Log message:
net/mosquitto: Fix capath in example config

capath being set without cert/key is an error, and thus should not be
on in a default config.

Clean up old comments about the config file.  (The syslog/pidfile plan
has been working for years with no complaints.)

Log message:
net/mosquitto: Update to 2.0.21

Upstream changes, less bugfixes and non-pkgsrc platforms.

2.0.21 - 2025-03-06
===================

Security:
- Fix leak on malicious SUBSCRIBE by authenticated client.
  Closes eclipse #248.
- Further fix for CVE-2023-28366.

Broker:
- Add `retain_expiry_interval` option to fix expired retained message not
  being removed from memory if they are not subscribed to. Closes #3221.

Apps:
- mosquitto_ctrl dynsec now also allows `-i` to specify a clientid as well as
  `-c`. This matches the documentation which states `-i`. Closes #3219.

Log message:
net/mosquitto: Drop patch superceded by upstream

Long ago, upstream didn't include strings.h, but used strcasecmp, and
a patch added the include.  Now, upstream includes strings.h except on
WIN32 (presumably because it's not POSIX), and the extra include is
pointless.

Log message:
net/mosquitto: rm correct patch file

Log message:
net/mosquitto: gc support for NetBSD before 6

mosquitto uses strnlen, which is required by POSIX.1-2008, but did not
appear in NetBSD before 6.  Because NetBSD 5 is ancient, and much
older than 8, the oldest version formally supported, drop the patch as
costing more in cognitive load than it helps, guessing there are zero
people benefiting

Log message:
net/mosquitto: Update to 2.0.20

packaging changes:
  Drop patch-FIX (upstream pthreads fix now in a release)
  Drop patch-config.h (visibility define fix applied upstream)

Upstream NEWS: bug fixes

Log message:
net/mosquitto: GC workaround for libwebsockets cmake bug

libwebsockets now installs a more reasonable cmake file for use by
depending packages.  Don't worry about requiring the new version,
because the problem was most likely just a warning anyway.

net/mosquitto: Fix patch and distinfo from previous
