This patch refines discard support of the sheepdog driver. The
existing discard mechanism was implemented on SD_OP_DISCARD_OBJ, which
was introduced before fine grained reference counting on newer
sheepdog. It doesn't care about relations of snapshots and clones and
discards objects unconditionally.
With this patch, the driver just updates an inode object for updating
reference. Removing the object is done in sheep process side.
sheepdog: use per AIOCB dirty indexes for non overlapping requests
In the commit 96b14ff85acf, requests for overlapping areas are
serialized. However, it cannot handle a case of non overlapping
requests. In such a case, min_dirty_data_idx and max_dirty_data_idx
can be overwritten by the requests and invalid inode update can
happen e.g. a case like create(1, 2) and create(3, 4) are issued in
parallel.
This patch lets SheepdogAIOCB have dirty data indexes instead of
BDRVSheepdogState for avoiding the above situation.
This patch also does trivial renaming for better description:

muldiv64() is used to convert microseconds into CPU ticks.
But it is not clear and not commented. This patch uses macro
to clearly identify what is used: time, CPU frequency and ticks.
For an elapsed time and a given frequency, we compute how many ticks
we have.
