check-code: allow tabs in heredoc

hgweb: rewrite `template = A and B or C` to be a proper ternary operator

fsmonitor: fsmonitor should send wlock notifications to watchman The fsmonitor extension should send state-enter and state-leave notifications to watchman when the wlock is acquired/release, respectively. This will allow watchman and watchman subscribers to customize behavior based on whether source control operations are occurring. Test Plan: Tested checkout, update and working copy changes with extension enabled. Differential Revision: https://phab.mercurial-scm.org/D1612

fsmonitor: remove watchman transaction and working copy change notifications Remove working copy change and transaction notifications. We were relying upon callbacks on transaction function. This caused issues with lock ordering. A different approach will be adopted in a subsequent commit. Differential Revision: https://phab.mercurial-scm.org/D1611

patch: catch unexpected case in _inlinediff If operation is neither 'diff.inserted' or 'diff.deleted', label and token won't be define. This patch explicitely catches that exception.

patch: reverse _inlinediff output for consistency

phases: drop the list with phase of each rev, always comput phase sets Change the C implementation of phasecache.loadphaserevs to provide only the sets for draft and secret phase as well as the number of revisions seen. Change the pure Python implementation of the same functino to compute the sets instead of the list of phases for each revision. Change phasecache.phase to check the phase sets and assume public if the revision is in neither draft nor secret set. This is computationally slightly more expensive. Change phasecache.getrevset for public() based queries to compute the set of non-matching revisions and return the result as filtered fullreposet. A shortcut is taken when no draft or secret revision exists. Bump the module version for the changed interface contract. Overall, this saves around 16 Bytes per revision whenever the phasecache is used, for the test case in issue5691 it is around 3MB. getrevset() for a large repository is around 13% slower here, that seems an acceptable trade off. Performance impact for phase() should be similar. Differential Revision: https://phab.mercurial-scm.org/D1606
