fd1293ba31 I'm happy to finally commit stephen@'s implementations of cacos,
cacosh, casin, casinh, catan, and catanh. Thanks to stephen@ and bde@
for working on these.

baa7787a16 Add C11 macros CMPLX(), CMPLXF() and CMPLXL().
Clang allows us to initialize complex numbers using an array
initializer, casted to a complex type. GCC has a builtin called
__builtin_complex().

7b66fc7484 Make _Complex_I a proper float _Complex when using GCC 4.2.
It turns out our GCC has quite an interesting bug:

	typeof(1.0fi) != float _Complex
	typeof((float _Complex)1.0fi) != float _Complex
	typeof((float _Complex)1.0i) == float _Complex

In other words: if casting to an equal size, GCC seems to take a
shortcut. By casting down from a double to a float, GCC doesn't take
this shortcut, yielding the proper type.

To prevent foot-shooting, add a _Static_assert() to guarantee that
_Complex_I is always a float _Complex. I'm not going to MFC this part of
the diff.

46d384e689 Add implementations for cimag{,f,l}, creal{,f,l} and conj{,f,l}. They are
needed for cases where GCC's builtin functions cannot be used and for
compilers that don't know about them.

f495b1e357 Remove the macros for creal{,f} and cimag{,f}. They failed to convert their
arguments to the needed type and so the result type depended on the argument
type.  Fixing them isn't really worth the effort because GCC emits the same
assembler code with or without them.

0d5bbb0349 Added skeleton <complex.h> (aligned with the POSIX.1-200x), mostly
to fix the "-nostdinc WARNS=X" breakage caused by broken prototypes
for cabs() and cabsl() in <math.h>.

Reimplemented cabs() and cabsl() using new complex numbers types and
moved prototypes from <math.h> to <complex.h>.
