include: Use __has_builtin to detect __builtin_offsetof support
The __has_builtin operator is more specific and is supported by GCC
and Clang, while __is_identifier() is less specific and only supported
by Clang, so we should prefer the former whenever it is available, and
only fallback to use the latter when the former is missing and the
latter.

Use uintptr_t and size_t instead of __-prefixed types in <sys/cdefs.h>
The __-prefixed types cannot be assumed to be defined. Use the standard
types instead.

Correct Clang feature detection
Clang's __GNUC__ and __GNUC_MINOR__ definitions are not reliable and may
not be defined at all when targeting the MSVC ABI. Use feature-checking
macros when possible or check for __clang__.

Fix function declaration protection for glibc already providing them
On non-glibc based systems we cannot unconditionally use the
__GLIBC_PREREQ macro as it gets expanded before evaluation. Instead,
if it is undefined, define it to 0.
We should also always declare these functions on non-glibc based
systems. And on systems with a new enough glibc, which provides these
functions, we should still provide the declarations if _GNU_SOURCE
is *not* defined.

Move overlay inclusions outside of header protection
Glibc tends to include standard headers with special definitions
that make few declarations or macros visible, this stomps over the
overlay #include_next <> logic.

Define _SYS_CDEFS_H and _SYS_CDEFS_H after including <sys/cdefs.h>
This makes sure the “standard” inclusion protectors are in place, as at
least some FreeBSD kernel headers expect these to be defined to do some
sanity checks.

Add support for transparent compilation
This means that software being ported should not need to be modified in
the usual case, as the libbsd headers will take over the standard
namespace and fill the missing gaps, and include the system headers.
To use this the new libbsd-transparent.pc file can be used through
pkg-config, which should end up doing the right thing.
