revset: avoid demandimport bug
Apparently the "import x as xy" doesn't manage to update xy in the
current scope's dictionary after load, which causes nodemod.nullrev to do a huge amount of demandload magic in the inner loop.

parsers: use base-16 trie for faster node->rev mapping
This greatly speeds up node->rev lookups, with results that are
often user-perceptible: for instance, "hg --time log" of the node
associated with rev 1000 on a linux-2.6 repo improves from 0.3
seconds to 0.03. I have not found any instances of slowdowns.
The new perfnodelookup command in contrib/perf.py demonstrates the
speedup more dramatically, since it performs no I/O. For a single
lookup, the new code is about 40x faster.
These changes also prepare the ground for the possibility of further
improving the performance of prefix-based node lookups.

graphlog: fix --follow-first --rev combinations
This solves a similar problem than the previous --follow/--rev patch. This time
we need changelog.ancestors()/descendants() filtering on first parent.
Duplicating the code looked better than introducing keyword arguments. Besides,
the ancestors() version was already implemented in follow() revset.

graphlog: fix --follow --rev combinations
The previous behaviour of --follow was really a subset of what is really
happening in log command:
- If --rev is not passed, default to '.:0'
- Resolve --rev into a revision list "revs"
- Set the starting revision to revs[0]
- If revs[1] > revs[0] keep descendants(revs[0]) in revs, otherwise keep
ancestors.

graphlog: pass changesets to revset.match() in changelog order
Running:
$ time hg debugrevspec 'user(mpm)' | wc
on Mercurial repository takes 1.0s with a regular version and 1.8s if
commands.debugrevspec() is patched to pass revisions to revset.match() from tip
to 0.
Depending on what we expect from the revset API and caller wisdom, we might
want to push this change in revset.match() later.

graphlog: refactor revset() to return revisions
When --follow and --rev are passed, --follow actual behaviour depends on the
input revision sequence defined by --rev. If --rev is not passed, the default
revision sequence depends on the presence of --follow. It means the revision
sequence generation is part of log logic and must be wrapped. The issue
described above is fixed in following patches.

store: speed up read and write of large fncache files
In my tests of an fncache containing 300,000 entries, this improves
read time from 567ms to 307, and write time from 1328ms to 533.
These numbers aren't so great, since the fncache file is only 17MB
in size, but they're an improvement.

revset: add "matching" keyword
This keyword can be used to find revisions that "match" one or more fields of a
given set of revisions.
A revision matches another if all the selected fields (description, author,
branch, date, files, phase, parents, substate, user, summary and/or metadata)
match the corresponding values of those fields on the source revision.
By default this keyword looks for revisions that whose metadata match
(description, author and date) making it ideal to look for duplicate revisions.
matching takes 2 arguments (the second being optional):
1.- rev: a revset represeting a _single_ revision (e.g. tip, ., p1(.), etc)
2.- [field(s) to match]: an optional string containing the field or fields
(separated by spaces) to match.
Valid fields are most regular context fields and some special fields:
* regular fields:
- description, author, branch, date, files, phase, parents,
substate, user.
Note that author and user are synonyms.
* special fields: summary, metadata.
- summary: matches the first line of the description.
- metatadata: It is equivalent to matching 'description user date'
(i.e. it matches the main metadata fields).
Examples:
1.- Look for revisions with the same metadata (author, description and date)
as the 11th revision:
hg log -r "matching(11)"
2.- Look for revisions with the same description as the 11th revision:
hg log -r "matching(11, description)"
3.- Look for revisions with the same 'summary' (i.e. same first line on their
description) as the 11th revision:
hg log -r "matching(11, summary)"
4.- Look for revisions with the same author as the current revision:
hg log -r "matching(., author)"
You could use 'user' rather than 'author' to get the same result.
5.- Look for revisions with the same description _AND_ author as the tip of the
repository:
hg log -r "matching(tip, 'author description')"
6.- Look for revisions touching the same files as the parent of the tip of the
repository
hg log -r "matching(p1(tip), files)"
7.- Look for revisions whose subrepos are on the same state as the tip of the
repository or its parent
hg log -r "matching(p1(tip):tip, substate)"
8.- Look for revisions whose author and subrepo states both match those of any
of the revisions on the stable branch:
hg log -r "matching(branch(stable), 'author substate')"

ui: optionally quiesce ssl verification warnings on python 2.5
Some platforms, notably Plan 9 from Bell Labs are stuck on older
releases of Python. Due to restrictions in the platform, it is not
possible to backport the SSL library to the existing Python port.
This patch permits the UI to quiesce SSL verification warnings by
adding a configuration entry named reportoldssl to ui.

scmutil: speed up revrange
This improves the performance of "hg log -l1" from 0.21 seconds to

Ideally we could use xrange instead of range on the most common
path, and thus avoid a ton of allocation, but xrange doesn't support
slice-based indexing.

parsers: fix a memleak, and add a clearcaches method to the index
This change also fixes a nasty memory leak: previously, self->caches

The new clearcaches method lets us benchmark with finer granularity,
as it lets us separate the cost of loading a revlog index from those
of populating and accessing the cache data structures.
