 eal: provide option to set vhost_user socket owner/permissions

The API doesn't hold a way to specify a owner/permission set for vhost_user
created sockets.

Projects consuming DPDK started to do 'their own workarounds' like openvswitch
https://patchwork.ozlabs.org/patch/559043/
https://patchwork.ozlabs.org/patch/559045/
But for this specific example they are blocked/stalled behind a bigger
rework (https://patchwork.ozlabs.org/patch/604898/).

We need something now for existing code linking against DPDK. That implies to
avoid changing API/ABI. So I created a DPDK EAL commandline option based ideas
in the former patches.

Fixes LP: #1546565

*Update*
 - with the split libs it now nees to be listed in
   lib/librte_eal/linuxapp/eal/rte_eal_version.map to work on link steps
 - please note that upstream gravitates towards not extending but creating a
   new the API in DPDK as long term solution (will take a while)
 - also as listed before most affected projects seem to create their own
   workaround.
 So over time we have to check when we can drop it at the price of a config
 transition - likely OVS 2.6 won't need it anymore.

*Update*
 - the handling and lifecycle of this changed in Openvswitch 2.7 so we can no
   more use internal_config.
 - Also the upstreaming was aborted as that now clearly goes towards client
   mode vhost sockets for this (and other issues).
 - But until that is fully working we have to carry the workaround.
 - Updated to work with Openvswitch 2.7 (and backward compatible to 2.6)

 vhost: reject invalid log base mmap offset
 If the log base mmap_offset is larger than mmap_size then it points
 outside the mmap region.  We must not write to memory outside the mmap
 region, so validate mmap_offset in vhost_user_set_log_base().

 vhost: check log mmap offset and size overflow
 vhost_user_set_log_base() is a message handler that is
 called to handle the VHOST_USER_SET_LOG_BASE message.
 Its payload contains a 64 bit size and offset. Both are
 added up and used as a size when calling mmap().
 
 There is no integer overflow check. If an integer overflow
 occurs a smaller memory map would be created than
 requested. Since the returned mapping is mapped as writable
 and used for logging, a memory corruption could occur.
 
 This issue has been assigned CVE-2020-10722
Upstream: yes
