rust-nodemap: input/output primitives

These allow to initiate a `NodeTree` from an immutable opaque
sequence of bytes, which could be passed over from Python
(extracted from a `PyBuffer`) or directly mmapped from a file.

Conversely, we can consume
a `NodeTree`, extracting the bytes that express what
has been added to the immutable part, together with the
original immutable part.
This gives callers the choice to start a new Nodetree.
After writing to disk, some would prefer to reread for
best guarantees (very cheap if mmapping), some others will
find it more convenient to grow the memory that was considered
immutable in the `NodeTree` and continue from there.

This is enough to build examples running on real data and
start gathering performance hints.

'''command to view revision graphs from a shell (DEPRECATED)

The functionality of this extension has been include in core Mercurial
since version 2.3. Please use :hg:`log -G ...` instead.

This extension adds a --graph option to the incoming, outgoing and log
commands. When this options is given, an ASCII representation of the
revision graph is also shown.
