Summary:
This module previously used to handle deciding how a particular module should
be imported if it had multiple versions (e.g., pure Python or native).
However, as of D18819680 it was changed to always import the native C version.
Lets go ahead and remove it entirely now. Using `policy.importmod` simply
makes it harder for type checkers to figure out the actual module that will be
used.
The only functionality that `policy.importmod()` still provided was verifying
that the module contained a "version" field that looked like what was
expected. In practice these version numbers are not bumped often, so this
doesn't really seem to provide much value in checking that we imported the
correct version that we expected to be shipped with this release.

Summary:
This moves the build rules for the extensions in mercurial/cext into a TARGETS
file in this directory.
This will allow us to start writing `*.pyi` files that contain type
information for these modules, and store them alongside the corresponding `.c`
files. By having the build rules in the top-level `eden/scm` directory we
would have needed to keep the `.pyi` files for these modules directly in the
`eden/scm` directory instead, as the namespace for the `pyi` files is assumed
to be the basemodule plus their path relative to the TARGETS file.

Summary:
This error handling can be extremely slow: calling `self.node()` can end up
triggering a linkrev scan of the changelog, which can take over 5 minutes.
If we did want to add this back in the future we would need some sort of API
on `filectx` to try and get the node ID only if it was cheap, and that would
fail fast if this is using remotefilelog and trying to get the node ID will
require scanning the changelog.
Note that KeyError can occur fairly regularly when invoked in long-lived
commands like `hg debugedenimporthelper`. If we are asked about data in a new
commit that was added since this repository was originally opened a KeyError
will be thrown here (in which case `debugedenimporthelper` will call
`repo.invalidate()` and then retry).

Summary:
With the LFS store being added, and the indexedlog being soon used for trees,
this simplification should help in formalizing the hierarchy of files/folders.
It will look like the following:
<root dir>/lfs: for the lfs store
<root dir>/indexedlog*: for the indexedlog
<root dir>/foobar: for a hypothetical foobar store
For manifests, <root dir> will therefore be: <store dir>/manifests. The
unfortunate part is that the current tree data lives under
<store dir>/packs/manifests. As packfiles will be replaced, this small
discrepency is acceptable.

This is the first step in having a stronger integration between LFS blobs and

As of now, no reclamation is being performed for shared blobs, blobs aren't

Summary:
The former implementation here was a little difficult to work with, and
resulted in a whole lot of cloning of closures, etc.
This updates the implementation to be a little simpler on the whole (async /
await is nicer for while loops, since you can use, well, loops)
It does slightly change a few parts of the behavior:
- The old implementation would wait for the replication lag duration. That's
not really correct. As we've observed several time this weeks, replication
lag usually drops quickly once it starts dropping. I.e. if the replication
lag is 10 seconds, it doesn't take 10 seconds to catch up. This gets more
important with big lag durations.
- I updated replication lag to be u64 instead of usize. usize doesn't really
make sense for something that has absolutely nothing to do with our pointer
size.
I also split out the logic for calculating how long we wait in a part that
cares about whether we are busy and one that cares about replication lag
(whereas the older one kinda mixed the two together). We wait for our own
throttling (i.e. sleep for a sec if we didn't do anything) before we wait for
replication lag, so the new behavior should have the desired behavior of:
- If we don't have much work to do, we sleep 1 second between each iteration
(but if we do have work, we don't).
- No matter what, if we have replication lag, we wait until that passes before
doing any work.
The old one did that too, but it mixed the two calculations together, and was
(at least in my opinion) kinda hard to reason about as a result.

Summary:
Our blobstore_sync_queue selects entries with a limit on the number of unique
keys it's going to load. Then, it tries to delete them. However, the number of
entries might be (much) bigger than the number of keys. When we try to delete
them, we time out waiting for MySQL because deleting 100K entries at once isn't
OK.
This results in crashlooping in the healer, where we start, delete 100K
entries, then time out.
This is actually double bad, because when we come back up we just go wihhout
checking replication lag first, so if we're crashlooping, we disregard the
damage we're doing in MySQL (I'm fixing this later in this stack).
So, let's be a bit more disciplined, and delete keys 10K at a time, at most.

Summary:
On Windows, there are *two* 8-bit encodings for each process.
* The ANSI code page is used for all `...A` system calls, and this is what
Mercurial uses internally. It can be overridden using the `--encoding`
command line option.
* The OEM code page is used when outputing to the console. Mercurial has no
concept of this, and instead renders to the console using the ANSI code page,
which results in mojibake like "Θ" instead of "é".
Add the concept of an `outputencoding`. If this differs from `encoding`, we
convert from the local encoding to the output encoding before writing to the
console.
On non-Windows platforms, this defaults to the same encoding as the local encoding,
so this is a no-op unless `--outputencoding` is manually specified.
On Windows, this defaults to the codepage given by `GetOEMCP`, causing output
to be converted to the OEM codepage before being printed.
For ordinary strings, the local encoded version is wrapped by `localstr` if the
encoding does not round-trip cleanly. This means the output encoding works
even if the character is not represented in the local encoding.
Unfortunately, the templater is not localstr-clean, which means strings can get
flattened down to the local encoding and the original code points are lost. In
this case we can only output characters which are in the intersection of the
encoding and the output encoding.
Most US English Windows systems use cp1252 for the ANSI code page and cp437 for
the OEM code page. These both contain many accented characters, so users with
accented characters in their names will now see them correctly rendered.
All of this only applies to Python 2.7. In Python 3, everything is Unicode,
the `--encoding` and `--outputencoding` options do nothing, and it just works.
