netfs: Miscellaneous preparatory changes

This a collection of miscellaneous modifications to netfslib that I want to
make ahead of bigger changes, including:

 (1) Convert "unsigned long long" to "uoff_t".  This makes it a little more
     obvious as to the meaning of the value.  Also convert some "loff_t" to
     "uoff_t" as most of the time it's used the value really should never
     be negative.

 (2) Remove the writethrough code as the locking is really tricky to get
     right and it looks like it could deadlock with Ceph if snapshots are
     used.

 (3) Adjust some tracepoints, including adding the cache object ID to
     certain tracepoinits.

 (4) Make use of PG_private_2 opt-in.  Use of PG_private_2 is deprecated
     and the MM people would like their page bit back, so we need to stop
     using it soon.

 (5) Add some helper functions to handle the barriering needed for the
     NETFS_RREQ_ALL_QUEUED flag.

 (6) Set the subrequest type at allocation time so that the allocation
     trace records the proposed type.
