Summary:
Remove some TODOs. This serves as fallback paths where batch prefetch didn't happen.
I'd expect most use-cases will trigger IdStatic set's batch prefetch logic (to be
added).
I haven't decided what to do exactly with "contains". Fetching remotely there seems
to require some kind of negative cache (ex. in mutation records there might be nodes
not in the graph). But it _might_ be okay to say the "contains" is a local-only
operation, too. I leave it as-is and we'll see how the Python world uses "contains"
later.

Summary:
Updates native checkout to store which files have already been written
in .hg/upgradeprogress. Then enables it to load that file and skip writing those
files if they're already on disk and their mtime and size match the previously
written values. In theory we could record and check file hashes as well, but
that'd likely slow things down quite a bit.
Future diffs will add:
- Recording and checking the hgid that was written before vs what is about to be
written. Just an hgid comparison, not a full hash computation.
- Some UX to inform the user when hg checkout can be continued, and possibly to
implement 'hg checkout --continue'.

Summary:
Still trying to enable Scuba logging in ovrsource TD to figure out what caused Buck regression when we started working with multiple watchman instances.
Did not try previous fix of pgrp (deploying stuff on Sandcastle is not trivial), although now I'm not sure that pgrp was the issue. Hard to say.
But now I'm launching CI differently and observe different symptoms.
`eden start` command finishes in 30 seconds (according to logs), but Sandcastle waits for something for 10 minutes and then somebody kills `scribe_cat` and Sandcastle continues. I don't really know what that means, but there's another issue I discovered:
`scribe_cat` inherits a copy of stderr fs created during daemon startup.
This diff fixes the issue.

Summary:
`RendezVousConnection::new` can block for some time doing work on the CPU,
specifically creating the stats objects. This causes problems for other
futures during repo construction.
Instead, move rendez-vous construction to a `spawn_blocking` closure, so that
it doesn't interfere with the other futures.
Since `SqlBonsaiHgMapping::from_sql_connections` is not async, and is part of
the SqlConstruct trait, we must convert this to the builder pattern so that we
can defer rendez-vous construction to later on.

Summary:
The extensions loading logic built up an _order list to track what order extensions should be loaded in. It also treated that list as the list of what has already been loaded, if we load extensions multiple times (like once at dispatch, then later for repo creation). Unfortunately some extensions, like tweakdefaults, modify the _order list, so when extensions uses len(_order) to decide which extensions are new, it sometimes gets the wrong results because tweakdefaults has inserted values at the beginning of _order which messes up the offset.
This causes some extension's uisetup and extsetup to be invoked twice. With dynamicconfig on Windows, I was seeing pushrebase load twice, which caused an error due to double registering bundle2 parts.
Extension loading is a mess, so this whole ordering concept really doesn't make sense, but for now let's fix it by not relying on the _order offset.

Summary:
In the case where EdenFS crashes, any client performing IO to EdenFS would be
stuck in the D state waiting for the server to be back up and running. Since on
restart EdenFS will chose different ports, this makes it hard/impossible to
actually recover and will keep some process unkillable, often time requiring
rebooting a host.
To avoid this, we can make the mount "soft" which aborts the IO after some time
has elapsed and the server isn't back up. This should enable us to kill these
processes and recover more gracefully.

Summary:
When running `sudo mkscratch path /home/markamendoza`, the folder `/data/users/markamendoza/scratch/homeZmarkamendoza` will be created, including all parents that did not already exist. All these new directories will be created with owner = root.
Anticipating this kind of call, `mkscratch` already goes in and manually modifies the owner of the leaf directory (e.g. `/data/users/markamendoza/scratch/homeZmarkamendoza`), **but will not do so for any of the parent folders it created**.
This is normally not a problem, as long as `/data/users/markamendoza/scratch/` already exists. If it doesn't then these directories are created with the wrong ownership, which causes problems if we (for example) call `mkscratch` again, without sudo.
This diff remedies this by calling the same `set_file_owner` function (that's already called on the leaf directory) on all parents that were created by `mkscratch`

Summary:
During an `hg update`, all the loaded inodes are unloaded and forgotten, except
the ones that had a positive refcount, these are forgotten when FUSE calls the
`forget` API. For NFS, this `forget` API doesn't exist but the protocol relies
on file handle to stay valid for some time. The duration for which a file
handle need to stay alive depends on several factor. The root one needs to
always be valid, the rest relies on the lookup cache that the client keeps.
This lookup cache is invalidated when the mtime for the parent directory
changes, but mtime changes are often not immediately detected, as attributes
are cached client side with the `acdirmin` and `acregmin` for directories and
files.
For now, this diff doesn't attempt to deal with files being out of date right
after an `hg update`, it merely accounts for the NFS client being able to pass
old file handles to EdenFS. The astude reader will have noticed that
InodeNumber are never reclaimed for now, for that, a time-based mechanism will
need to be added to forget InodeNumbers that have expired.
