revset: speedup matching() by first matching fields that take less time to
match
This patch sorts the fields that are passed to the matching function so that it
always starts by matching those fields that take less time to match.
Not all fields take the same amount of time to match. I've done several
measurements running the following command:
hg --time log -r "matching(1, field)"
on the mercurial repository, and where 'field' was each one of the fields
accepted by match. In order to avoid the print overhead (which could be
different for different fields, given the different number of matches) I used a
modified version of the matching() function which always returns no matches.
These tests showed that different fields take wildly different amounts of time
to match. Particulary the substate field takes up to 25 seconds to match on my
machine, compared to the 0.3 seconds that takes to match the phase field or the
2 seconds (approx) that takes to match most fields. With this patch, matching
both the phase and the substate of a revision takes the same amount of time as
matching the phase.
The field match order introduced by this patch is as follows:
phase, parents, user, date, branch, summary, files, description, substate
An extra nice thing about this patch is that it makes the match time stable.

revset: speedup matching() by stopping the match early if a field does not match
Rather than getting all the fields that are being matches from every revision
and then comparing them to those of the target revision, compare each field one
by one and stop the match as soon as there is a match failure.
This can greatly reduce the match time when matching multiple fields.
The impact on match time when matching a single field seems negligible
(according to my measurements).

fileset: add "subrepo" fileset symbol
This new fileset symbol returns a list of subrepos whose paths match a given
pattern. If the argument has no pattern type set, an exact
match is performed.
If no argument is passed, return a list of all subrepos.

largefiles: fix cat for largefiles (
issue3352)
This is a fix to largefiles so that 'hg cat' will work correctly when a
largefile is specified.
As per discussion on Issue 3352:
1) The file will be printed regardless if it is binary or large.
2) The file is downloaded if it is not readily available (not found in
the system cache), so that it can be printed. If the download fails,
then we abort.
