rPc9c4dc1d9b01: Config - add setup checks for minimum and "bad" versions of VCS software.
Summary

Fixes T3046. Git has no minimum or bad versions; svn has no minimum and the bad version of 1.7.1, and mercurial has a minimum of 1.9 and bad versions 2.2 and 2.1. These error messages are specific about the problem but do not include the details as to what specifically is bad about a given version. I don't think that's really necessary - the details don't help solve the problem and its probably booooooring at best to the average user. The details about a bad version are included in the code however.

Test Plan

hardcoded a VCS array to let me test all the VCS stuff. added some phlog() calls to make sure the VCS version parsing stuff was working correctly relative to the version(s) on my system. played around with setting minimum versions and bad versions and saw good results depending on what I set.

Consider mapping these to a reason string to help us remember what's going on and users understand why the version is bad.

111

e.g., The reason for 2.1 is "This version of Mercurial returns a bad exit code after a successful pull."

119

Use version_compare() to deal with stuff like "10.1.1" being a larger version than "2.0.0" even though the string has a smaller alphabetic value.

updates... I wrote the "why" notes but I did not expose them to the user per my reasoning in the diff summary.
