This is most of the old code bolted on top of the new "backend"
infrastructure. It just wraps around zlog_fd() with the string search.

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.

This fixes a warning on daemons that use route map about filter yang
model not being included in the binary.

Based on the route map old CLI, implement the route map handling using
the exported functions.
Use a curry-like programming pattern avoid code repetition when
destroying match/set entries. This is needed by other daemons that
implement custom route map functions and need to pass to lib their
specific destroy functions.

This - mostly intended for BMP - implements a pull-driven write buffer
filled on demand by a callback with some reasonable buffering logic.
I don't expect it to be that useful in other places, but it's not BMP
specific so it's properly split off in its own place.

Add a file that exposes functions which modify nexthop groups.
Nexthop groups are techincally immutable but there are a
few special cases where we need direct access to add/remove
nexthops after the group has been made. This file provides a
way to expose those functions in a way that makes it clear
this is a private/hidden api.

The iana_afi_t and iana_safi_t were being created in zebra.h
and zebra.h is a bit of a dumping ground. When the iana_afi2str and
iana_safi2str functions were created, it was correctly pointed out
that we should just use the internal afi_t and safi_t 2str functions
but to do that we would need to include prefix.h in zebra.h. Which
really is not the right thing to do. This tells us that we need
to break out this code into it's own header.
Move to iana_afi.h the enums and specific functions and remove
from zebra. Convert to using the afi2str and safi2str functions.

If --command-log-always is specified then all commands are
auto-logged and the 'no log commands' form of the command
is now ignored.

Each of Lua's major versions are incompatible with each other. Ubuntu,
at least, does not provide a single liblua.so or /usr/include/lua; all
SOs and headers are versioned, e.g. liblua5.3.so and
/usr/include/lua5.3. There's already an m4 macro in the GNU collection
to handle this situation, so let's use that.
This allows building with Lua enabled to work on platforms other than
Fedora.
* Move lib/lua.[ch] -> lib/frrlua.[ch] to prevent path conflicts
* Fix configure.ac search for proper CPP and linker flags

Typesafe red-black tree, built out of the OpenBSD implementation and the
macro soup layered on top. API compatible with skiplists & simple
lists.
Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
By the power of the C preprocessor, these macros provide type-safe
warppers for simple lists, skiplists and hash tables. Also, by changing
the instantiation macro, it is easily possible to switch between
algorithms; the code itself does not need to be changed since the API
is identical across all algorithms.

be integrated into mlag.
Zebra and Pim will both need mlag state for the router. As such we will
need to provide a abstract about this state through the zapi.

This bakes our YANG models straight into the library/daemons, so they
don't need to be loaded from /usr/share/yang. This makes the
installation quite a bit more robust, as well as gets us halfway to
running uninstalled. (The other half is baking in the extension type
module.)
The /usr/share/yang directory is still searched as a fallback, as well
as for the experimental YANG model translator. This is likely to stay
as is for the time being.

This commit introduces lib/id_alloc, which has facilities for both an ID number
allocator, and less efficient ID holding pools. The pools are meant to be a
temporary holding area for ID numbers meant to be re-used, and are implemented
as a linked-list stack.
The allocator itself is much more efficient with memory. Based on sizeof
values on my 64 bit desktop, the allocator requires around 155 KiB per
million IDs tracked.
IDs are ultimately tracked in a bit-map split into many "pages." The
allocator tracks a list of pages that have free bits, and which sections
of each page have free IDs, so there isn't any scanning required to find
a free ID. (The library utility ffs, or "Find First Set," is generally a
single CPU instruction.) At the moment, totally empty pages will not be
freed, so the memory utilization of this allocator will remain at the
high water mark.
The initial intended use case is for BGP's TX Addpath IDs to be pulled
from an allocator that tracks which IDs are in use, rather than a free
running counter. The allocator reserves ID #0 as a sentinel value for
an invalid ID numbers, and BGP will want ID #1 reserved as well. To
support this, the allocator allows for IDs to be explicitly reserved,
though be aware this is only practical to use with low numbered IDs
because the allocator must allocate pages in order.

The frr-interface YANG module models interfaces using a YANG list keyed
by the interface name and the interface VRF. Interfaces can't be keyed
only by their name since interface names might not be globally unique
when the netns VRF backend is in use. When using the VRF-Lite backend,
however, interface names *must* be globally unique. In this case, we need
to validate the uniqueness of interface names inside the appropriate
northbound callback since this constraint can't be expressed in the
YANG language. We must also ensure that only inactive interfaces can be
removed, among other things we need to validate in the northbound layer.
