ac42add946 nuttx/clock: make NSEC_PER_USEC and others long
On AVR architecture, the compiler apparently sometimes truncates NSEC_PER_TICK
to 16bit value, leading to clock_time2ticks returning incorrect results. This
was encountered while attempting to add tickless OS support for AVR
architecture but seemed to affect non-tickless mode of operation as well.

This patch marks NSEC_PER_USEC (and to be safe, USEC_PER_MSEC and MSEC_PER_SEC
too) as long.

3b111c8b99 sched/wdog: Refactor wdog module
This commit refactors the wdog module to use absolute time representation internally. The main improvements include:
1. Fixed recursive watchdog handling caused by calling wd_start within watchdog timeout callback function.
2. Simplified timer processing to improve performance and enhance code readability.
3. Improved accuracy of timers.
4. Reduced critical section and interrupt disable time, improving real-time performance.

include/nuttx/clock.h:

    * USEC_PER_TICK: The docstring for this define mistakenly said
      that the default value of USEC_PER_TICK, 10000, corresponded
      to 100 KHz. However, it is actually 100 Hz. Corrected the
      comment. No functional changes.

83745652c4 TCP-stack fix for stalled tcp sockets due to broken keepalive
Fixes an issue where tcp sockets with activated keepalives stalled and
were not properly closed. Poll would not indicate a POLLHUP and therefore
locks down the application.

* tcp_conn_s.tcp_conn_s & tcp_conn_s.keepintvl changed to uint32_t
  According RFC1122 keepidle MUST have a default of 2 hours.

153eee6de2 Make more OS internal names consistent
1. Internal scheduler functions should begin with nxsched_, not sched_
2. Follow the consistent naming patter of https://cwiki.apache.org/confluence/display/NUTTX/Naming+of+OS+Internal+Functions

    # clock_systimer -> clock_systime_tick
    # clock_systimespec -> clock_systime_timespec
    sched_oneshot_extclk -> nxsched_oneshot_extclk
    sched_period_extclk -> nxsched_period_extclk
    # nxsem_setprotocol -> nxsem_set_protocol
    # nxsem_getprotocol -> nxsem_get_protocol
    # nxsem_getvalue -> nxsem_get_value
    nxsem_initholders -> nxsem_initialize_holders
    nxsem_addholder -> nxsem_add_holder
    nxsem_addholder_tcb -> nxsem_add_holder_tcb
    nxsem_boostpriority -> nxsem_boost_priority
    nxsem_releaseholder -> nxsem_release_holder
    nxsem_restorebaseprio -> nxsem_restore_baseprio

Some planned name changed were skipped for now because they effect too many files (and would require many hours of coding style fixups).
