1e4920e080 memset: fix define usage for shared libs 
The proper define to check "am I in a shared lib" is "SHARED", not "PIC".
The two new memset_chk functions incorrectly depend on "PIC".

e80d6f94e1 Fix size parameter comparisions. 
[BZ #13592]
There are several signed compares of the size argument, whereas
it really is unsigned.  Depending on situations e.g. a "memset(ptr, 0,
-1)" segfault (but for the wrong reasons, because jumping into nirvana)
or succeeds even.

In normal use this is harmless, as a size with signbit set indicates
more than half the address space which on x86_64 is impossible to
allocate, but as the size is used to index some jump tables this
potentially could have other unwanted side effects.

b1aa60f32d Add __bswap_64 definition for non GCC compilers. 
[BZ#13926]
Currently __bswap_64 is not defined at all for non-GCC compilers.
Define it but guard it with __GLIBC_HAVE_LONG_LONG.

endian.h uses __bswap_64, make the functions only available
if __GLIBC_HAVE_LONG_LONG is defined.

call to __feraiseexcept.

4851a949b4 Make inline __isnan, __isinf_ns, __finite generic.

we define the fp word manipulation macros before including the
generic header.
