Pass the block_device and operation that we plan to use this bio for to bio_alloc_bioset to optimize the assigment. NULL/0 can be passed, both for the passthrough case on a raw request_queue and to temporarily avoid refactoring some nasty code.
Also move the gfp_mask argument after the nr_vecs argument for a much more logical calling convention matching what most of the kernel does.

block: replace bi_bdev with a gendisk pointer and partitions index
This way we don't need a block_device structure to submit I/O. The block_device has different life time rules from the gendisk and request_queue and is usually only available when the block device node is open. Other callers need to explicitly create one (e.g. the lightnvm passthrough code, or the new nvme multipathing code).
For the actual I/O path all that we need is the gendisk, which exists once per block device. But given that the block layer also does partition remapping we additionally need a partition index, which is used for said remapping in generic_make_request.
Note that all the block drivers generally want request_queue or sometimes the gendisk, so this removes a layer of indirection all over the stack.

block: replace REQ_NOIDLE with REQ_IDLE
Noidle should be the default for writes as seen by all the compounds definitions in fs.h using it. In fact only direct I/O really should be using NODILE, so turn the whole flag around to get the defaults right, which will make our life much easier especially onces the WRITE_* defines go away.
This assumes all the existing "raw" users of REQ_SYNC for writes want noidle behavior, which seems to be spot on from a quick audit.

drbd: al_write_transaction: skip re-scanning of bitmap page pointer array
For larger devices, the array of bitmap page pointers can grow very large (8000 pointers per TB of storage).
For each activity log transaction, we need to flush the associated bitmap pages to stable storage. Currently, we just "mark" the respective pages while setting up the transaction, then tell the bitmap code to write out all marked pages, but skip unchanged pages.
But one such transaction can affect only a small number of bitmap pages, there is no need to scan the full array of several (ten-)thousand page pointers to find the few marked ones.
Instead, remember the index numbers of the few affected pages, and later only re-check those to skip duplicates and unchanged ones.

drbd: introduce WRITE_SAME support
We will support WRITE_SAME, if * all peers support WRITE_SAME (both in kernel and DRBD version), * all peer devices support WRITE_SAME * logical_block_size is identical on all peers.
We may at some point introduce a fallback on the receiving side for devices/kernels that do not support WRITE_SAME, by open-coding a submit loop. But not yet.

drbd: finish resync on sync source only by notification from sync target
If the replication link breaks exactly during "resync finished" detection, finishing too early on the sync source could again lead to UUIDs rotated too fast, and potentially a spurious full resync on next handshake.
Always wait for explicit resync finished state change notification from the sync target.

drbd: avoid potential deadlock during handshake
During handshake communication, we also reconsider our device size, using drbd_determine_dev_size(). Just in case we need to change the offsets or layout of our on-disk metadata, we lock out application and other meta data IO, and wait for the activity log to be "idle" (no more referenced extents).
If this handshake happens just after a connection loss, with a fencing policy of "resource-and-stonith", we have frozen IO.
If, additionally, the activity log was "starving" (too many incoming random writes at that point in time), it won't become idle, ever, because of the frozen IO, and this would be a lockup of the receiver thread, and consquentially of DRBD.
Previous logic (re-)initialized with a special "empty" transaction block, which required the activity log to fully drain first.
Instead, write out some standard activity log transactions. Using lc_try_lock_for_transaction() instead of lc_try_lock() does not care about pending activity log references, avoiding the potential deadlock.

To be able to "force out" an activity log transaction, even if there are no pending updates.
This will be used to relocate the on-disk activity log, if the on-disk offsets have to be changed, without the need to empty the activity log first.
While at it, move the definition, so we can drop the forward declaration of a static helper.

block: add a bi_error field to struct bio
Currently we have two different ways to signal an I/O error on a BIO:
(1) by clearing the BIO_UPTODATE flag (2) by returning a Linux errno value to the bi_end_io callback
The first one has the drawback of only communicating a single possible error (-EIO), and the second one has the drawback of not beeing persistent when bios are queued up, and are not passed along from child to parent bio in the ever more popular chaining scenario. Having both mechanisms available has the additional drawback of utterly confusing driver authors and introducing bugs where various I/O submitters only deal with one of them, and the others have to add boilerplate code to deal with both kinds of error returns.
So add a new bi_error field to store an errno value directly in struct bio and remove the existing mechanisms to clean all this up.
