update 5.1.2 with latest bugfix

evolve: have a stable manifest content when solving bumped We cannot really use iteritems here.

evolve: change config option name I forgot to amend...

config: allow disabling commands Now that upstream Mercurial has multiple options for obsolete configuration, we can allow enabling and disabling of evolve commands.

inhibit: Add some inhibition clearing mechanism We do not want to keep inhibition marker around for ever. So we are removing the one applying on public changeset.

add a 'inhibit' extension This extension will be used to reduce the scope of evolve in order to make some of its features available to the mass earlier. See extension documentation for details.

tests: use 'wget' instead of 'curl' for Windows compatibility The whole test suite now runs without skips, and the only two failures are a bookmark cache issue in test-prune.t, and a local output vs remote output reordering when pushing to ssh. The latter anyway is a core problem.

tests: import killdaemons.py from Mercurial 1cfded2fa1a9 This contains updated functionality to kill the server process on Windows, which is needed to run the test-*server.t tests. This version requires the pids to be passed as an argument instead of via $DAEMON_PIDS.

prune: add --keep to not touch the working copy In order to more closely emulate strip, lets add --keep to leave the working copy untouched when we do our prune.

strip: add the option for wrapping the strip command Adds an experimental option for wrapping the existing strip command and replacing its functionality with prune. It currently doesn't handle the --keep case, but an upcoming patch will address that.
