9b543ffeac cdefs.h: add artificial attribute to FORTIFY_SOURCE functions
Otherwise the gcc compiler warning doesn't show up.

Delete some unittests. These unittests no longer compile cleanly
using -Wall -Werror, and rewriting them to compile cleanly
isn't feasible.

a508714800 Reimplement clock(3) using clock_gettime(3)
Unlike times(), clock_gettime() is implemented as a vDSO on many architectures.
So, using clock_gettime() will return a more accurate time and do so with less
overhead because it does have the overhead of calling into the kernel.

It is also significantly more accurate because it measures the actual time in
nanoseconds rather than the number of ticks (typically 1 millisecond or more).

f4cb631364 Add IFUNC support for arm64 and IRELATIVE reloc
There are number of changes in the way IFUNC related relocations are done:
 1. IRELATIVE relocations are now supported for x86/x86_64 and arm64.
 2. IFUNC relocations are now relying on static linker to generate
    them in correct order - this removes necessety of additional
    relocation pass for ifuncs.
 3. Related to 2: rela?.dyn relocations are preformed before .plt ones.
 4. Ifunc are resolved on symbol lookup this approach allowed to avoid
    mprotect(PROT_WRITE) call on r-x program segments.

d18205049d Update bionic to tzdata 2014h.
From the release notes:

  Changes affecting past time stamps

    America/Jamaica's 1974 spring-forward transition was Jan. 6, not Apr. 28.

    Shanks says Asia/Novokuznetsk switched from LMT (not "NMT") on 1924-05-01,
    not 1920-01-06.  The old entry was based on a misinterpretation of Shanks.

    Some more zones have been turned into links, when they differed
    from existing zones only for older time stamps.  As usual,
    these changes affect UTC offsets in pre-1970 time stamps only.
    Their old contents have been moved to the 'backzone' file.
    The affected zones are: Africa/Blantyre, Africa/Bujumbura,
    Africa/Gaborone, Africa/Harare, Africa/Kigali, Africa/Lubumbashi,
    Africa/Lusaka, Africa/Maseru, and Africa/Mbabane.
