This is done by changing get_syscall() to either lookup the known syscall
or add it into the list with the default handlers for printing.
This also simplifies some code to not have to check if the syscall variable
is set or NULL.

when running the build-tools stage.
The requirement is due to the -P flag used when running m4 from usr.bin/lex
Makefile to generate skel.c. With the old m4 that fails and the failure is
ignored, resulting in an empty(-ish) skel.c, which leads to later build
failures when the misconfigured new lex tool is run.
This enables building -current (and 10-stable after MFC) on a stable-8
system again.

- Don't advertize trusted-computing capability in the Identify page.
This prevents Windows from issuing a TRUSTED_RECEIVE_DMA command.
- Windows will send down SMART and SECURITY_FREEZE_LOCK
even though smart and security capabilities were not advertized.
Send back a silent abort.

'rdrand' instruction may occasionally not return random numbers, in
spite of looping attempts to do so. The reusult is a KASSERT/panic.
Reluctantly accept this state-of-affairs, but make a noise about it.
if this 'noise' spams the console, it may be time to discontinue
using that source.
This is written in a general way to account for /any/ source that
might not supply random numbers when required.

- Socket file creation is limited to the ls -F testcase, greatly speeding up
the test process
- The ls -C testcase was made more robust by limiting the number of columns
via COLUMNS and by dynamically formulating the columns/lines.
- Add `atf_test_case` before all testcase `head` functions.

The general stack protector is known to be weak and has pretty small
coverage. While setting stack-protector-all would give better protection
it would come with a performance cost: for this reason Google's Chrome OS
team developed a new stack-protector-strong variant.
In addition to the protections offered by -fstack-protector, the new option
will guard any function that declares any type or length of local array,
even those in structs or unions. It will also protect functions that use a
local variable's address in a function argument or on the right-hand side
of an assignment.
The option was introduced in GCC-4.9, but support for it has been
back-ported to our base GCC (r286074) and is also available in clang.
The change was tested with dbench and doesn't introduce performance
regressions. An exp-run over the ports tree revealed no failures when
using the stricter stack-protector-all. Thanks to all testers involved.

For case (7) (new entry) nothing has to be done except lle_event.
Invoke this event directly from "create new lle" code block.
For case (4) (existing entry, same mac) useless mac update was performed,
along with LLENTRY_RESOLVED lle_event. There was no sense in doing that,
since nothing really had changed. Simply avoid this condition instead.
Given that, condition was simplified to (3),(5) states which can be merged
with previous block.
