procutil: use unbuffered stdout on Windows
Windows doesn't support line buffering, treating it as fully buffered. This
causes output of slow commands to stutter. We use unbuffered instead.
graft: introduce --abort flag to abort interrupted graft
This patch introduces a new --abort flag to `hg graft` command which aborts an
interrupted graft and rollbacks to the state before graft.
The behavior when some of grafted changeset get's published while interrupted
graft or we have new descendants on grafted changesets is same as that of rebase
which is warn the user, don't strip and abort the abort the graft.
Tests are added for the new flag.

templater: fix truth testing of integer 0 taken from a list/dict
Broken at

an integer 0 has to be truthy for backward compatibility.
formatter: look for template symbols from the associated name
Otherwise symbolsused() would fail if a named template is specified with -T.
