c47b1e2c5b !sys/types.h: change time_t and clock_t to int64_t to align with other OSes 
POSIX leaves the signedness of time_t and clock_t unspecified, but
mainstream implementations (Linux glibc/musl, the BSDs, macOS, RTEMS,
Zephyr's POSIX layer, Windows _time64) expose time_t as signed 64-bit.
NuttX has historically used uint64_t only because it was tied to the
CONFIG_SYSTEM_TIME64 knob; with that gone, switch:

  time_t   : uint64_t  -> int64_t
  clock_t  : uint64_t  -> int64_t
  CLOCK_MAX: UINT64_MAX -> INT64_MAX

This lets (time_t)-1 sentinels, negative tick deltas, and host-side
headers behave as on every other POSIX system without source churn.

Headers updated:
  - include/sys/types.h, include/limits.h, include/nuttx/clock.h
  - include/nuttx/fs/hostfs.h (nuttx_time_t alias)
  - include/nuttx/{mqueue.h,wdog.h,wqueue.h,timers/clkcnt.h}

Because clock_t is now signed 64-bit, the NuttX-internal sclock_t
alias becomes redundant: every sclock_t/SCLOCK_MAX use is folded
back to clock_t/CLOCK_MAX (notably in sched/wdog, sched/mqueue,
sched/sched, sched/clock, sched/timer, libs/libc/time, fs/vfs and
the drivers/arch consumers below).

Tick/period constants (NSEC_PER_SEC, USEC_PER_SEC, MSEC_PER_SEC,
SEC_PER_MIN, ...) in include/nuttx/clock.h are retyped from "long"
literals to INT64_C(...) so that 64-bit arithmetic no longer
depends on the host's long width.

Strip now-redundant (time_t)/(clock_t)/(unsigned long) casts and
unsigned-only branches across the tree:
  - arch RTC / oneshot / tickless lowerhalfs:
      arm: cxd56xx, efm32, imxrt, lc823450, max326xx, sam34, sama5,

           esp32c3{_i2c,_rtc,_wifi_adapter}, esp32{,s2,s3}_*),
           mpfs_perf
  - drivers: audio/tone, input/aw86225, power/pm/{activity,
           stability}_governor, rpmsg/rpmsg_ping,
           timers/{ds3231,mcp794xx,pcf85263,rx8010},
           wireless/ieee80211/bcm43xxx, wireless/spirit/spirit_spi
  - core: fs/vfs/{fs_poll,fs_timerfd}, mm/iob/iob_alloc,
          libs/libc/{netdb/lib_dnscache,time/{lib_calendar2utc,
          lib_time}}, net/icmp/icmp_pmtu, net/icmpv6/icmpv6_pmtu,
          net/ipfrag, net/tcp/{tcp.h,tcp_timer},
          net/utils/net_snoop, net/mld/mld_query (drop the now-dead
          mld_mrc2mrd helper since signed math handles it directly),
          sched/clock/{clock,clock_initialize},
          sched/sched/{sched_profil,sched_setparam,sched_setscheduler},
          sched/pthread/pthread_create,
          sched/wdog/{wd_gettime,wd_start,wdog.h},
          sched/timer/timer_gettime, sched/mqueue/*

Flip the few in-tree printf format strings that assumed an
unsigned 64-bit tv_sec:
  * drivers/rpmsg/rpmsg_ping.c                       PRIu64 -> PRId64
  * arch/xtensa/src/esp32{,s2,s3}/esp32*_oneshot_lowerhalf.c
                                          PRIu32 (already wrong) -> PRId64

0dccc8ba21 include/debug.h: Move to include/nuttx/debug.h 
debug.h is a NuttX-specific, non-POSIX header. Placing it in the
top-level include/ directory creates naming conflicts with external
projects that define their own debug.h.
This commit moves the canonical header to include/nuttx/debug.h,
following the NuttX convention for non-POSIX/non-standard headers,
and updates all in-tree references.

A backward-compatibility shim is left at include/debug.h that
emits a deprecation #warning and re-includes <nuttx/debug.h>,
allowing out-of-tree code to continue building while migrating.

8a3fc26b74 Squashed commit of the following: 
The MLD implementation did not follow the RFC correctly when it is the Querier.  The Querier should use a general query and get query messages from all members of all groups.  This would be driven by a single timer per sub-nset since all groups are queried at once. Instead, the design used a Multicast Address Specific Query with one timer per group and ignores groups that we are not members of.

    Similary, the MLDv1 compatibility timer should be a single, separate timer, not a per-group timer.

    net/mld:  Implement 'Other Querier Present Timer'.  This timer is used to revert to Querier mode if there is no other querier on the network.  Also, fix some naming:  The Done message is not just Version 1 but is used with Version 2 as well.

    net/igmp:  Back out some blind, backported improvements to IGMP from MLD.  There are too many subtle differences in the protocols for this to be safe.

net/mld: Checksum calculation needs to know the full size of the IPv6 header, including the size of the extension headers.  The payload size in the IPv64 header must include the extension headers (not considered part of the header in this case).  Fixes a few additional errors in size, endian-ness and checksum calculations.  Wireshark now reports the the outgoing Report has a good checksum.

5b7ef856a0 Squashed commit of the following: 
net/mld:  The MLD logic now compiles and is much less toxic.  It still is not a proper MLD implementation:  (1) It is basically a port of IGMP, tweaked to work with IPv6 and ICMPv6 MLD messages, (2) it needs a proper analysis and comparison with RFC 3810, and (3) it is completely untested.  For this reason, it will remain EXPERIMENTAL for some time.
    net/mld:  Add some missing macros, more fixes related to IPv6 vs IPv4 types,
    net/mld:  More compilation cleaning.  Most fixups for IPv6 vs IPv4 types.
    net/mld:  Hook crudely converted .c files into build system and resolve a few of the many, many compilation/design problems.
    net/mld:  Add support for MLD statistics.
    net/mld:  Hook in MLD poll and packet transmission logic.
    net/mld:  Change references to IPv4 definitions to IPv6 definitions; Remove mld_input() since MLD piggybacks on ICMPv6 input.  Add functions to catch MLD messages dispatched by ICMPv6 input logic.
    net/mld:  As a starting point, copy all net/igmp/*.c files to net/mld/. and change all occurrences of igmp (or IGMP) to mld (or MLD).
