Using AC_ARG_VAR function, it's possible to add LD, AR, OBJCOPY,
OBJDUMP, RANLIB and STRIP to the list of precious variables in
$ac_precious_vars for configure tool.
Doing this, we are enabling a new set of variables (HOST_LD, HOST_AR,
HOST_OBJCOPY, HOST_OBJDUMP, HOST_RANLIB and HOST_STRIP) useful for
cross-compiling when the target toolchain is prepending a prefix
to these tools.

Previous commits added LTTng tracepoints. This was primarily for testing
/ trial purposes; in practice we'd like to support arbitrary tracing
methods, and especially USDT probes, which SystemTap and dtrace expect,
and which are supported on at least one flavor of BSD (FreeBSD).
To that end this patch adds an frr-specific tracing macro, frrtrace(),
which proxies into either DTRACE_PROBEn() or tracepoint() macros
depending on whether --enable-usdt or --enable-lttng is passed at
compile time.
At some point this could be tweaked to allow compiling in both types of
probes. Ideally there should be some logic there to use LTTng's optional
support for generating USDT probes when both are requested.
No additional libraries are required to use USDT, since these probes are
a kernel feature and only need the <sys/sdt.h> header.
- add --enable-usdt to toggle use of LTTng tracepoints or USDT probes
- add new trace.h library header for use with tracepoint definition
headers
- add frrtrace() wrapper macro; this should be used to define
tracepoints instead of using tracepoint() or DTRACE_PROBEn()
Compilation with USDT does nothing as of this commit; the existing LTTng
tracepoints need to be converted to use the frrtrace*() macros in a
subsequent commit.

This commit adds initial support for LTTng.
When --enable-lttng=no or is not specified, no tracing code is included.
When --enable-lttng=yes, LTTng tracing events are (will be) generated.
configure.ac:
- add --enable-lttng
- define HAVE_LTTNG when enabled
- minimum LTTng version: 2.12.0

- add trace.[ch]

It's time to say good bye to libyang 0.16.105. The recently
released libyang 1.0.184 includes numerous bug fixes and performance
improvements that we need.
Despite the major version bump from 0.x to 1.x, the libyang API is
the same except for a single backward-incompatible change in the
user types interface (which we're currently not using). Hence no
code changes were necessary to adapt FRR to libyang 1.x.
This commit also reintroduces some leafrefs that needed to be
removed from our YANG modules due to a bug that was present on
libyang 0.16.105.

This is a full rewrite of the "back end" logging code. It now uses a
lock-free list to iterate over logging targets, and the targets
themselves are as lock-free as possible. (syslog() may have a hidden
internal mutex in the C library; the file/fd targets use a single
write() call which should ensure atomicity kernel-side.)
Note that some functionality is lost in this patch:
- Solaris printstack() backtraces are ditched (unlikely to come back)
- the `log-filter` machinery is gone (re-added in followup commit)
- `terminal monitor` is temporarily stubbed out. The old code had a
race condition with VTYs going away. It'll likely come back rewritten
and with vtysh support.
- The `zebra_ext_log` hook is gone. Instead, it's now much easier to
add a "proper" logging target.

We have also sent emails and asked around and have not found
anyone standing up saying that they are using Solaris.
Given the fact that we do not have any comprehensive testing
being done w/ solaris and the fact that we are getting a steady
stream of new features that will never work on solaris and
we cannot find anyone to say that they are using it. Let's

If in the mean-time someone comes forward with the fact that
they are using it we can then not deprecate it.

libyang 1.0 introduced a few changes in the user types API, and
these changes made FRR incompatible with libyang 1.x. In order to
ease our migration from libyang 0.x to libyang 1.x, let's disable
our libyang custom user types temporarily so that FRR can work
with both libyang 0.x and libyang 1.x. This should be especially
helpful to the CI systems during the transition. Once the migration
to libyang 1.x is complete, this commit will be reverted.
Disabling our libyang custom user types should have only
