- On 'restart' close all registered files (except stdio) so that the
new process has a clean start; in particular, CLI sockets, API
sockets, tun/af_packet etc descriptors all need to close so they're
not left open but unused by the new VPP process. To do this we iterate
all the files registered for the polling mechanism and close() them.[1]
- While we're here, retain the original environment on 'restart';
several things make use of it.
[1] An alternative mechanism would be to mark all files with CLOEXEC
on opening; I think that is a little fragile for this fairly esoteric
use case.

- CLI history forward-search is bound to ^S which is common, but
that is also the tty's default control byte to pause output.
So we disable XON/XOFF in the tty so that we can use ^S.

- Terminals do not reverse-line-wrap when the cursor is at the left
edge and \b tries to make it go left.
- Instead, we have to track the cursor position if we need to emit \b's
and if we are at the left edge emit an ANSI sequence to relocate
the cursor. Previously we usually simply calculated the new cursor
position after a bunch of output had completed.
- Further trickiness is required since most xterm-like terminals also
defer moving the cursor to the next line when at the right edge[1], and
then if they receive a \b move the cursor back one character too many.
- This requires intricate reworking of everywhere that \b is emitted
by the CLI code during command line editing.
[1] Bash counters this issue by tracking the cursor position as output
is generated and forcing the cursor to the next line (by emitting
a space followed by \r) if it gets to this phantom cursor position);
here we effectively do that but only if the user tries to go left
when in this state.

- The last line in the pager buffer was sometimes missed when
using space/pg-dn; simple off-by-one error.

if you plan to put a hash into shared memory, the key sum and key
equal functions MUST be set to constants such as KEY_FUNC_STRING,
KEY_FUNC_MEM, etc. -lvppinfra is PIC, which means that the process
which set up the hash won't have the same idea where the key sum and
key compare functions live in other processes.

This is ~50% improvement in buffer alloc performance.
For a 256 buffer allocation, it was ~10 clocks/buffer, now is < 5 clocks.

When calling vlib_buffer_clone() on a source vlib_buffer with no next
buffer but whose total_length_not_including_first_buffer hadn't been
properly zeroed out, the total_length_not_including_first_buffer of
the clone was set to a wrong value.

Object sizes must evenly divide alignment requests, or vice
versa. Otherwise, only the first object will be aligned as
requested.
Three choices: add CLIB_CACHE_LINE_ALIGN_MARK(align_me) at
the end of structures, manually pad to an even divisor or multiple of
the alignment request, or use plain vectors/pools.
static assert for enforcement.

While some levels such as debug and emerg work, others don't. See below.
DBGvpp# set log class tap level warn
set log class tap level warn
set logging class: unknown input `level warn'
DBGvpp# set log class tap level debug
set log class tap level debug
DBGvpp# set log class tap level info
set log class tap level info
set logging class: unknown input `level info'
DBGvpp# set log class tap level err
set log class tap level err
DBGvpp# set log class tap level crit
set log class tap level crit
set logging class: unknown input `level crit'
DBGvpp# set log class tap level emerg
set log class tap level emerg
DBGvpp#
Cause:
The reason for the failure for the shorter keywords is level_str is unformatted
with %v which is not null terminated. For example, the character after "info"
could be anything in level_str. The memcmp with size of the macro keyword __##uc
which includes the null character or 5 in this case and thus the comparison fails.
Fix:
Use %s which insure level_str is null terminated. Use strcmp to rule out
false positve match like "debugxxx" against keyword "debug".

Change vlib_buffer_add_data() so it interprets ~0 to mean please
allocate a new buffer, instead of 0. Fixed a couple of calls to pass
~0 instead of 0.
Zero has always been a valid buffer index, we never happened to
actually use it until recent buffer allocator changes.
The presenting symptom: ASSERT failure when running "make
TEST=test_mpls test-debug"
