Lars Ellenberg 08d0dabf48 drbd: application writes may set-in-sync in protocol != C
If "dirty" blocks are written to during resync,
that brings them in-sync.

By explicitly requesting write-acks during resync even in protocol != C,
we now can actually respect this.

Andreas Gruenbacher 5e4722645a drbd: _req_conflicts(): Get rid of the epoch_entries tree
Instead of keeping a separate tree for local and remote write requests
for finding requests and for conflict detection, use the same tree for
both purposes.  Introduce a flag to allow distinguishing the two
possible types of entries in this tree.
