Summary:
The functionality we care about is provided by the `fbamend`
extension. Therefore, lets replace the `amend` extension with the `fbamend`
extension.

The logic we care about has been moved to core so we can delete the
`inhibit` extension.

Summary:
We recently ran into issues with locks in pid namespaces [1]. Let's fix that
by using flock.
flock is more reliable in Linux's pid namespace use-case than file-existence
test, because it works without a /proc filesystem and does not have deadlock
issue if an hg process is killed unexpectedly (ex. OOM or SIGKILL).
The transition should be transparent:
- If the new code saw a symlink lock file generated by the old code.
`open(..., O_NOFOLLOW)` will fail and it's considered lock taken by the old
process correctly.
- If the old code saw a new lock file. It will treat it as system without
symlink support and it's considered lock taken by the new process correctly.
A non-symlink stale lock (regardless of whether it contains pid information or not)
will be confidently removed automatically by the new code.
The change is complicated because it works when both new and old hg
run at the same time. If we have migrated most users to the new code path,
the code can be cleaned up significantly.

Summary:
Split the infinitepush backups code into a separate module.
The infinitepush extension is responsible for providing scratch pushes, as well
as the server-side implementation for storing scratch bundles.
The infinitepushbackup extension uses this feature to provide automatic backup
support. It is an alternative to the commitcloud extension, and the two will
be mutually exclusive.
