Summary:
EdenFS on Windows is a bit weird as ProjectedFS is implemented as a filter
driver that adds reparse point to all the files/directories to get notified of
filesystem operations on them. It then hides these reparse points from the
outside which means that the dwAttributes of a file in EdenFS will not claim
that a reparse point is attached to it. On top of this, newly created
files/directories won't have any reparse points attached to them, until they
start being tracked by EdenFS.
While the first issue can be solved by always querying the reparse tags, I'm
not entirely sure how to solve the second one. That second issue causes
Mercurial to always try to create hardlink in the .hg directory, while it shouldn't.

Summary:
In a strongly typed langage, using strings should be avoided whenever possible
as they do not provide the safety guarantees that types provide.
I took the liberty of removing all the filesystems that are not relevant for
Mercurial for simplification reasons. If needs arise, we can always add a new
FsType to the enum.

Summary:
Without this:
In [3]: util.getfstype('')
IOError: [Errno 2] No such file or directory (os error 2)
And there is a code path hitting this:
File "edenscm/mercurial/util.py", line 1483, in checknlink
fstype = getfstype(os.path.dirname(testfile))
# testfile = '.'
# os.path.dirname(".") = ""
The old implementation works fine for an empty path:
In [2]: m.util.getfstype('')
Out[2]: 'eden'
So let's make the new Rust implementation consistent.

Summary:
Only keep type parameters at the top-level function.
This reduces the binary size and speeds up rustc.

Summary:
Rename the main method to "fstype". The API has no relation with repo.
So let's rename it.
