Summary:
Re-implement the `findcommonheads` logic using `changelog` APIs that are going
to have native support from Rust.
This decouples from revlog-based Python DAG logic, namely `dagutil.revlogdag`,
and `ancestor.incrementalmissingancestors`, unblocking Rust DAG progress, and
cleans up the algorithm to not use revision numbers.
The core algorithm is unchanged. The sampling logic is simplified and tweaked
a bit (ex. no 'initial' / 'quick initial' special cases). The debug and
progress messages are more verbose, and variable names are chosen to match
the docstrings.
I improved the doc a bit, and added some TODO notes about where I think can be
improved.

Summary:
Enables treemanifest for about 100 more tests. To make them pass I had
to expose the gettreepack capability from peers, which just works, and enable
treeonly and sendtrees by default in the tests, which I probably should've done
before anyway.

Summary:
An earlier change (D21394302) made discovery sampling use the most
recent commits. This ended up not being correct since if the requested sample
did not find any hits then the unknown set would not be reduced and the next
requested set would not change, resulting in an infinite loop.
The goal of the original diff was to ensure master was in the initial sample set
so we didn't have to inspect a bunch of really old commits. Let's go back to
random sampling, but manually insert master into the initial set.
In the long-term we should throw away all this code and use something similar to
discovery.fastdiscovery instead which just relies on the public heads.

Summary:
This enforces certain selective pull logic in core. Namely, rewrite `pull -r X`
to `pull -r X -B master`.
Unlike selectivepull in remotenames, `pull` (pulls everything) won't be
rewritten to `pull -B master` (which pulls less commits and names).
Therefore this change always adds more commits to pull, and therefore should not
break existing users. Eventually we want the "not pulling everything" behavior,
but right now this just fixes `pull -r X` to also update important remote names.

Summary:
This diff marks **ALL** mercurial tests requiring Python 2 feature.
After you fixes some tests, simply remove the `py2` feature requirement and that tests will be continuously run after your diff is landed.
To bypass this feature requirement, run the tests command with `HGTEST_FORCE_PY2=1`. For example:
```
HGTEST_FORCE_PY2=1 buck test //eden/scm/tests:hg_run_tests
```
or
```
HGTEST_FORCE_PY2=1 python run-tests.py
```
----
Basically this diff are created with the following commands:
```
$ sed -i 's/import feature\(.*\)$/import feature\1\n\nfeature.require(["py2"])/' test-*-t.py
$ sed -i '1s/^/#require py2\n/' test-*.t
$ ls | grep -P "^test.*(?<\!-t)\.py$" > list && vim -p $(cat list)
# manually adding feature requires for these Python tests.
```
(Note: this ignores all push blocking failures!)
