This patch teaches worer threads to sleep and to be waken up by
kernel if there is activity on file desctiptors assigned to that thread.
It also adds counters to epoll file descriptors and new
debug cli 'show unix file'.

This patch address the need to send/receive heartbeats between peers.
At the same time, the number of unacked heartbeats is tracked and when
the peer requests to send DATA to the remote-peer the value of unacked
heartbeats needs to be checked against the maximum value allowed for
retransmissions. If the unacked heartbeats value is higher then the
remote-peer is considered unreachable and the connetion needs to be
shutdown.

Normally session keys are generated by mirroring the packets sent.
ICMP message type should be used and inverted for the stateful ACL.
Supported ICMP messages with this patch:
- ICMPv4: Echo/Timestamp/Information/Address Mask requests
- ICMPv6: Echo request/Node Information Queury
The invmap & valid_new tables can be modified to make any other
ICMP messages to be reflexive ACL.

Clients cannot know at svm region detach time if the shm backing files
have been recreated (e.g., if vpp restarts) and therefore should not try
to unlink them. Otherwise, terminating clients attached to previous
instantiations of a re-allocated region end up making the new instance
un-mappable by removing its backing file.

L3DSR is used to overcome Layer 2 limitations
of Direct Server Return Load Balancing.
It maps VIP to DSCP bits, and reuse TOS bits to transfer it
to server, and then server will get VIP from DSCP-to-VIP mapping.

This patch addresses the need to handle out-of-order data chunks
received by a peer. To do that effectively, we had to add the handling
of data chunks flags (E/B/U bit) to understand whether the stream is
fragmenting user-message data and in that case if a fragment is the
FIRST/MIDDLE/LAST one of a transmission.
The same patch also addresses the security requirement to have a HMAC
calculated and incorporated in the INIT_ACK and COOKIE_ECHO chunks. The
algorithm used is the HMAC-SHA1.

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.

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.

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.
