nodemap: introduce an option to use mmap to read the nodemap mapping

The performance and memory benefit is much greater if we don't have to copy all
the data in memory for each information. So we introduce an option (on by
default) to read the data using mmap.

This changeset is the last one definition the API for index support nodemap
data. (they have to be able to use the mmaping).

Below are some benchmark comparing the best we currently have in 5.3 with the
final step of this series (using the persistent nodemap implementation in
Rust). The benchmark run `hg perfindex` with various revset and the following
variants:

Before:

 * do not use the persistent nodemap
 * use the CPython implementation of the index for nodemap
 * use mmapping of the changelog index

After:

 * use the MixedIndex Rust code, with the NodeTree object for nodemap access
   (still in review)
 * use the persistent nodemap data from disk
 * access the persistent nodemap data through mmap
 * use mmapping of the changelog index

The persistent nodemap greatly speed up  most operation on very large
repositories. Some of the previously very fast lookup end up a bit slower because
the persistent nodemap has to be setup. However the absolute slowdown is very
small and won't matters in the big picture.

Here are some numbers (in seconds) for the reference copy of mozilla-try:

On smaller repositories, the cost of nodemap related operation is not as big, so
the win is much more modest. Yet it helps shaving a handful of millisecond here
and there.

(Issue3303)
Check that remote secret changeset are ignore when checking creation of remote heads

We add a secret head into the push destination. This secret head shadows a
visible shared between the initial repo and the push destination.

  $ hg up -q 4 # B'
  $ mkcommit Z --config phases.new-commit=secret
  test-debug-phase: new rev 5:  x -> 2
  test-hook-close-phase: 2713879da13d6eea1ff22b442a5a87cb31a7ce6a:   -> secret
  $ hg phase .
  5: secret

We now try to push a new public changeset that descend from the common public
head shadowed by the remote secret head.

  $ cd ../initialrepo
  $ hg up -q 6 #B'
  $ mkcommit I
  test-debug-phase: new rev 8:  x -> 1
