Fix Clang warnings on Windows

- Align DLLEXPORT in definitions and declations. There is still a few
cases left, where the declation in the compiler's complex.h disagrees
with the implementation here. For now we can't do anything about that,
but maybe should be revisited in the future.
- Fix the syntax on an .ascii directive that gcc accepted mistakingly, but
clang does not.

Rename _scan_nan() to __scan_nan().

The current tradition of openlibm is to hide all of its internal symbols
into the reserved system namespace. CloudABI has a check in place to
ensure that its C library (which contains openlibm) to not place any
unwanted symbols into the public namespace. openlibm seems to leak
_scan_nan() in there, so we'd better add an additional underscore.

Remove __always_inline, just like we do for ld80.

__always_inline is a (Free)BSD specific definition from cdefs.h.
Compilers like Clang don't care about these keywords anyway, as they
simply do whatever they like.

It looks like we already removed this keyword from ld80/e_rem_pio2l.h as
well. Apply exactly the same change to the ld128 version as well.

Use isfinite() instead of non-standard finite() function.

The finite() function got standardized under the name isfinite(). Its
use is therefore discouraged.

Rename openlibm.h to openlibm_math.h.

This is a bit more consistent with the naming of the other header files
(openlibm_complex.h and openlibm_fenv.h). Re-add an openlibm.h header
that includes all of the public headers as a shorthand.

Fix up all of the source files to include <openlibm_math.h> instead of
<openlibm.h>. While there, fix ordering of the includes.

Add lgammal_r().

We already provide lgammaf_r() and lgamma_r(). It's not hard to also add
lgammal_r(), for consistency.

I am currently working on porting openlibm to an environment where
global state, and thus signgam, is not available. By adding lgammal_r(),
I can trivially disable support for signgam by just patching up
src/e_lgamma{f,,l}.c. That way there is no need to patch up the actual
algorithms.

Don't let tgammal() modify signgam. Only lgamma*() should modify it.

Letting tgammal() modify signgam has two disadvantages:

- It breaks valid code that assumes that the value of signgam is not
clobbered by calls to tgammal().
- It makes this function depend on the presence of signgam. signgam is
an X/Open System Interface. It is not part of the C standard.
