  ENH: Detect all functions in complex.h

Set the HAVE_XXXX macros for all of the following functions.

    csin,   ccos,   ctan
    casin,  cacos,  catan
    csinh,  ccosh,  ctanh
    casinh, cacosh, catanh
    cexp,   clog,   cpow
    cabs,   csqrt,  carg
    cimag,  creal,  conj,
    cproj

The macros do not need to be used, but it is good to have all of
them available.

The new functions added:

    npy_ctan,
    npy_cacos, npy_casin, npy_catan
    npy_ccosh, npy_csinh, npy_ctanh
    npy_cacosh, npy_casinh, npy_catanh

  ENH: Use the new complex functions in npymath for our ufuncs.

This should clear up such things as

>>> np.tanh(372 + 1j)
(nan+nan*j)

  TST: Add tests for complex ufuncs.

The test for precision needed to have difference changed from 2*eps to
2.1*eps for the system supplied sinh.

  Log Message:
  -----------
  BUG: Do not use system cpow directly.

Numpy computes small integer powers by multiplication, this leads to
different results than the system cpow for such integers. In particular,
cpow((0 + inf*1j), 2) returns (-inf + 0j) rather than (-inf + nanj). The
system version probably makes more sense, but better to keep
compatibility at this point. We could fix our results using cproj.

  BUG: Disable broken complex trig functions for early linux glibc.

The library functions casin, casinh, catan, catanh are inaccurate
in glibc version < 2.16, so use the numpy fallback functions for
those.
