We have hairy configuration method. First configure script uses CONFIG,
environment and arguments to produce CONFIG.local and config.h then
makefile uses CONFIG, environment and CONFIG.local to produce config.h
again. First time config.h can't be generated reliably as config.h
target in Makefile is passing MAKEFLAGS and they are unknown at
configuration phase.
Lets remove this mess by producing final mk/config.mk file and get rid
of CONFIG.local. This will also generate full build configuration in one
file instead scattering them in CONFIG and CONFIG.local.
In next patch scripts/genconfig.py can be removed.

Previously, the difference between configuring and offline is
unclear, this patch just fixes it. The key difference should be
whether the raid bdev have ever registered. Offline is registered
before but unregistered now, and configuring has never registered.
According to the above, we should never set configuring raid bdev to
offline because it never got registered.

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.

All mem_maps will still receive separate unregister
notification for each registered region, but the
public memory unregister API is more flexible now.
This follows the VFIO_TYPE1v2_IOMMU interface, which
allows the same.

Added sanity checks to prevent unregistering a memory

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.

Moved them from test/env/vtophys to test/env/memory
because that's where they should land in the first
place. Our memory ut already test allocating a mem_map,
so just extend them with an extra test case now. Since we're
a unit test rather than a fully-fledged SPDK app, we can
simplify the code a lot now - we no longer have any memory
(hugepages) registered at the beginning of our test case,
hence we no longer need to alloc multiple dummy mem maps to
iterate through all registrations - we can simply hardcode
and predict which registrations are there.

Newly registered mem maps weren't notified at vaddr 0
as we used value "0" to denote an unitialized, unset
variable. Since we *do* register vaddr 0 in our memory
unit tests let's switch unitialized vaddr value to
something different - like UINT64_MAX.
