Type:refactor
Moves connect, disconnect, bind, unbind and app detach to message
queue from binary api. Simplifies app/vcl interaction with the session
layer since all session control messages are now handled over the mq.
Add/del segment messages require internal C api changes which affect all
builtin applications. They'll be moved in a different patch and might
not be back portable to 19.08.

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

Enforce that variable length fields are the last element of API messages.
Add a 'fixed' version of string type, since dealing with
multiple variable length strings turned out too painful
for the C language bindings.
The string type is now:
{
string name[64]; // NUL terminated C-string. Essentially decays to u8 name[64]
string name[]; // Variable length string with embedded len field (vl_api_string_t)
};
The latter notation could be made available to other types as well.
e.g.
{
vl_api_address_t addresses[];
}
instead of
{
u32 n_addr;
vl_api_address_t addresses[n_addr];
};

Type:fix
Transports like tcp may notify session layer of a close but they may
defer the connection's deletion (e.g., tcp time-wait). During that time,
transports may still want to send packets. So, unless the session has no
transport (transport-deleted state), allow the transport to send.

Without this the use of uc0 is racy between the current thread and the
thread that owns it and will delete it.
This also ensures we don't trigger a read event on the session before
moving it to the right thread and notifying the application.

Previous implementation of clib_rwlock_t used two spinlocks: one
writer lock, and one to guard the counter for the number of readers.
This implementation uses a single condition variable rw_cnt which
has the following properties:
if a writer has the rwlock, rw_cnt = -1
if the rwlock is free, rw_cnt = 0
otherwise, rw_cnt > 0 and rw_cnt = number of readers
rw_cnt will never be less than -1
Benchmarking:
The results below are the cycle counts from test_rwlock.c, configured so
that for 10000 iterations, 6 reader and 6 writer threads on separate cores
are spawned such that each writer thread increments a global counter
10000 times in each iteration. For Taishan, 4 reader and 4 writer
threads are spawned in each test.

Multiple API message handlers call vnet_get_sup_hw_interface(...)
without checking the inbound sw_if_index. This can cause a
pool_elt_at_index ASSERT in a debug image, and major disorder in a
production image.
Given that a number of places are coded as follows, add an
"api_visible_or_null" variant of vnet_get_sup_hw_interface, which
returns NULL given an invalid sw_if_index, or a hidden sw interface:
- hw = vnet_get_sup_hw_interface (vnm, sw_if_index);
+ hw = vnet_get_sup_hw_interface_api_visible_or_null (vnm, sw_if_index);
if (hw == NULL || memif_device_class.index != hw->dev_class_index)
return clib_error_return (0, "not a memif interface");
Rename two existing xxx_safe functions -> xxx_or_null to make it
obvious what they return.

In contrast to the closing notification, whereby a transport informs
the session layer that is beginning the closing procedure, this allows
transports to notify the session layer of the fact that the transport is
"fully" closed, i.e., it expects no more data.
Also:
- adds app closed state for sessions
- changes tcp to have it notify when an active close has finished
