The current code only decodes TFD_TIMER_ABSTIME when the kernel has
a bunch of newer flags. We have to handle fallbacks for all of them
since the kernel doesn't currently export things to userspace.
* time.c: Include fcntl.h for O_* defines.
(TFD_TIMER_ABSTIME): Move to xlat/timerfdflags.in.
* xlat/timerfdflags.in: Add more definitions.
Since parsers for stime and time syscalls are identical,
replace sys_stime with an alias to sys_time.
* linux/dummy.h (sys_stime): Alias to sys_time.
* linux/syscall.h (sys_stime): Remove.
* time.c (sys_stime): Remove.
Automatically update all xlat structures using the following sed regexp:
s/^[[:space:]]*{[[:space:]]*0[[:space:]]*,[[:space:]]*NULL[[:space:]]*,\?[[:space:]]*}[[:space:]]*,\?[[:space:]]*/\tXLAT_END/
Automatically convert all xlat structures to XLAT form
using the following sed regexp:
s/^[[:space:]]*{[[:space:]]*\([^",}[:space:]]\+\)[[:space:]]*,[[:space:]]*"\1",\?[[:space:]]*}[[:space:]]*/\tXLAT(\1)/
* time.c (cpuclocknames): New xlat structure.
(printclockname): New function that decodes posix clock names,
including dynamic fd encoded clocks.
(sys_clock_settime, sys_clock_gettime, sys_clock_nanosleep,
sys_clock_adjtime, sys_timer_create, sys_timerfd, sys_timerfd_create):
Use it.

SIGEV_THREAD_ID decoding requires access to an internal member of
struct sigevent. There seems to be no portable way to do it besides
adding a configure check.
* configure.ac (AC_CHECK_MEMBERS): Check for
struct sigevent._sigev_un._pad and struct sigevent.__pad.
* time.c (printsigevent): Use an appropriate struct sigevent member
to print thread id.

The files not mentioned in changelog below had only
copyright notices fixes and indentation fixes.
* defs.h: Include <stdint.h> and <inttypes.h>.
* file.c: Do not include <inttypes.h>.
Move struct kernel_dirent declaration below top include block.
* block.c: Do not include <stdint.h> and <inttypes.h>.
* quota.c: Likewise.
* desc.c: Likewise.
* signal.c: Likewise.

* linux/dummy.h (sys_clock_adjtime): Remove.
* linux/syscall.h (sys_clock_adjtime): New prototype.
* time.c (do_adjtimex): New function, based on sys_adjtimex.
(sys_adjtimex): Use it.
(sys_clock_adjtime): New function.
Conditions such as defined(LINUX) are always true now,
defined(FREEBSD) etc are always false.
When if directive has them as subexpressions, it can be simplified.
Another trivial changes here are fixes for directive indentation.

* defs.h: Add TIMESPEC_TEXT_BUFSIZE and TIMEVAL_TEXT_BUFSIZE defines.
Add 'int special' parameter to sprinttv().
* time.c (sprinttv): Add 'int special' parameter, and use it
similarly to 'int special' parameter of printtv_bitness().
(printtv_bitness): Use sprinttv() instead of duplicating its code.
(print_timespec): Use sprint_timespec() instead of duplicating
its code.

After this change, we don't use strcat() anywhere.
* defs.h: Change sprinttv() return type to char *.
* time.c (sprinttv): Return pointer past last stored char.
* desc.c (decode_select): Change printing logic in order to eliminate
usage of strcat() - use stpcpy(), *outptr++ = ch, sprintf() instead.
Also reduce usage of strlen().
* stream.c (decode_poll): Likewise.
