[PATCHv2 00/21] git p4: work on cygwin

[Pete Wyckoff <pw@padd.com>]

Junio and Hannes:  thanks for the comments four months ago; I've
been slow getting back to this.  I incorporated all your
suggestions.

Junio: this merges okay with Brandon's v2.4 support series.

This series fixes problems in git-p4, and its tests, so that
git-p4 works on the cygwin platform.

See the wiki for info on how to get started on cygwin:

    https://git.wiki.kernel.org/index.php/GitP4

Testing by people who use cygwin would be appreciated.  It would
be good to support cygwin more regularly.  Anyone who had time
to contribute to testing on cygwin, and reporting problems, would
be welcome.

There's more work requried to support msysgit.  Those patches
are not in good enough shape to ship out yet, but a lot of what
is in this series is required for msysgit too.

These patches:

    - fix bugs in git-p4 related to issues found on cygwin

    - cleanup some ugly code in git-p4 observed in error paths while
      getting tests to work on cygwin

    - simplify and refactor code and tests to make cygwin changes easier

    - handle newline and path issues for cygwin platform

    - speed up some aspects of git-p4 by removing extra shell invocations

Changes from v1:

    http://thread.gmane.org/gmane.comp.version-control.git/206557

    - Addressed comments from Junio and Hannes:

	- Removed "git p4: fix error message when "describe -s" fails";
	  it was fixed as part of 18fa13d (git p4: catch p4 describe
	  errors, 2012-11-23), with messages like "p4 describe -s ...
	  failed".

	- Removed extranneous "grep -q" in "git p4: generate better
	  error message for bad depot path".

	- Added "git p4 test: avoid loop in client_view" after a
	  suggestion from Junio.

	- Made the test-path-utils removal explicit.

	- Modify the chmod test to use test_chmod, and verify at
	  least the p4 bits on cygwin, although not the filesystem.

    - Retested on latest cygwin
