Bug 1384396 - Detect Watchman Mercurial integration in configure; r=nalexander Configure now detects VCS info. Configure now detects Watchman. We can combine the two so configure can detect if Mercurial is configured with Watchman enabled. This commit does two things: 1) collects the Mercurial config so it is available to downstream checks 2) examines the config for presence and state of the fsmonitor extension We don't yet do anything with the fsmonitor state. But it should be useful soon. Also, the return value is kinda wonky. This will almost certainly be improved as soon as there is an actual consumer. MozReview-Commit-ID: HyHZ2X8VI0h
