Add missing <complex.h> functions.

FreeBSD doesn't seem interested in having low-quality implementations of
these functions:

  cacoshl, cacosl, casinhl, casinl, catanhl, catanl, ccoshl, ccosl, cexpl,
  clog, clogf, clogl, cpow, cpowf, cpowl, csinhl, csinl, ctanhl, ctanl.

And they still haven't got round to writing good implementations, so for
now let's just take the NetBSD ones so we have the full set.

Bug: http://b/27555792
