localrepo: clear _filecache earlier to really force reloading (issue3462)
ce0ad184f489 attempted to force the filecaches in localrepo to reload
everything after a rollback. But simply clearing _filecache isn't enough,
invalidate() needs to be called before/after. localrepo._rollback calls
invalidate() already, so we clear the map right afterwards which ensures
everything will be reread.

cleanup: use the deque type where appropriate
There have been quite a few places where we pop elements off the
front of a list. This can turn O(n) algorithms into something more
like O(n**2). Python has provided a deque type that can do this
efficiently since at least 2.4.
As an example of the difference a deque can make, it improves
perfancestors performance on a Linux repo from 0.50 seconds to 0.36.

match: make 'match.files()' return list object always
'exact' match objects are sometimes created with a non-list 'pattern'
argument:
- using 'set' in queue.refresh():hgext/mq.py
match = scmutil.matchfiles(repo, set(c[0] + c[1] + c[2] + inclsubs))
- using 'dict' in revert():mercurial/cmdutil.py (names = {})
m = scmutil.matchfiles(repo, names)
'exact' match objects return specified 'pattern' to callers of
'match.files()' as it is, so it is a non-list object.
but almost all implementations expect 'match.files()' to return a list
object, so this may causes problems: e.g. exception for "+" with
another list object.
this patch ensures that '_files' of 'exact' match objects is a list
object.
for non 'exact' match objects, parsing specified 'pattern' already
ensures that it it a list one.

parsers: cache the result of index_headrevs
Although index_headrevs is much faster than its Python counterpart,
it's still somewhat expensive when history is large. Since headrevs
is called several times when the tag cache is stale or missing (e.g.
after a strip or rebase), there's a win to be gained from caching
the result, which we do here.

revlog: switch to a C version of headrevs
The C implementation is more than 100 times faster than the Python
version (which is still available as a fallback).
In a repo with 330,000 revs and a stale .hg/cache/tags file, this
patch improves the performance of "hg tip" from 2.2 to 1.6 seconds.

graphlog: turn getlogrevs() into a generator
This improves the poor "time to first changeset" compared to the
original log command. When running:
$ hg log -u user
log will enumerate the changelog and display matching revisions when
they are found. But:
$ hg log -G -u user
will first find all revisions matching the user then start to display
them.
Initially, I considered turning revset.match() into a generator. This is
doable but requires a fair amount of work. Instead,
cmdutil.increasingwindows() is reused to call the revset matcher
repeatedly. This has the nice properties of:
- Let us reorder the windows after filtering, which is necessary as the
matcher can reorder inputs but is an internal detail not a feature.
- Let us feed the matcher with windows in changelog order, which is good
for performances.
- Have a generator designed for log-like commands, returning small
windows at first then batching larger ones.
I feel that calling the matcher multiple times is correct, at least with
the revsets involved in getlogrevs() because they are:
- stateless (no limit())
- respecting f(a|b) = f(a) | f(b), though I have no valid argument about
that.
Known issues compared to log code:
- Calling the revset matcher multiple times can be slow when revset
functions have to create expensive data structure for filtering. This
will be addressed in a followup.
- Predicate combinations like "--user foo --user bar" or "--user foo and
--branch bar" are inherently slower because all input revision are
checked against the first condition, then against the second, and so
forth. log would enumerate the input revisions once and check each of
them once against all conditions, which is faster. There are solutions
but nothing cheap to implement.
