[PATCH 0/4] Run test suite without dashed commands in PATH

This patch series runs the test suite without the dashed commands
in the PATH.  This improves the usefulness of the test suite
as examples of how to do things, and more importantly,
minimizes any possibility of regressions in bindir-installed
scripts that might prevent them from working in a standard
install where most dashed commands are not in the PATH (git-cvsserver
was broken in this way until Sep 2009: d2feb01aa5).

The scripts in the "test-bin" directory that patch 3 creates
can also be useful for manually testing a build of git without
installing it; you typically don't need to set any environment
variables (except maybe PATH) for the test-bin scripts to use
the build properly.

Trivial note: This is a cleaned up resend of part of a hodgepodge
cvsserver patch series that I sent last January.

---------

By the way, has anyone considered the possibility of splitting
up the large directory at the top of the git source tree?  I
suspect that no one is interested, or it would have been done
already, but I thought I would mention it anyway.  Perhaps split
off separate directories for libgit.a, builtins, other C-based
excutables, test support executables, scripts, output execdir, and
output intermediate (object) files for each of the other
directories.  Or some subset of these.
