This is functionality peeled out of quick-read into a separate
translator.
Fops which modify the file (where it is required to perform the
operation on the true fd) will trigger and wait for the backend
open to succeed and use that fd.
Fops like fstat() readv() etc. will use anonymous FD (configurable)
when original fd is unopened at the backend.

- initialize xdata in qr_lookup even if it was NULL from top. This
allows qr to do its job even if lookup originated from fuse-resolve.c
- extend test cases to include 1 second delay and retry
- fix bug while checking condition for cached unwind
qr_readv_cached() unwinds if op_ret > 0. Therefore qr_readv()
must wind to subvol only if !(op_ret > 0) (i.e, op_ret <= 0).
- qr_readv_cached() is using uninitialized @conf pointer. Thanks
to Raghavendra Bhat for catching this!

- peel out 'open behind' functionality into a separate translator
- issue where, if file size had grown by revalidate, data was not flushed
- removed unnecessary acquistion of table->lock (e.g in qr_lookup())
- keep inode ctx persistent, prune only data (effectively changing the
order of lock acquisition from INODE -> TABLE)
- validation with readdirplus
- use variable size iobufs to simply cached reads
