Summary:
Make ServerState also store the clock as a member variable. This moves more
server-wide state into the ServerState class, and allows us to eliminate
another argument to the EdenMount constructor.

Summary:
Move the EdenCPUThreadPool from EdenServer to ServerState.
This ensures that all EdenMount objects always have a thread pool. Previously
most unit tests were creating an EdenMount without a thread pool set, but the
FileInode code and TreeInode code could end up wanting to use the thread pool
even if no FuseChannel is running.

Summary:
This adds a FakeFuse class to simulate a FUSE connection to the kernel, but
that is actually communicating with our userspace test harness code. This also
adds a FakePrivHelper class which implements the PrivHelper interface but
returns FakeFuse connections rather than real FUSE connections to the kernel.
This will enable us to write unit tests that exercise more of the FUSE and
EdenMount logic, and will also enable us to test error conditions and ordering
behaviors that are difficult to reliably reproduce with a real FUSE mount.
This also includes some very basic tests using this new code. The code in
fuse/test/FuseChannelTest.cpp creates a FuseChannel using a FakeFuse object,
and the code in inodes/test/FuseTest.cpp creates a full EdenMount object using
FakePrivHelper and FakeFuse. The tests are pretty similar for now, and only
exercise the FUSE initialization code. I will expand these tests in subsequent
diffs.

Summary:
Move all of the privhelper functionality into a PrivHelper class. The
ServerState object now stores the PrivHelper object to use, rather than having
a global singleton.
This will make it easier to stub out the PrivHelper functionality during unit
tests.
