The size is 120, close fit for 128 and rarely used. The infrequent use
avoidably populates per-CPU caches and ends up with more memory.

0f352f4e25 Re-implement comment parsing missing in the internal pre-processor
The internal pre-processor ignored lines that did not parse a calendar
entries, but did not support multi-line comments in the way the external
cpp did.

The calendar files distributed with the base system (now in a port) do
use comments, though.

Implement comment processing for single-line (//) and multi-line comments
(/* */) with same semantics as in a standard C pre-processor.

All tests pass with this version, but there are no tests that specifically
verify comment processing.

638000c0b6 Use public interfaces to manage the nested rate limit send tag.
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.

3fa2a149d6 Fix calendar -a processing of files included in the user's home directory
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.

521eac97f3 Support hardware rate limiting (pacing) with TLS offload.
- 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].

1ef64e3da5 loader: add aarch64 support for zstd
We don't have NEON available in the boot loader, so we have to disable

__ARM_NEON is the proper symbol, defined in ARM C Language Extensions
Release 2.1 (https://developer.arm.com/documentation/ihi0053/d/). Some
sources suggest __ARM_NEON__, but that's the obsolete spelling from
prior versions of the standard.

19b5c30754 Add support for nested conditionals
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.
