fix realpath when stdlib.h is included before limits.h
...
If program includes stdlib.h before limits.h without _XOPEN_SOURCE,
_GNU_SOURCE or _BSD_SOURCE explicitly set, then will it always trigger
the trap with musl libc.
This is becase stdlib.h will pull in features.h which will set
_GNU_SOURCE. This means that the fortify stdlib.h will not include
limits.h but it will still trigger the fortified realpath(), but without
PATH_MAX set.
We fix this by including system stdlib.h before testing if limits.h
should be included.
Since PATH_MAX is known at compile time we can also error at compile
time, instead of compiling a broken realpath().

Rework fortify implementation to use extern inline
...
Overriding functions with macros is legal in C but a lot of software
is not prepared for it. Use the extern inline method to achieve the
same result.

It is not legal to override standard functions using macros in C++.
