before this change:

  merging refs/heads/a into refs/heads/master

After:

  Merge branch 'a'

Plurals, "into" and joining by "," and "and" also work.

The strings are externalized into the root resource bundles.
The resource bundles are stored under the new "resources" source
folder to get proper maven build.

Strings from tests are, in general, not externalized. Only in
cases where it was necessary to make the test pass the strings
were externalized. This was typically necessary in cases where
e.getMessage() was used in assert and the exception message was
slightly changed due to reuse of the externalized strings.

This is a simple HTTP server that provides the minimum server side
support required for dumb (non-git aware) transport clients.

We produce the info/refs and objects/info/packs file on the fly
from the local repository state, but otherwise serve data as raw
files from the on-disk structure.

In the future we could better optimize the FileSender class and the
servlets that use it to take advantage of direct file to network
APIs in more advanced servlet containers like Jetty.

Our glue package borrows the idea of a micro embedded DSL from
Google Guice and uses it to configure a collection of Filters
and HttpServlets, all of which are matched against requests using
regular expressions.  If a subgroup exists in the pattern, it is
extracted and used for the path info component of the request.
