Summary:
While EdenFS does not use a separate privhelper process on Windows, it still
defines a stub PrivHelper class. However, this class was previously defined
in a separate win/utils/Stub.h header file, which led to awkward `#ifdef`s to
include the correct platform-specific header file.
This diff moves the definition of the dummy PrivHelper class in Windows into
the same `PrivHelper.h` header file used on POSIX platforms. This results in
a few more `ifdef`s in the PrivHelper files, but fewer `ifdef`s in the calling
code, and will make it easier to start unifying more of the `EdenMain` logic
on Windows and non-Windows platforms.

This diff adds a fuse request timeout configuration setting
and threads it through to both the FuseChannel for our internal processing
and to the privhelper so that we can set an appropriate (slightly larger)

We're not that far from building privhelper on mode/mac but it does
require figuring out how to depend on osxfuse from the Buck build, so
bypass that by breaking the inodes target's dependency on privhelper's

Summary:
Add a call to tell the privhelper process to redirect its log messages to a
different file handle.
This call will make it possible for the privhelper processed to be forked
before the main edenfs process has processed the --logPath argument. The main
edenfs process can now drop privileges before it processes arguments and opens
the log file, and it can then pass the file handle to the privhelper process.

Summary:
Add a PrivHelper::detachEventBase() method, and rename PrivHelper::start() to
attachEventBase().
This makes it possible to detach a running PrivHelper from its EventBase and
re-attach it to an EventBase later to restart it. This will be useful in
upcoming diffs to allow performing calls to the PrivHelper before the main
thrift server EventBase has started.

Summary:
This updates the privhelper code to use the UnixSocket class for performing
I/O. This reduces the number of separate implementations of code we have for
sending file descriptors across Unix domain sockets, and also makes the
privhelper APIs non-blocking.
This will make it easier to clean up some of the initialization ordering in
the future. It will also make it easier to send file descriptors to the
privhelper server, instead of just receiving them. This may be helpful for
passing a file descriptor to use for logging to the privhelper process, which
will make it easier to fork the privhelper before logging redirection has
occurred.

Summary:
Up until now all of the privhelper APIs have been blocking calls. This
changes the privhelper functions to return Futures, and updates all users of
these APIs to be able to handle the results using Futures.
One benefit of this change is that all existing mount points are remounted in
parallel now during startup, rather than being mounted serially. The old code
performed a blocking `get()` call on the future returned by
`EdenServer::mount()`.
The privhelper calls themselves are still blocking for now--they block until
complete and always return completed Future objects. I will update the
privhelper code in a subsequent diff to actually make it asynchronous.

This is the key portion that makes the graceful restart

it informs the priv helper about the takeover mount and transfers
