6551ea8245 Detect missing 'svn', 'hg' and 'git' during setup
Summary:
These are a bit tricky because we don't want to require you to install a VCS you don't use just to use Phabricator. Test that repositories exist before performing the checks.

I'll couple this with additional checks during repository creation.

Test Plan: Changed binary names to nonexistent ones, verified setup issues raised properly.

e591ef4db9 Add setup checks for the availability of 'which' and 'diff' binaries
Summary:
Spent an hour or two helping a user figure this out. Make sure I never do that again.

If the webserver is configured with an empty or bogus PATH, binaries like 'which' and 'diff' (and 'git', and 'svn', etc.) may not be available. In most cases, this is fine, because we get an error like "sh: whatever-command not found", which is obvious to diagnose.

In the case of 'diff', we don't get this, because 'diff' is expected to exit with a nonzero code for differing files -- so we interpret the "sh: whatever-command not found" as "files differ" and then try to parse the empty output.

Explicitly check for 'which' (on Windows, 'where') and 'diff' during setup (I plan to refine the behavior around 'git', 'svn' and 'hg' at some point, but this is less pressing since the errors are trivial to support).

Test Plan: Faked failures on all modes, verified setup warnings look reasonable.
