Back when I put this together in 2015, ISO C11 was still reasonably new
and we couldn't require it just yet. Without ISO C11, there is no
"good" way (only bad hacks) to require a semicolon after a macro that
ends with a function definition. And if you added one anyway, you'd get
"spurious semicolon" warnings on some compilers...
With C11, `_Static_assert()` at the end of a macro will make it so that
the semicolon is properly required, consumed, and not warned about.
Consistently requiring semicolons after "file-level" macros matches
Linux kernel coding style and helps some editors against mis-syntax'ing
these macros.

Replace all lib/thread cancel macros, use thread_cancel()
everywhere. Only the THREAD_OFF macro and thread_cancel() api are
supported. Also adjust thread_cancel_async() to NULL caller's pointer (if
present).

We have this pattern in the code base:
if (thread)
THREAD_OFF(thread);
If we look at THREAD_OFF we check to see if thread
is non-null too. So we have a double check.
This is unnecessary. Convert to just using THREAD_OFF

We are using a enum to drive a switch statement and we have
a default case statement that can never be entered because
we know all the enum states have been covered. Remove it
from the code as that it cannot happen.

* zebra/kernel_socket.c: include "rt.h" to provide the prototypes of
kernel_init() and kernel_terminate();
* lib/prefix.h: remove the deprecation warning whenever ETHER_ADDR_LEN
is used. isisd uses the ETHER_HDR_LEN constant which is defined in
terms of ETHER_ADDR_LEN in the *BSD system headers. So, when building
FRR on *BSD, we were getting several warnings because we were using
ETHER_ADDR_LEN indirectly;
* lib/command_lex.l, lib/defun_lex.l: ignore other harmless warnings;
* lib/spf_backoff.c: cast 'tv->tv_usec' to 'long int' before printing.

Specifically, gcc 4.2.1 on OpenBSD 6.0 warns about these; they're bogus
(gcc 4.2, being rather old, isn't quite as "intelligent" as newer
versions; the newer ones apply more logic and less warnings.)

The FSF's address changed, and we had a mixture of comment styles for
the GPL file header. (The style with * at the beginning won out with
580 to 141 in existing files.)
Note: I've intentionally left intact other "variations" of the copyright
header, e.g. whether it says "Zebra", "Quagga", "FRR", or nothing.

The way thread.c is written, a caller who wishes to be able to cancel a
thread or avoid scheduling it twice must keep a reference to the thread.
Typically this is done with a long lived pointer whose value is checked
for null in order to know if the thread is currently scheduled. The
check-and-schedule idiom is so common that several wrapper macros in
thread.h existed solely to provide it.
This patch removes those macros and adds a new parameter to all
thread_add_* functions which is a pointer to the struct thread * to
store the result of a scheduling call. If the value passed is non-null,
the thread will only be scheduled if the value is null. This helps with
consistency.
A Coccinelle spatch has been used to transform code of the form:
if (t == NULL)
t = thread_add_* (...)
to the form
thread_add_* (..., &t)
The THREAD_ON macros have also been transformed to the underlying
thread.c calls.
