Each TLS send tag in mlx5 contains a nested rate limit send tag.
Previously, the driver was calling internal functions to manage the
nested tag. Calling free methods directly instead of m_snd_tag_rele()
leaked send tag references and references on the ifp. Changes to use
the ifp methods for the nested tag for other methods are more cosmetic
but do simplify the code.

struct nameidata mixes caller arguments, internal state and output, which
can be quite error prone.
Recent addition of valdiating ni_resflags uncovered a caller which could
repeatedly call namei, effectively operating on partially populated state.
Add bare minimium validation this does not happen. The real fix would
decouple aforementioned state.

The existing code performed a chdir() into the home directory, but the
parser fell back to using the invoking user's home directory as the base
directory for the search for an include file.
Since use of the -a option is limited to UID==0, the directory searched
was typically ~root/.calendar, not the .calendar directory of the user
whose file is being processed.

It appears that booting FreeBSD from qemu's synthesized FAT filesystem
broke somehow in a recent qemu-devel update. qemu42 works so switch to
it for now.
- Add a new send tag type for a send tag that supports both rate
limiting (packet pacing) and TLS offload (mostly similar to D22669
but adds a separate structure when allocating the new tag type).
- When allocating a send tag for TLS offload, check to see if the
connection already has a pacing rate. If so, allocate a tag that
supports both rate limiting and TLS offload rather than a plain TLS
offload tag.
- When setting an initial rate on an existing ifnet KTLS connection,
set the rate in the TCP control block inp and then reset the TLS
send tag (via ktls_output_eagain) to reallocate a TLS + ratelimit
send tag. This allocates the TLS send tag asynchronously from a
task queue, so the TLS rate limit tag alloc is always sleepable.
- When modifying a rate on a connection using KTLS, look for a TLS
send tag. If the send tag is only a plain TLS send tag, assume we
failed to allocate a TLS ratelimit tag (either during the
TCP_TXTLS_ENABLE socket option, or during the send tag reset
triggered by ktls_output_eagain) and ignore the new rate. If the
send tag is a ratelimit TLS send tag, change the rate on the TLS tag
and leave the inp tag alone.
- Lock the inp lock when setting sb_tls_info for a socket send buffer
so that the routines in tcp_ratelimit can safely dereference the
pointer without needing to grab the socket buffer lock.
- Add an IFCAP_TXTLS_RTLMT capability flag and associated
administrative controls in ifconfig(8). TLS rate limit tags are
only allocated if this capability is enabled. Note that TLS offload
(whether unlimited or rate limited) always requires IFCAP_TXTLS[46].

The previous behavior was to support nested #ifdef and #ifndef, but to
return to unconditional parsing after the next #endif, independently of
the number of previously parsed conditions.
E.g. after "#ifdef A / #ifdef B / #endif" the following lines were
unconditially parsed again, independently of A and/or B being defined.
The new behavior is to count the level of false conditions and to only
restart parsing of calendar entries when the corresponding number of
#endif tokens have been seen.
In addition to the above, an #else directive has been added, to toggle
between parsing and ignoring of the following lines.
No validation of the correct use of the condition directives is made.
#endif without prior #define or #ifndef is ignored and #else toggles
between parsing and skipping of entries.
The MFC period has been set to 1 month to allow for a review of the
changes and for a discussion, whether these modifications should not
be merged at all.
No correct input file is parsed differently than before, but if calendar
data files are published that use these new features, those data files
will not parse correctly on prior versions of this program.

The convention in this program is to parse the line immediately starting

There was code to process an #ifndef tokens, but none for #ifdef.
The #ifdef token was mentioned as unsupported in the BUGS section,
but no reason was given and I do not see why it should stay omitted.
Misleading information in The BUGS section of the man-page regarding
the maximum number of #define and #include statements supported has
been removed. These limits might have applied to a prior version of
this program, but do not seem to apply to the current implementation.
I have not tried to test for the existence of the limits, but the
include file processing just recursively calls the parser (without
counting the recursion depth) and the stringlist functions do not
impose a limit on the number of entries.

Installing the llvm11 package instead of bootstrapping it from the source
tree reduces the build time by about 20 minutes.
The last freebsd/freebsd build that was tested (r366629) took 1h 21m 22s,
whereas my GitHub fork with this .cirrus.yml took 58m 6s.
We could probably further reduce time by using images that have LLVM
pre-installed: the pkg install step took 4 minutes 30s.
Since the bootstrap toolchain is still tested by Jenkins, this should not
reduce test coverage of the CI testing.
