[PATCH v2 0/4] Add Travis CI support

From: Lars Schneider <redacted>

diff to v1:
* improve readabilty of Travis "before_script" section
* make OS X Perforce brew robust against changing Perforce builds [1]
* add a prereq to detect OS X in tests
* fix t9815 git-p4-submit-fail test case on OS X
* disable t9819 git-p4-case-folding test on OS X

Thanks Junio for the feedback. You are right, I should have fixed the failing
tests in the first place. With this patch all tests pass on Linux and OS X:
https://travis-ci.org/larsxschneider/git/builds/83575208

In a subsequent patch I plan to:
* add cvs to run t94?? tests
* add svn to run t91?? tests
* add apache to run 5539, 5550, and 5561
* investigate if it is possible to run t1509 root worktree test
* investigate if it is possible to add jgit to run t5310

Plus I have the following questions:
* Can you explain to me how the t7006 page tests should be executed?
* Should we enable EXPENSIVE, CLONE_2GB, and USE_LIBPCRE flag?

Thanks,
Lars

[1] This is a workaround. I am in contact about the issue with the homebrew
maintainers and maybe we can make this easier soon:
