[v4,0/8] Make shared memory config non-public

  This patchset removes the shared memory config from public
API, and replaces all usages of said config with new API
calls.

A lot of the patchset is a search-and-replace job and should
be pretty easy to review. The rest are pretty trivial EAL
changes.

v4:
- Rebase on top of latest master
- Squashed more commits
- Added some cleanups
  - Comment cleanup in mem config
  - Moved memseg list struct to rte_memory
- Fixed init in FreeBSD when storing data in config

v3:
- Rebase on top of latest master

v2:
- Collapsed all changes into fewer patches
- Addressed review comments
- Created a new file to store the code
- Changed namespace to "rte_mcfg_"
- Added some unification around config init
- Removed "packed" attribute from mem config
- Removed unnecessary inlining
- Added a check to explicitly forbid running multiprocess
  applications that differ in their DPDK versions

Anatoly Burakov (8):
  eal: add API to lock/unlock memory hotplug
  eal: add EAL tailq list lock/unlock API
  eal: add new API to lock/unlock mempool list
  eal: hide shared memory config
  eal: remove packed attribute from mcfg structure
  eal: uninline wait for mcfg complete function
  eal: unify and move mcfg complete function
  eal: unify internal config initialization
