spdk_env_opts->env_context may now contain a DPDK-specific
string that will be appended directly into rte_eal_init().
It can be used to e.g. override the default EAL loglevel,
which was hardcoded to RTE_LOG_NOTICE so far.
This is primarily meant to be used during development.
As a test for this feature, the vtophys test app will now
set the highest possible EAL loglevel which will give us
a ton of additional debug logs.
Note: the opts->env_context field is implementation-specific
and hence the vtophys app needs to check if it's run with
our env_dpdk. As SPDK_CONFIG_ENV is a raw text not even
surrounded with quotation marks, the vtophys app needs to
do a bit of #define magic to make it a string.

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.

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

the future.
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.

There is no reason for this test to consume all of
the huge pages on the system. 256MB is sufficient.

Freebsd complains:
`error: redefinition of typedef 'rte_mem_event_callback_t' is
a C11 feature [-Werror,-Wtypedef-redefinition]`
Those typedefs are already defined in rte_memory.h, we can use
them directly.

Add a check to prevent spdk_mem_map_set_translation() or
spdk_mem_map_clear_translation() calls that start within the valid
address range but specify a size that would access parts of the mem map
outside of the valid region.
spdk_mem_map_translate() is safe without any extra checks since it only
accesses the first entry regardless of size, and the MASK_256TB check
catches out-of-range accesses to that entry.

The arrays for both the map_256tb and map_1gb structures were twice
as large as necessary; fix the sizes and add unit tests for the boundary
conditions to verify that the fix works.

This brings DPDK 18.05 support and introduces
dynamic hugepage memory allocation.
The following is now possible:
./spdk_tgt -s 32
rpc.py construct_malloc_bdev 128 512
or even:
./spdk_tgt -s 0
Note that if no -s param is given, DPDK will still
allocate all available hugepage memory.
This has been tested with DPDK 18.05-rc6.
