Summary:
If we release a new version of Mercurial, we want to ensure that it's
builtin configs are used immediately. To do so, let's write a version number
into the generated config file, and if the version number doesn't match, we
force a synchronous regeneration of the config file.
For now, if regeneration fails, we just log it. In the future we'll probably
throw an exception and block the user since we want to ensure people are running
with modern configuration.

Summary:
Follow up from D21596758 - current logic of pushrebasing a merge is very
complicated. To prevent repo corruptions let's do a very simple validation -
generate hg changeset from a rebased bonsai changeset.
Given that generating hg changeset is an expensive operation let's do it only
after the first rebase attempt - otherwise we might risk constantly losing the
pushrebase race.

Summary:
Mononoke server is the only binary using plain `clap::App`, whilst all
other services use `MononokeApp`. The `MononokeApp` variant configures some
default arguments and provides consistent argument naming between binaries.
Update the server to use `MononokeApp` and add some logic to allow passing
either `--config_path` or `--mononoke-config-path` until we remove all uses of
`--config-path`.

Summary:
During clone the hgrc.dynamic file doesn't exist and doesn't even have
a place for us to generate it to. Let's instead generate and apply the config in
memory.
In the future, if generate fetches data from the network, this will mean clone
would depend on the network, since if generate fails the clone would fail. In
some situations this is desirable, since users shouldn't be cloning without our
approved configs, but if it causes problems we could probably tweak generate to
support an offline mode.

Summary:
With `HGPLAINEXCEPT=color`, colors should still be enabled if the terminal is
capable of supporting them and output is to the terminal.
Currently this doesn't work if `--color=auto` (the default), as
`color._modesetup` uses `ui.formatted` to check if the output is a terminal,
and thus has colors available, but this is `False` for all `HGPLAIN` modes.
Instead, add a new method to `ui` that checks whether `fout` is a terminal, and
use that for color autodetection.
This function also allows us to add `HGPLAINEXCEPT=pager` as we can use
that in the same way.

Setting the fake pager in the pager test doesn't work on Windows.
For some reason, the `pager.pager=C:/path/to/python.exe C:/path/to/test/fakepager.py` triggers
some kind of PATH translation code that results in `setconfig.py` receiving
`pager.pager=C;C:\\path\\to\\python.exe C;C:\\path\\to\\test\\fakepager.py` as its
argument. This is clearly invalid, so the test fails with messages like
`'C' is not recognized as an internal or external command`.
Workaround this for now by setting the pager by appending directly to HGRCPATH.

Summary:
Before this change, pull_shallow only calls setuprepo if the remotefilelog
requirement is not in repo. With D21011401, the remotefilelog requirement
will be added by clone.py and pull_shallow can skip calling setuprepo, causing
the pull code paths to write file logs (and fail).
Change the pull_shallow to always call `setuprepo` to solve the issue.
The final fix is probably moving more remotefilelog related clone logic to core.
Right now I just did the minimal change to fix things.

Summary:
This is the fix that might be hard to explain.
First, why we need `generate_additional_bonsai_file_changes()` function at all.
TL;DR is to fix pushrebasing of a diamond merge commit. Merge bonsai changeset
must have a file change entry if p1 and p2 has the same file with different
content, and when merge commit is pushrebased we need to preserve this property.
more details are in D18065013 and in the comments.
Secondly, what was wrong with generate_additional_bonsai_file_changes. While it
was technically correct (i.e. it was producing valid bonsai changeset) it had
an unexpected side-effect for non-diamond merges (e.g. repo imports). It was
adding all changed files between root and onto commit (i.e. all changed files
from commits over which it was rebased). This in turn leads to unnecessary
push failures with "conflicts" errors.
Thirdly, why it was wrong. generate_additional_bonsai_file_changes
a) finds all files changed between onto and root (see comments for more details about onto
and root),
b)then finds those that needs to be added in the pushrebase merge bonsai changeset.
The problem was in step b). It needed to check which files exists in merge
parent but instead it checked which files exists in merge commit itself.
This is because merge commit itself cannot change any of the files that were changed between root
and onto - in that case we get a pushrebase conflict. So all the files come
either from root commit or from another parents. And the entry can become
"stale" only if it existed in one of the parents and later was changed between
root and onto.
