Summary:
When using the `debugedenimporthelper` subcommand that is part of `hg` itself
it is much more important to make sure that we don't try to use `stdout` as
the import communication mechanism.
The old `hg_import_helper.py` script more carefully set up its own `UI` object
to try and avoid ever printing any messages to `stdout`. However it isn't
easily possible to do this as part of the normal `hg` program. Therefore
abort the command if `hg debugedenimporthelper` is ever run without an
`--out-fd` argument.
This also helps avoid potentially confusing users by printing binary data to
stdout if they invoke accidentally `hg debugedenimporthelper` interactively in
a terminal.

Summary:
This starts to fix some of the `hg debugedenimporthelper` behavior and make it
work more like most other hg subcommands with respect to how it finds the hg
repository.
Previously the code was copied into hg largely as-is from an external script
that took the repository path as a separate argument. This resulted in
confusing behavior as it completely ignored the normal repository object
opened by `hg`.
This makes `debugedenimporthelper` honor the normal hg repo object if the
extra repository path argument is not specified.

This hardcodes several perftweaks configs that have been enabled for major FB
repos for months:
[perftweaks]
disablebranchcache = True
disablebranchcache2 = True
disableresolvingbranches = True
disableupdatebranchcacheoncommit = True
Practically, this means the branchmap is now just `{'default': heads}`. (i.e.
there are no named branches other than `default`), and branchcache is removed
(i.e. `.hg/cache` does not exist without clindex or in-repo tags).
This diff only makes easy-to-verify logic changes by assuming the configs and
removing dead code. Things can be further cleaned up. They will be done by
upcoming changes.
Most test changes are due to the fact that `.hg/cache` is no longer created.

Summary:
Context: in pushrebase replay job we run on Mononoke we also want to test our
hooks i.e. replay pushrebase requests that were denied on mercurial because of
a hook failure. The problem is that at the moment the only error message we have
is `prepushrebase.driver hook failed` (see xdb table `xdb.mononoke_production`,
query `select * from pushrebaserecording where pushrebase_errmsg like '%hook%'
limit 10;`). This error message tells us nothing, not even what hook failed.
To change it I suggest to make it possible for python hooks to raise HookAbort
and provide more information in the `hook_failure_reason` field.

Summary:
CommandError happens if there is an unknown command flag, or a required
argument is missing. The old behavior is to print an error message to
stderr, then start the pager with the command help printed to stdout.
There are 2 problems with that approach:
1. When using mosh, a long help text might flush the actual error to out of the
screen. The error message will be missed.
2. When captured in shell scripts, the help text printed to stdout would be
captured, which is almost always undesirable.
The actual motivation of this change is for 2. Zsh themes like bullet-train [1]
uses `hg id -b 2>/dev/null` and we'd like to remove `id -b` support. After that,
the command should not polluate stdout with help text.

It's possible that the non-mergedriver code path decides to create ("get") a
file, because it only exists in one side of the merge parents, while
mergedriver decides to remove that file. That makes the file exist in both

dirstate state.
Fix it by detecting the case and remove the conflicted files from the "g" list.

Rustls also builds on Windows without any special configuration, sidestepping the issues we've been having with OpenSSL in the Windows build.

Right now, the only thing initialized in the new module is `env_logger`.

encoding: alias cp65001 to utf-8 on Windows
As far as I can tell, cp65001 is the Windows name for UTF-8. I don't know
how different it is from the UTF-8, but Python 3 appears to have introduced
new codec for cp65001, so the alias is enabled only for Python 2.

This patch is untested, but hopefully fixes the following issue.
https://bitbucket.org/tortoisehg/thg/issues/5127/
More context:
Windows 10 Build 17035 (November 2017) introduced a
"Use Unicode UTF-8 for worldwide language support" checkbox, which makes the
"A" flavored APIs use UTF-8 instead of some non-UTF-8 local encoding. With
that checkbox ticked, hg would crash in cmd.exe complaining
"LookupError: unknown encoding: cp65001"
