This avoids unconditionally using clock_gettime in
{ecc,hogweed}-benchmark, falling back to clock() in these
as well.

This makes building succeed on e.g. OS X.

(time_cipher): Also benchmark CTR mode.

(time_gmac): ...old name.

(cgt_time_start): Likewise.
(cgt_time_end): Likewise.
(clock_time_start): Likewise.
(clock_time_end): Likewise.
(time_function): Read clock via function pointers time_start and
time_end, so we can select method at runtime.
(xalloc): Use die function.
(main): Choose timing function. If available, try clock_gettime,
and fall back to clock if it doesn't exist.

(main): Use time_memxor. Added optional argument used to limit the
algorithms being benchmarked.

(time_function): Use clock_gettime with CLOCK_PROCESS_CPUTIME_ID,
if available. This gives better accuracy, at least on recent
linux.
