test-hardlinks: stabilize for Windows This broke in c2cb0de25120, which breaks hardlinks when the executable bit is toggled.

releasenotes: add more tests for formatting and merging of release notes

releasenotes: command to manage release notes files Per discussion on the mailing list, we want better release notes for Mercurial. This patch introduces an extension that provides a command for producing release notes files. Functionality is implemented as an extension because it could be useful outside of the Mercurial project and because there is some code (like rst parsing) that already exists in Mercurial and it doesn't make sense to reinvent the wheel. The general idea with the extension is that changeset authors declare release notes in commit messages using rst directives. Periodically (such as at publishing or release time), a project maintainer runs `hg releasenotes` to extract release notes fragments from commit messages and format them to an auto-generated release notes file. More details are explained inline in docstrings. There are several things that need addressed before this is ready for prime time: * Moar tests * Interactive merge mode * Implement similarity detection for individual notes items * Support customizing section names/titles * Parsing improvements for bullet lists and paragraphs * Document which rst primitives can be parsed * Retain arbitrary content (e.g. header section/paragraphs) from existing release notes file * Better error messages (line numbers, hints, etc)

packagelib: use LANGUAGE=C for "hg version" If "hg version" does not contain "version" (e.g. Japanese), $hgversion was empty and rpmbuild failed.

rpms: add hgdemandimport in files

rpms: remove '%if "%{?pythonver}" != "2.4"' Mercurial requires python >= 2.7.

obsstore: do not load all markers to detect duplication This will make duplication detection something like O(newmarkers) instead of O(obsstore).

clonebundles: reference correct config option This option is no longer experimental.

filestat: move __init__ to frompath constructor We're going to add a `fromfp` constructor soon, and this also allows a filestat object for a non-existent file to be created.

test-dirstate-race: ensure that a isn't in the lookup set at the end We're going to rely on this in upcoming patches.

hghave: add test for whether fsmonitor is enabled This uses the HGFSMONITOR_TESTS environment variable that fsmonitor-run-tests.py adds.

tests: add a wrapper to run fsmonitor tests This script does a bunch of non-trivial configuration work: in particular, it sets up an isolated instance of Watchman which isn't affected by global state and can be torn down on completion. This script also sets the HGFSMONITOR_TESTS environment variable, which hghave will use in the next patch to allow gating on whether fsmonitor is enabled. With fsmonitor enabled, there appear to be a number of failures in the test suite. It's not yet clear to me why they're happening, but if someone would like to jump in and fix some of them I hope this will be helpful for that.

setdiscovery: improves logged message The 'srvheads' list contains all server heads including the common ones. We adjust 'ui.log' message to provide more useful information about server heads locally unknown. The performance impact of turning the list to set is negligible (about 1e-4s) compared to the rest of the discovery cost, so I'm taking the easy path.

tests: handle variation between pure and normal output in annotate --skip I'm pretty sure that both results are valid, depending on how you slice the edits.
