Summary:
The Python 3 email library internally stores the message as text, even
though our input and requested output is bytes. Let's make our own wrapper
around the parser to use ascii surrogateescape encoding so we can get the
actual bytes out later and not get universal newlines.
Based off the upstream 7b12a2d2eedc995405187cdf9a35736a14d60706,
which is basically a copy of the BytesParser implementation (https://github.com/python/cpython/blob/3.8/Lib/email/parser.py) with
newline=chr(10) added.

Once we discover that the (small) repo we import into push-redirects (D23158826 (d3f3cffe13)) to a large repo,
we want to import into the large repo first, then backsync into the small one (see previous diff summary).
The aim of this diff is to setup the variables (e.g. bookmarks) needed for importing into
the large repo first before backsyncing the commits into the small repo.
Next step: add functionalities to control how we backsync from large repo to the small repo

Summary:
When updating to the null commit, the logic that computes the update
distance was broken. The null commit is pre-resolved to -1, which when passed to
a revset raw gets resolved as the tip commit. In large repositories this can
take a long time and use a lot of memory, since it's computing the difference
between tip and null.
Let's fix it to not pass the raw rev number, and also to handle the case of a 0
distance update.

Summary:
If there are too many heads, the current `descendants` algorithm would visit
all "old" heads. For example, with this graph:
head9999 (N9999)
/
Z (master)
:
: (many heads)
:/
: head2 (N2)
:/
C head1 (N1)
|/
B head0 (N0)
|/
A
`A::head9999` or `Z::head9999` will visit N0, N1, ..., N9999, because
`descendands_up_to` is provided with `max_id = N9999` and Z as a vertex in the
master group, is before N0 in non-master. The current algorithm also means
`descendands_up_to` gets linearly slower as the user uses the repo more, which
is quite undesirable.
This diff changes `descendands_up_to` to take an `ancestors` set, which is
`::head9999` in this case, and iterate non-master flat segments in it. So it
will skip N0 to N9998 directly by finding the N9999 flat segment and only use
it. The number of heads will have a smaller impact on performance.
Another slowness is `draft::draft_heads`, if there are too many `draft_heads`,
the internal calculation of `::draft_heads` can be slow. Optimize it by
limiting `draft_heads` to `draft:`. Practically this affects `y::` revset as
`y::` is translated to `y::visible_heads` and `visible_heads` can be large.
`cargo bench --bench dag_ops -- '::-master'` shows significant difference:
Before:
range (master::draft) 18.112 s
range (recent_draft::drafts) 2.594 s
After:
range (master::draft) 72.542 ms
range (recent_draft::drafts) 14.932 ms
In my fbsource checkout there were 20k+ heads. The improvement of
`master::recent_draft` (`x::y`) is pretty visible, and `y::` is also improved:
% lhg debugbenchmarkrevsets -m -x 'p1(min(7e8c86ae % master))' -Y 'draft() & 7e8c86ae' -e 'x::y' -e 'y::' --no-default
