the previous revision of blackmatch used a file_class to delegate all fuse
api operations on files to a specific per-file class, which is an option
given by the python-fuse bindings.
this is a pre-cursor to the 'split' client/server version, which uses a
simple, moreover flat, rpc mechanism to broker access to methods.

* fuse/impl_c: add --auto-fsid option
this was inspired by reading the fuse docs and discovering the 'fsid' option
to fuse_main, and was _intended_ to support a sort of 'stability' to the
filesystem (specifically derived from the root-uri mounted, whether directly
or via an alias) to support mac aliases across unmount/remount etc.
some experimentation shows that that doesn't actually work, and that, at
least for mac aliases in my testing, they're tied to path-to-mountpoint and
not to the fsid - which seems to have no bearing. perhaps the 'local' flag
is causing weirdness therein.
at any rate, I'm recording it simply for posterity, in case it turns out to
be useful after all somewhere down the road.

For a variety of reasons, high amongst them the fact that many people
interested in fuse support for tahoe seem to have missed its existence,
the existing fuse implementation for tahoe, previously 'mac/tahoefuse.py'
has been renamed and moved.
It was suggested that, even though the mac build depends upon it, that
the mac/tahoefuse implementation be moved into contrib/fuse along with
the other fuse implementations. The fact that it's not as extensively
covered by unit tests as mainline tahoe was given as corroboration.
In a bid to try and stem the confusion inherent in having tahoe_fuse,
tfuse and tahoefuse jumbled together (not necessarily helped by
referring to them as impl_a, b and c respectively) I'm hereby renaming
tahoefuse as 'blackmatch' (black match is, per wikipedia "a type of
crude fuse" hey, I'm a punny guy) Maybe one day it'll be promoted to
be 'quickmatch' instead...
Anyway, this patch moves mac/tahoefuse.py out to contrib/fuse/impl_c/
as blackmatch.py, and makes appropriate changes to the mac build process
to transclude blackmatch therein. this leaves the extant fuse.py and
fuseparts business in mac/ as-is and doesn't attempt to address such
issues in contrib/fuse/impl_c.
it is left as an exercise to the reader (or the reader of a message
to follow) as to how to deal with the 'fuse' python module on the mac.
as of this time, blackmatch should work on both mac and linux, and
passes the four extant tests in runtests. (fwiw neither impl_a nor
impl_b have I managed to get working on the mac yet)
since blackmatch supports a read-write and caching fuse interface to
tahoe, some write tests obviously need to be added to runtests.
