Implemented posix_getspnam() function

[igmar]

Added posix_getspnam() function to the posix extension.

Shouldn't there be a test for HAVE_SHADOW_H here instead? (or as well?)

[igmar]

AC_CHECK_FUNCS() should take care of that. You either have it and it's in shadow.h, or you don't. I haven't seen it done in a different way. It's not POSIX, so we might run into other implementations.

[dsp]

getspwnam is not part of the POSIX.1, POSIX.1b or POSIX.1c standard.

From the Linux Manpages:

CONFORMING TO
The shadow password database and its associated API are not specified in POSIX.1-2001. However, many other systems provide a similar API.

I'm not sure if this should belong to ext/posix, but then on the other hand there is no suitable other extension to add this function too.

[igmar]

The reason I've put it in ext/posix because similar functions are also in that extension. It's not POSIX, I agree, but it also serves special use cases. It's harmless in all other cases.

[dsp]

in case you have ZTS and GETSPANAM_R so

#if defined(ZTS) && defined(HAVE_GETSPNAM_R)

get's execute you have buf allocated. In case php_posix_spwd_to_array fails you are not
freeing buf anymore.
