Now that time_t is unconditionally 64-bit (signed int64_t) and the
struct timespec fields tv_sec / tv_nsec are wide enough on their own,
the explicit (uint64_t)/(int64_t)/(int) casts that used to guard the
multiplications and subtractions in *_us / *_ms / *_ns helpers are no
longer needed. Drop them to keep the timekeeping math readable.
In the same spirit, this commit also normalises the printf-style format
specifiers and casts used to print tv_sec / tv_nsec / tv_usec values.
The prior code was a mix of "%d"/"%u"/"%ld"/"%lu"/"%lld" with matching
(int)/(unsigned long)/(long long) casts; some formats truncated time_t
on 32-bit hosts, others mismatched signedness or width. Replace all
such cases with the portable POSIX-recommended forms:
- tv_sec (time_t, signed, impl-defined width) -> %jd + (intmax_t)
- tv_nsec (long, signed) -> %ld (no cast)
- tv_usec (suseconds_t / long) -> %ld (no cast)
Also drop two stale `(FAR const time_t *)&ts.tv_sec` casts that are
unnecessary now that ts.tv_sec is plain time_t.

The matching nuttx commit removes CONFIG_HAVE_LONG_LONG; clean up the
remaining users in nuttx-apps so that "long long" is always assumed:
- examples/noteprintf, examples/nxscope:
unconditionally exercise the %lld / long long branch.
- fsutils/mkfatfs/configfat.c:
drop the 32-bit fall-back paths in mkfatfs_nfatsect12/16/32;
always use uint64_t for the FAT-size arithmetic.
- logging/nxscope/nxscope_chan.c:
drop the CONFIG_HAVE_LONG_LONG guard around the 64-bit
sample helpers.
- netutils/ftpd, netutils/ntpclient:
always emit the 64-bit format strings.
- testing/fs/fstest/fstest_main.c:
drop the parallel 32-bit verification path; keep only the
64-bit (long long) random pattern generator.
- system/zmodem/host/nuttx/compiler.h:
remove the host-side CONFIG_HAVE_LONG_LONG stub macro.

Use the DHCP-learned NTP server list as the default ntpc server source when DHCP option 42 is available.
Fall back to CONFIG_NETUTILS_NTPCLIENT_SERVER only when DHCP does not provide any NTP servers, and restart ntpc when the DHCP-provided server list changes.

The current calculation easily overflows if the local time is
around the unix epoch. I guess it isn't too unusual for
devices without RTC. Or, the battery is dead. Or, whatever.
This commit avoids the overflow by simply dividing everything by 2.
While more sophisticated and precise solutions are possible,
I feel that they are overkill for this simple implementation.
For example,
The unix epoch (1970) is 0x83aa7e8000000000 in
64-bit NTP timestamp. (1900-origin)
The timestamp now, as of writing this, is 0xe3cda16b00000000.
With the code before this commit, the offset will be:
(lldb) p (long long)((0xe3cda16b00000000 - 0x83aa7e8000000000) + (0xe3cda16b00000000 - 0x83aa7e8000000000)) / 2
(long long) $16 = -2295952992316162048
(lldb)
with the new code, it would be:
(lldb) p (long long)((0xe3cda16b00000000 / 2 - 0x83aa7e8000000000 / 2) + (0xe3cda16b00000 / 2 - 0x83aa7e8000000000 / 2))
(long long) $17 = 6927419044538613760
(lldb)
It's the correct offset from the unix epoch:
(lldb) p 6927419044538613760 >> 32
(long) $0 = 1612915435
(lldb)
