720c4f7414 Fix return-type of fortified FD_CLR and FD_SET 
POSIX specifies them to have return-type void, not int.

c2bb9e106a 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().

9f8c543dc8 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.

4b4dfea25d Fix invalid conversion in C++ code 
/usr/include/fortify/string.h: In function 'void* __fortify_memcpy(void*, const void*, size_t)':
/usr/include/fortify/string.h:13:12: error: invalid conversion from 'void*' to 'char*' [-fpermissive]
/usr/include/fortify/string.h:14:18: error: invalid conversion from 'const void*' to 'const char*' [-fpermissive]

Since we are relying on GCC anyway, assume void * arithmetic is OK.
