Ben Walker d635d6d297 env: Add spdk_mem_reserve
The spdk_mem_reserve() function reserves a memory region in SPDK's
memory maps. This pre-allocates all of the required data structures
to hold memory address translations for that region without actually
populating the region.

After a region is reserved, calls to spdk_mem_register() for
addresses in that range will not require any internal memory
allocations. This is useful when overlaying a custom memory allocator
on top of SPDK's hugepage memory, such as tcmalloc.

This backport requires increasing SO_MINOR version, since it adds
new API. Version 2.1 does not conflict with any other, since on master
the API was increased from 2 to 3 SO_VER see:
(229ef16b) lib/env_dpdk: add map file and rev so major version.
