The problem with registering the entire hotplugged memory
region is that it won't necessarily be unregistered in one
go. Registering each hugepage separately solves that
problem.
This puts a limitation on the number of pages that can
be allocated when using RDMA. We'll hopefully lift this
limitation sometime in future - probably levereging
ibv_rereg_mr, but for now we'll have to resort to either:
a) using 1GB hugepages
b) preallocating memory (with [-s|--mem-size <size>] app
param) as it will be registered as just one region no
matter what size it is. This memory won't be returned
to the system until the SPDK app exits.

Removed the reference count from the registrations map.
Although technically supported, registering a single memory
region more than once had a lot of unhandled cases and could
easily lead to a segfault.
RDMA maps require all memory to be unregistered in the same
chunks the memory was registered, which is often impossible
to achieve if a region was registered more than once:
1. register region 0x0 - 0x3 -> it gets mapped to
a single ibv_mr
2. register region 0x1 - 0x2 -> nothing happens, this region
is already registered
3. unregister region 0x0 - 0x3 -> 0x0-0x1 gets unregistered as
one region. 0x2-0x3 gets
unregistered as another
(leading to segfault in the
the current RDMA implementation)
The problem is that the last two regions share the same ibv_mr,
which SPDK tries to free twice. The second free causes a segfault.
vtophys map handles this case by registering each 2MB chunk
separately, but this solution cannot be applied for RDMA, as
NICs put a limitation (~2048) on the number of regions registered.
Another option is to keep a refcount of each ibv_mr allocated,
and free it only when the entire region was unregistered from the
SPDK mem map. This is however very tricky and RDMAmojo mentions
that freeing a memory buffer before unregistering its ibv_mr
may lead to a segfault.

Prevents us from unregistering two or more separately
registered regions with a single notification.
This fixes an ibv_mr leak in RDMA. When multiple registrations
were unregistered with a single notification, only the first
ibv_mr one would be freed and the remaining memory would
possibly still remain DMA-able.
As of now, unregistering multiple complete regions with
a single unregister call is not possible. It will be
implemented later, after the rest of the code is cleaned up.

Large read I/O will be typical in some use cases such as
web stream services. On the other hand, large write I/O
may not be typical but will be sufficiently probable.
Currently when large I/O is submitted to the RAID bdev,
the I/O will be divided by the strip size of it and then
divided I/Os are submitted sequentially.
This patch tries to improve the performance of the RAID bdev
in large I/Os. Besides, when the RAID bdev supports higher
levels of RAID (such as RAID5), it should issue multiple
I/Os to multiple base bdevs by batch fasion in the parity
update. Having experience in batched I/O will be helpful
in the future case too.
In this patch, submit split I/Os by batch until all child IOVs
are consumed or all data are submitted. If all child IOVs are
consumed before all data are submitted, wait until all batched
split I/Os complete and then submit again.
In this patch, test code is added too.

In the crypto examine function we first try to claim the bdev

to look at the entire global list of vbdevs.
The scenario that caught this was testing a duplicate underlying
bdev name in the conf file. In that case, before this fix, the claim
on the first crypto bdev worked but on the second it failed so the bdev
layer never added the good one to its global list so on exit it would
try to remove the crypto vbdev from the list but it was never added

Don't think this matters functionally but can be confusing in
debug, was using the name of the underlying bdev for the name of
the io_device we're registering. Change to the name of the vbdev
instead.

Currently write to bdev fails in _spdk_bdev_write_zero_buffer_next
due to other than -ENOMEM, assert is called.
RAID bdev using this feature is generally availale now and it will be
OK to remove this assert and return error instead.
Additionally, applying the factored function to _bdev_write_zero_buffer_next
will improve readability slightly.
These two changes are done in this patch.
