extensions: add "uipopulate" hook, called per instance, not per process
In short, this is the "reposetup" function for ui. It allows us to modify
ui attributes without extending ui.__class__. Before, the only way to do
that was to abuse the config dictionary, which is copied across ui instances.
See the next patch for usage example.

hgweb: load globally-enabled extensions explicitly
Before, extensions were loaded as a side effect of hg.repository() if the
hgweb was executed as a CGI/WSGI. I want to make it explicit so that another
ui hook can be inserted after extensions.loadall().

tests: disable remotefilelog on Windows
I've spent a non trivial amount of time trying to eliminate the test errors, but
it's looking like this is pretty dependent on Unix support. For example, there
are attempts to delete open files, and uses of threads that report I/O attempts
on closed files. (Maybe this is a race condition? Don't we usually use
processes as workers on Windows?)
In any event, I don't want real new errors elsewhere to be masked by these known
problems.
For some reason $CACHEDIR is reported as missing in test-remotefilelog-repack.t,
but it actually exists in the hgcloneshallow call inside
shallowutil.mkstickygroupdir(). By the time the process exits, it's gone. I
don't see it being removed by code that calls 'rmdir' or 'remove' in the
extension itself.

perf: run 'setup' function during stub run
The benchmarked function might need the content of the setup to be run in order

perf: fallback to subset if ondisk cache is missing in perfbranchmapload
If there is no branchmap on disk for that filter, it means that the cache from
some subset's filter is relevant for this one. We look for it instead of
aborting.
That way it is much simpler to run the command in an automated way. We can now
add it to `test-contrib-perf.t`.

perf: prewarm the branchmap in perfbranchmapload
It is not very interesting to have the command randomly failing because the
branchmap for the tested filter happens to be cold. So we make sure to have a
valid up to date branchmap before going further.
The data might still be missing from disk if a subset was equivalent. See next
changeset for details and fix.

procutil: don't allow the main 'hg' script to be treated as the Windows exe
Previously, there were a handful of errors like this:
$ hg prefetch --repack
(running background incremental repack)
+ abort: %1 is not a valid Win32 application
+ [255]
CreateProcess() doesn't append .exe when `lpApplicationName` contains a path,
and a python script isn't directly executable.

branchmap: build the revbranchcache._namesreverse() only when required
On big repositories with a lot of named branches and that also increasing over
time, building of this dict can be expensive and shows up in profile.
For our internal repository, this saves ~0.05 seconds.
Thanks to Yuya for suggesting using util.propertycache() and
util.clearcachedproperty().

sparse-revlog: put the native implementation of slicechunktodensity to use
When possible, the C implementation of delta chain slicing will be used.
providing a large boost in performance for this operation.
To take a practical example of restoring manifest revision '59547c40bc4c' for
a reference NetBeans repository (using sparse-revlog). The media time of the
step `slice-sparse-chain` of `perfrevlogrevision` improve from 0.660 ms to
0.098 ms;
The full series move delta chain slicing from 1.120 ms to 0.098 ms;
Implementing _slicechunktosize into C would yield further improvements.
However, the performance seems good enough for now.

sparse-revlog: introduce native (C) implementation of slicechunktodensity
This is a C implementation of `_slicechunktodensity` in the
`mercurial/revlogutils/deltas.py` file.
The algorithm involves a lot of integer manipulation and low-level access to
index data. Having a C implementation of it raises a large performance
improvement. See later changeset in this series for details.
