Use of _vec_len() to set vector length breaks address sanitizer.
Users should use vec_set_len(), vec_inc_len(), vec_dec_len () instead.

Currently the last character of the error message string
is temporarily changed to a null byte '\0' before the string
is sent to syslog(3), resulting in confusingly incomplete log
entries.
This patch changes the syslog format to "%.*s" so that the
maximum number of characters to be printed could be controlled.

Systemd always sends SIGCONT after KillSignal, to ensure that even suspended
tasks can be terminated cleanly. However, the default action of SIGCONT
handler in VPP such as unix_signal_handler() is process termination with
coredump, what is not really desired. So, leave it alike SIGSTOP with its
default handler.

If VPP is started in interactive mode, instead of sending logs to syslog
server we print them directly to stderr.
Output is colorized, but that can be turned off with unix { nocolor }

Scenarios where SIGHUP is sent would include the user closing an xterm
while in interactive/nodaemon mode, or similarly when running vpp in the
same mode during testing (e.g., using ssh to run VPP on a DUT). VPP
should exit in these cases; however, generating a core is unwanted.

The "nosyslog" option disables syslog just like the "interactive" mode
but can be used together with "nodaemon".
This is useful for when VPP is running under a process supervisor like
runit or daemontools that pipe the stdout/stderr to a dedicated logger
service.

When profiling VPP with MAP (a software profile suite on Arm CPUs, see details in
https://www.arm.com/products/development-tools/server-and-hpc/forge/map) on Arm
servers, VPP will receive SIGPROF signal because MAP uses SIGPROF signal to drive
its sampler to do profiling on VPP. However, the default action of SIGPROF signal
handler in VPP such as unix_signal_handler() is process termination. To profile
VPP with MAP, the SIGPROF handler should be left as default, and MAP sampler will
overwrite it with its own implementation.

Allow a plugin to override (suppress loading of) other plugins. This
mechanism allows a developer to prevent specific plugins from being
loaded.
To do so, provide an "overrides" list in the plugin definition:
VLIB_PLUGIN_REGISTER () =
{
<snip>
.overrides = "avf_plugin.so,ioam_plugin.so,dpdk_plugin.so",
};
or some such. Simply list the plugins in question as shown above. The
.overrides structure member is limited to 256 octets. The named .elf
section mechanism used to discover the vlib_plugin_registration_t's
precludes the use of a variable-length array of strings.
Use the vlib log to eliminate plugin and built-in vat plugin loader
console spew.
Added vlib_log_register_class_rate_limit(...) to allow procedural
configuration of the log rate-limit. We *never* want to rate-limit
plugin loader messages.

The vlib init function subsystem now supports a mix of procedural and
formally-specified ordering constraints. We should eliminate procedural
knowledge wherever possible.
The following schemes are *roughly* equivalent:
static clib_error_t *init_runs_first (vlib_main_t *vm)
{
clib_error_t *error;
... do some stuff...
if ((error = vlib_call_init_function (init_runs_next)))
return error;
...
}
VLIB_INIT_FUNCTION (init_runs_first);
and
static clib_error_t *init_runs_first (vlib_main_t *vm)
{
... do some stuff...
}
VLIB_INIT_FUNCTION (init_runs_first) =
{
.runs_before = VLIB_INITS("init_runs_next"),
};
The first form will [most likely] call "init_runs_next" on the
spot. The second form means that "init_runs_first" runs before
"init_runs_next," possibly much earlier in the sequence.
Please DO NOT construct sets of init functions where A before B
actually means A *right before* B. It's not necessary - simply combine
A and B - and it leads to hugely annoying debugging exercises when
trying to switch from ad-hoc procedural ordering constraints to formal
ordering constraints.

crash stack backtrace will be directed to syslog
1. make use of glic backtrace in execinfo.h. the old clib_backtrace is removed
2. install SIGABRT in signal handler, but have to remove it when backtrace is
done. reason is to capture stack trace caused by SIGABRT. vPP ASSERT always
call os_exit then abort(). we definitely want to know the trace of this
situation. It is a little tricky to avoid SIGABRT infinite loop
3. always load symbols by calling clib_elf_main_init () in main(). Otherwise,
PC addresses instead of symbols will be displayed.

This patch deprecates stack-based thread identification,
Also removes requirement that thread stacks are adjacent.
Finally, possibly annoying for some folks, it renames
all occurences of cpu_index and cpu_number with thread
index. Using word "cpu" is misleading here as thread can
be migrated ti different CPU, and also it is not related
to linux cpu index.
