netstat: Add -F support for -g
This change adds the ability to examine the contents of multicast
routing tables for other FIBs without the need for executing
`netstat` with `setfib(1)`.

sound examples: Add mmap example
This example opens separate OSS capture and playback channels in mmap
mode, places them into a sync group, and starts them together so both
ring buffers advance on the same device timeline. It then monitors the
capture mmap pointer with SNDCTL_DSP_GETIPTR, converts that pointer into
monotonic absolute progress using the reported block count, and copies
newly recorded audio from the input ring to the matching region of the
output ring.
The main loop is driven by an absolute monotonic frame clock rather than
a fixed relative usleep delay. Wakeups are scheduled from the sample
rate using a small frame step similar to the SOSSO timing model, while
the audio path itself stays intentionally simple: just copy input to
output, with no explicit xrun recovery or processing beyond ring
wraparound handling.

if_bridge(4): don't sleep under epoch(9) in destruction
bridge tries to run callout_drain(9) twice under epoch
during destruction.
once for bridge_timer, which is not required to be under epoch.
second time for the BSTP callout, which is already disabled
earlier inside bridge_delete_member.

routing: Fix use-after-free in finalize_nhop
FIB_NH_LOG calls the `nhop_get_upper_family(nh)` to read
`nh->nh_priv->nh_upper_family` for failure logging.
Call FIB_NH_LOG before freeing nh so failures are logged
without causing a panic.

sound: Retire unused CHN_N_* defines
These still haven't been implemented by the original author, and there
doesn't seem to be much use for them anyway.

iflib: drain admin task and fix teardown order on register failure
When IFDI_ATTACH_POST() fails (or netmap attach fails), iflib tears down with
ether_ifdetach(), taskqueue_free(ifc_tq), and IFDI_DETACH(). CTX_LOCK is still
held after ether_ifattach. ether_ifdetach() and taskqueue_drain(admin) must not
run under CTX_LOCK.
Teardown ordering (match iflib_device_deregister):
- Free the per-interface admin taskqueue after IFDI_DETACH / IFDI_QUEUES_FREE, not before.
- Drop IFNET_WLOCK() across IFDI_DETACH / IFDI_QUEUES_FREE so driver detach can sleep in
LinuxKPI workqueue drain, then retake IFNET_WLOCK() before iflib_free_intr_mem and fail_unlock.

misc/claude-code: Add option USE_CURL_USER_AGENT
Problem:
Certain URLs reject requests from AI agents like Claude.
Example is https://bugs.freebsd.org.
Solution:
The USE_CURL_USER_AGENT option will make Claude to look like Curl.
Benerits to the user:
Claude will be able to read such URLs, summarize their content,
or perform other actions with the contents.
This makes Claude more usable when it comes to such protected URLs.
How it works:
Claude's Fetch tool uses the rgq() function in cli.js which returns:
Claude-User (claude-code/2.1.105; +https://support.anthropic.com/)
This UA is explicitly blocked by Anubis bot protection on bugs.freebsd.org
