- Cleanup dl-vdso.c code.
- Pass `void *` as first arg to `load_vdso()`, using 32-bit type
is completely wrong on 64bit architectures.
- Split libc code and vDSO-related code.
Move arch-specific implementations into separate files.
The performance improvement is for example 50-60 times on ARMv7
and about 4 times on x86_64.

This patch introduces *time64 syscalls support for uClibc-ng.
Currently the redirection of syscalls to their *time64
analogs is fully supported for 32bit ARM (ARMv5, ARMv6, ARMv7).
The main changes that take effect when time64 feature is enabled are:
- sizeof(time_t) is 8.
- There is a possibility os setting date beyond year 2038.
- some syscalls are redirected:
clock_adjtime -> clock_adjtime64
clock_getres -> clock_getres_time64
clock_gettime -> clock_gettime64
clock_nanosleep -> clock_nanosleep_time64
clock_settime -> clock_settime64
futex -> futex_time64
mq_timedreceive -> mq_timedreceive_time64
mq_timedsend -> mq_timedsend_time64
ppoll -> ppoll_time64
pselect6 -> pselect6_time64
recvmmsg -> recvmmsg_time64
rt_sigtimedwait -> rt_sigtimedwait_time64
sched_rr_get_interval -> sched_rr_get_interval_time64
semtimedop -> semtimedop_time64
timer_gettime -> timer_gettime64
timer_settime -> timer_settime64
timerfd_gettime -> timerfd_gettime64
timerfd_settime -> timerfd_settime64
utimensat -> utimensat_time64.
- settimeofday uses clock_settime (like in glibc/musl).
- gettimeofday uses clock_gettime (like in glibc/musl).
- nanosleep uses clock_nanosleep (like in glibc/musl).
- There are some fixes in data structures used by libc and kernel
for correct data handling both with and without enabled time64 support.

applications stop using _syscall#() and use syscall() instead. Cleanup
internal handling of syscall includes to use the correct header file.

defined, gettimeofday has other prototype and tm_gmtoff/tm_zone do not exist

missing headers, other jump relocs removed

adding cruft to include/sys/time.h. But also, there's no sense in
making changes like this until we decide how we're going to approach
the hidden symbol transition.

Hello!
Would the attached patch be acceptable (maybe instead of
__libc_gettimeofday using __gettimeofday)
We have some issues, see
http://bugs.gentoo.org/show_bug.cgi?id=65892
