revlog._chunks: inline getchunk
We do this in a somewhat hacky way, relying on the fact that our sole caller
preloads the cache right before calling us. An upcoming patch will make this
more sensible.
For a 20 MB manifest with a delta chain of > 40k, perfmanifest goes from 0.49
seconds to 0.46.

revlog.revision: fix cache preload for inline revlogs
Previously the length of data preloaded did not account for the interleaved io
contents. This meant that we'd sometimes have cache misses in _chunks despite
the preloading.
Having a correctly filled out cache will become essential in an upcoming patch.

revlog: add a fast method for getting a list of chunks
This moves _chunkraw into the loop. Doing that improves revlog decompression --
in particular, manifest decompression -- significantly. For a 20 MB manifest
which is the result of a > 40k delta chain, hg perfmanifest improves from 0.55
seconds to 0.49 seconds.

perfmanifest: allow and require passing in a rev
Previously perfmanifest would only test tip.

perfmanifest: fix cache invalidation
The manifest cache is now stored in _mancache. The revlog cache is still stored
in _cache.

bundle: fix performance regression when bundling file changes (issue4031)
Somewhere before 2.7, a change [ec896f9e8894] was committed that
entailed a large performance regression when bundling (and therefore
remote cloning) repositories. For each file in the repository, it would
recompute the set of needed changesets even though it is the same for
all files. This computation would dominate bundle runtimes according to
profiler output (by 10x or more).

revset: fix wrong keyword() behaviour for strings with spaces
Some changesets can be wrongly reported as matched by this predicate
due to searching in a string joined with spaces and not individually.
A test case added, which fails without this fix.
