Prior to this commit, the VXLAN "create" API assumed
the vrf_id belonged to only the IPv4 FIB tables space.
With this commit, the FIB table is found in either the
IPv4 or IPv6 table as determined by the is_ipv6 flag.
This follows the same pattern that was already being
done in the CLI code for the VXLAN "create" command.

Rather than having multiple copies of the same function
scattered around, promote the function into the FIB
PROTOCOL definitions in fib_types.h.

Fixed a typo in tcp_push_header(). The typo only kicks in when the macro
VLIB_BUFFER_TRACE_TRAJECTORY is enabled.

This hash table intends to provide an alternative to the widely
used bihash table in places where either:
- Hash entry timeout is required
- The hash table data does not fit in CPU cache
Although the bihash table is very fast, each lookup requires
accessing two cache lines in a serialized fashion. It works fine
when the hash table is in cache, but hits a wall when it does not.
The 'flowhash' table uses a simplified design (at the cost of a
less good bucket auto-scaling) where each access only requires
a single memory lookup (in the absence of collision). The hash
table also uses a reduced number of registers.
In practice, a VPP node implementing a stateful feature would
typically:
- prefetch buffer metadata (in-cache)
- prefetch packet header (in-cache)
- compute hash & prefetch hash bucket (possibly in RAM)
- read/write key and value from bucket
Using this hash table, it is possible to pipeline accesses in a way
that does not exhaust CPU's line field buffers, even when the
requested value is located in RAM (i.e. not in cache).
Measurements showed it was possible to scale to tens of millions
of flows (with a full 5-tuple matching and 32B value, i.e. 1
cache line per flow) with no performance degradation when
the hash table grows to the point it doesn't fit in cache anymore.
I have used this table in a couple of non-open-sourced projects,
but think it might be useful to lb, nat, and possibly other VPP
subsystems.
More information in the .h file.

When building plugins outside of the VPP tree, the vppapigen
tool requires the use of the C.py / JSON.py code. To that end,
install it in /usr/share/vpp as referenced.

a crash on debug image (VPP-1151)
In debug image, there is extra code to validate the buffer when it is
freed. It uses the hash table to lookup the buffer index with spinlock
to prevent contention. However, there is one spinlock for each worker
thread. So allocating the buffer on thread-x and freeing the same buffer
on thread-y causes the validation to fail on thread-y. The fix is to
have only one spinlock, stored in vlib_global_main.

This patch addresses the missing field in various data-structures to
track valuable information to implement the congestion-control
algorithms and manage sub-connections states.
It adds the possibility to queue up to 2 SACKs chunks when the connection
is not gapping.
At the same time, it pushes some variable/field renaming for better
readibility.

Add an SELinux profile such that VPP can run under SELinux on RPM based
platforms. The SELinux Policy is currently only implemented for RPM
packages, specifically, Fedora, CentOS and RHEL. Doxygen User
Documentation has been included (selinux_doc.md). Once some discussion
on file locations has completed (see vpp-devlist), updates to the Debug
CLI documentation will also need to be updated.
Additional changes:
Patch Set 2:
- Rework selinux_doc.md such that each line is only 80 characters
instead of each sentence on a line. Made additonal minor chnages
to the text.
- Update vHost Debug CLI documentation to reflex new socket location.
Cleaned up some text from when I originally wrote it, to better
reflex proper use.
- Update exec Debug CLI documentation to be more inline with suggested
helptext, added text regarding recommended script file location.
- For Debian builds, create the /var/log/vpp/ directory. I don't use
Debian very much, so please pay extra attention to
build-data/platforms.mk and build-root/deb/debian/.gitignore.
- Per discussion on VPP call, changed the default log location to
/var/log/vpp/vpp.log.
- Changed the socket location for vHost in AutoConfig to
/var/run/vpp/.
Patch Set 3:
- Update selinux_doc.md based on comments.

New API calls and corresponding CLI commands allow the user
to manage the socket filenames for memif connections using:
vppctl# create memif id <u32> filename <socket-filename>
vppctl# delete memif id <u32>
and then referencing it later in a memif interface:
vppctl# create memif <u32> socket-id <id> mode <mode> <master|slave> ...
Corresponding VAT cli entries have also been added.
The default memif socket file at id 0 are still always present.
The existing memif create/delete CLI commands have been slightly
altered into the new syntax:
vppctl# create interface memif ...
vppctl# delete interface memif ...
