Every compiler supported by NuttX provides the "long long" types,
so the CONFIG_HAVE_LONG_LONG indirection is no longer useful.
Remove the option from include/nuttx/compiler.h and treat
"long long" as unconditionally available across the OS.
In addition to deleting the guard itself, this commit unconditionally
enables the long-long flavored helpers that used to be gated behind
it:
- libs/libc/fixedmath: drop the soft-emulated b32/ub32 routines
in lib_fixedmath.c (-261 lines) and trim the matching
prototypes, Make.defs and CMakeLists.txt entries; keep only
the long-long backed implementations.
- include/sys/endian.h, include/strings.h, libs/libc/string
/lib_ffsll.c, lib_flsll.c: always expose the 64-bit byte-swap
and ffsll/flsll variants.
- libs/libm/libm/lib_llround{,f,l}.c: drop the empty stubs.
- libs/libc/stdlib (atoll, llabs, lldiv, strtoll/ull, rand48,
strtold), libs/libc/stream (libvsprintf, libvscanf,
libbsprintf, ultoa_invert), libs/libc/misc (crc64, crc64emac),
libs/libc/inttypes/strtoimax, libs/libc/lzf, libs/libc/libc.csv,
libs/libc/string (memset, vikmemcpy): remove the
#ifdef CONFIG_HAVE_LONG_LONG branches.
- include/{stddef.h,stdlib.h,fixedmath.h,sys/epoll.h,cxx/cstdlib,
nuttx/audio/audio.h,nuttx/crc64.h,nuttx/lib/math.h,
nuttx/lib/math32.h,nuttx/lib/stdbit.h}: same guard cleanup.
- drivers/note/note_driver.c, fs/spiffs/src/spiffs.h,
sched/irq/irq_procfs.c: drop their local guards as well.
- Documentation/applications/netutils/ntpclient/index.rst:
refresh the documentation snippet.
