[PATCH v4 0/5] Support add/remove memory region & get-max-slots

[Pravin M Bathija <pravin.bathija@dell.com>]

This patchset incorporates support for adding and removal of memory
regions, getting max memory slots and other changes to vhost-user
messages.  These messages are sent from vhost-user front-end (qemu
or libblkio) to a vhost-user back-end (dpdk, spdk). Support functions
for these message functions have been implemented in the interest of
writing optimized code. Older functions, part of vhost-user back-end
have also been optimized using these newly defined support functions.
This implementation has been extensively tested by doing Read/Write
I/O from multiple instances of fio + libblkio (front-end) talking to
spdk/dpdk (back-end) based drives.  Also tested with qemu front-end
talking to dpdk + testpmd (back-end) performing add/removal of memory
regions. The last patch also includes increasing the number of memory
regions from 8 to 128. This has been also extensively tested using the
above test approaches.

  vhost: add user to mailmap and define to vhost hdr
  vhost_user: header defines for add/rem mem region
  vhost_user: support function defines for back-end
  vhost_user: Function defs for add/rem mem regions
  vhost_user: Increase number of memory regions
