Summary:
On Windows, computing the sha1 of a materialized file requires opening up the
file in the working copy, as the file is cached there. Interestingly, this
potentially means that for computing the sha1 of a file, EdenFS may receive a
callback from ProjectedFS about that file or a parent directory. At this point,
EdenFS just refuses to serve this callback, as doing so may trigger an infinite
loop, or simply deadlocks. While this may sound weird, recursive callbacks are
not expected, as this signify that EdenFS view of the working copy doesn't
match what it actually is.
To close the loop, and from a code perspective, this means that computing the
sha1 of a file can fail and can throw an exception. Unfortunately, the code
didn't reflect this fact and exceptions were simply ignored, when that happens
during a checkout operation, this can leave the working copy in a weird state,
further agravating the mismatch between EdenFS view of the working copy, and
what it actually is.

Summary:
While on Linux these can't fail (or, to be more precise: it doesnt' matter),
they can on Windows. One such exemple is when a user lock a file and triggers
an update that modifies this file. The invalidation will fail, and thus the
update should keep track of that file not being updated properly.
Previously, the invalidation would raise an exception, but that proved to be
the wrong approach as some state would need to be rolled back which the
exception didn't help in. For that, let's just return a Try and make sure that
we handle all the cases properly.

Summary:
Cache invalidation is hard, and on Windows we avoided doing a lot of them. It
turns out, this was the wrong decision as it's fairly easy to find cases where
the filesystem view is different from the manifest state.
Since the Linux code is most likely correct in where the invalidation is done,
let's also do the same on Windows, removing a whole lot of #ifdef. It is very
likely that as a result of this diff we end up invalidating more than needed,
thus slowing down EdenFS, but at this point I'd prefer to err on the side of
correctness, performance will come later.
While invalidating files should use PrjDeleteFile, for directories, we simply
need to mark them as placeholder, as directories created by a user won't have a
placeholder, thus ProjectedFS would bypass EdenFS when listing in.

Summary:
An assertion error is raised if `eden doctor` is in the middle of a merge. This is because we enter a specific "if" condition in the case that mercurial has two parent commits, and EdenFS only ever tracks `p0`, so EdenFS simply sets `p1` to the null commit in `_select_new_parents()`. Specifically, this is in the case in which both `_old_dirstate_parents` and `_old_snapshot` are not None.
Because `_old_dirstate_parents` has `p1` set to nonnull, and Eden thinks it is null , the check `self._new_parents != self._old_dirstate_parents` would be `True` even though there was actually no error.

Summary:
In the past, if an EdenMount got stuck while shutting down (inodes still referenced), the EdenMount would already be removed from the server's `mounPoint's` map while stuck. This resulted in `eden list` showing that the mount was not mounted, and then if we tried to remount the mount, we'd get a confusing error message about the not being able to grab the overlay lock. This also made it so if we tried to attach with gdb, or if we core dumped and tried to look at the data, we wouldn't be able to examine the object.
Instead, we should only remove the mount from the `mounPoints_` map after it has completely been shutdown. This will allow us to get better signal on the state of the mount (it will be in the `SHUTTING_DOWN` state in `eden list` instead of `(not mounted)`) and it will allow us to better debug these situations (where a mount is stuck shutting down) since we can get more information about the mount that is in this state.

Summary:
Add a command line argument to `edenfsctl doctor` to cause it to only report
problems with the current EdenFS instance, and to skip checks for system-wide
problems or other running EdenFS processes.
This does refactor a fair amount of the top-level doctor logic to encapsulate
most of the state into an `EdenDoctor` class.
This also updates the integration tests to use this flag when invoking
`edenfsctl doctor`. Previously the integration tests could spuriously fail
due to other pre-existing problems on the system, or due to other EdenFS
instances that are currently being started or shut down by other tests running
in parallel.

Summary:
D17135557 added a bunch of `pyre-fixme` comments to the EdenFS integration
tests for cases where Pyre cannot detect that some attributes are initialized
by the test case `setUp()` method.
It looks like Pyre's handling of `setUp()` is somewhat incorrect: it looks
like if a class has a `setUp()` method this currently suppresses all
uninitialized attribute errors (even if some attributes really are never
initialized). However, Pyre does not detect `setUp()` methods inherited from
parent classes, and always warns about uninitialized attributes in this case
even they are initialized.
Lets change these comments from `pyre-fixme` to `pyre-ignore` since this
appears to be an issue with Pyre rather than with this code. T62487924 is
open to track adding support for annotating custom constructor methods, which
might help here. I've also posted in Pyre Q&A about incorrect handling of
`setUp()` in derived classes.

Summary:
Add a new thrift API for computing the difference between the working
directory and a given source control commit.
This has the following differences from the old getScmStatus() commit:
- The parameters are accepted in a GetScmStatusParams structure now.
This makes it easier for the server-side C++ implementation to tell which
parameters have actually been specified by the caller. This will make it
easier to extend this API in the future without having to replace it with a
new function call again.
- The return value is a GetScmStatusResult, which includes both the ScmStatus
and the EdenFS version number. This will allow code like `hg status` to get
both the status results and the EdenFS version in a single call, without
needing to make multiple separate thrift calls.
- This new call will return an error if the caller requests the status against
a commit that disagrees with EdenFS's view of the current commit. Because
the individual `hg` command line processes do not perform any
synchronization of their own when reading the working directory parent,
they can often call EdenFS with stale parent information, or while a
checkout is currently in progress. This new behavior will reject the
request with an error, rather than having EdenFS perform a potentially very
expensive status computation when the results probably aren't actually
useful to the caller anyway.
