577b667ac3 test/env: add UNIT_TEST_NO_PCI_ADDR
Similar to UNIT_TEST_NO_VTOPHYS, we need this since
a future patch will result in some of the pci_addr
functions getting linked in via a new dependency
between memory.c and init.c.

f74d069ec0 env_dpdk: move vtophys.c contents to memory.c
CPU profiling on workloads with intensive vtophys
operations (i.e. very small CB-DMA transfers) exposed
overhead introduce by spdk_vtophys having to call
spdk_mem_map_translate in a different compilation
unit.  Let's just move the vtophys.c contents into
memory.c so that spdk_vtophys can inline
spdk_mem_map_translate and avoid this extra overhead.

This of course breaks the memory and vtophys unit
tests, so some additional changes are needed there
to keep everything linking correctly.

37b7a30894 memory: fix contiguous memory calculation for unaligned buffers
We assumed spdk_mem_map_translate() translates only 2MB-aligned
addresses, but that's not true. Both vtophys and NVMf can use it
with any user-provided address and that breaks our contiguous memory
length calculations. Right now each buffer appeared to have the
first n * 2MB of memory always contiguous.

This is a bugfix for NVMf which does check the mapping length
internally. It will also become handy when adding the similar
functionality to spdk_vtophys().

f4cb6c90b4 memory: register each hotplugged page separately
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.

a33e0943b0 memory: forbid registering a memory region more than once
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.

6bcd929500 memory: do not merge adjacent registrations
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.

6c30e783c1 ut/memory: refactor mem_map_alloc() tests to CUnit tests
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.

5d57386885 env_dpdk: spdk_mem_map_translate informs user of translation size.
This function will now check for whether or not a memory region is
contiguous accross 2MB map entries and return the total length of that

Also includes unittests
This series of changes is aimed at enabling spdk_mem_map_translate to
report back to the user the length of the valid mem_map up to the
function that requested the translation.
This will be useful when retrieving memory regions associated with I/O
buffers in NVMe-oF. For large I/O it will be possible that the buffer is
split over multiple MRs and the I/O will have to be split into multiple
SGLs.

spdk_mem_map_translate() is safe without any extra checks since it only
