fncachestore: defer updating the fncache file to a single file open

Defers updating the fncache file with newly added entries to the end of
the transaction (on e.g. pull), doing a single open call on the fncache
file, instead of opening and closing it each time a new entry is added
to the store.

Implemented by adding a new abstract write() function on store.basicstore
and registering it as a release function on the store lock in
localrepo.lock (compare with dirstate.write).

store.fncachestore overrides write() from basicstore and calls a new
write function on the fncache object, which writes all entries to the
fncache file if it's dirty.

store.fncache.add() now just marks itself as dirty if a new name is added.
