sparse-revlog: add a `index_get_length` function in C
We are about to implement a native version of `slicechunktodensity`. For
clarity, we introduce the helper functions first. This new function provides
an efficient way to retrieve some of the information needed by
`slicechunktodensity`.

perf: add --clear-revlog flag to branchmapload
Having the changelog index already loaded when loading the branchmap can have a
large impact on performance.
Example runs (large private repository):
hg perfbranchmapload -f base
! wall 0.116722 comb 0.120000 user 0.110000 sys 0.010000 (best of 59)
hg perfbranchmapload -f base --clear-revlogs
! wall 0.258246 comb 0.230000 user 0.220000 sys 0.010000 (best of 31)

perf: introduce a function to fully "unload" a changelog
The function remove various attributes and caches related to changelog.
This is getting a common requirement.

perf: use an explicit function in perfbranchmapload
This make things clearer.

perf: update function name to match `perfbranchmapload` command
Having function with the same name as the command is simpler.

context: floor adjustlinkrev graph walk during copy tracing
The `_adjustlinkrev` method gains an optional "stoprev" argument. The linkrev
adjustment will give up once this floor is reached. The relevant functions
using `_adjustlinkrev` are updated to pass an appropriate value in the copy
tracing code.
In some private repository, about 10% of the status call triggered the
pathological case addressed by this change. The speedup varies from one call
to another, the best-observed win is moving from 170s to 11s.
The effect of this change can be seen in the public pypy repository, running the
following command:
hg perftracecopies --source 83c9ff0c0206 --destination 59c79103d5b0
before: 3.401753 seconds
after: 2.634897 seconds (-23%)

context: split `introrev` logic in a sub function
We want to add a mechanism to stop iteration early associated to intro rev early
in some case. However, it does not make sense to expose it in the public
`filectx` API. So we split the code into an internal method instead.
