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.

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.
