Type: feature
Allow session cli filtering based on thread index, transport protocol,
session state and range of session pool indices. For instance
show session thread 1 proto tcp state ready range 0 20 verbose
Shows the session ids for the first 20 tcp sessions in thread 1 that are
in ready state.
To avoid excessive output that could reasult in the worker barrier being
held by the main thread for long periods of time, the session cli will
only output:
- session ids (verbose == 1) for a maximum of 50 sessions / worker
- verbose > 1 details for a maximum of 10 sessions

- use http sessions to track communication with peer (as opposed to
using the raw sessions)
- for static server send ok message prior to sending data
- static server can now handle GET requests spread over multiple
packets. Good for testing http/tcp implementation.

Have vcl poll and wait on the event message queues as opposed to
constantly polling the session fifos. This also adds event signaling to
cut through sessions.
On the downside, because we can't wait on multiple condvars, i.e., when
we have multiple message queues because of cut-through registrations, we
do timed waits.

- adds session layer support for datagram based protocols
- updates udp to work in pure connectionless and datagram mode. The
existing connected mode is now 'accessible' for apps as a dummy UDPC,
as in, connected udp, protocol.
- updates udp_echo, echo client, echo server code to work in datagram
mode.

used to manage session listeners in order to avoid overlap of

Applications are now provided the option to select the namespace they
are to be attached to and the scope of their attachement. Application
namespaces are meant to:
1) constrain the scope of communication through the network by
association with source interfaces and/or fib tables that provide the
source ips to be used and limit the scope of routing
2) provide a namespace local scope to session layer communication, as
opposed to the global scope provided by 1). That is, sessions can be
established without assistance from transport and network layers.
Albeit, zero/local-host ip addresses must still be provided in session
establishment messages due to existing application idiosyncrasies. This
mode of communication uses shared-memory fifos (cut-through sessions)
exclusively.
If applications request no namespace, they are assigned to the default
one, which at its turn uses the default fib. Applications can request
access to both local and global scopes for a namespace. If no scope is
specified, session layer defaults to the global one.
When a sw_if_index is provided for a namespace, zero-ip (INADDR_ANY)
binds are converted to binds to the requested interface.

177117: fstat() returns -1 on error; the code is
checking for any positive value instead
175142: final return could never be reached; simple
refactoring
175235,175236: Warning suppressed with an explicit
cast to (void)
174817: Final return couldn't be reached; is
is_in_order is 0 then 'rv' is already returned
above
172095,172093: If is_is_set does not get set to 1,
then return 0 has already been invoked
174405: Re-kill this (nothing sets rv)
171136: Looks like a cmd line flag to set test_bytes
was missing; added it, and refactored the
argc/argv processing to avoid two other
potential segv's
176813: Add range checking for term width/height.

for both.
175350: Fix implicit casting in shift operation

Simply call pool_init_fixed(...) before using the pool. Note that
fixed, preallocated pools live in individually-mmap'ed address
segments, except for the free element bitmap. A large fixed pool can
