David 'Digit' Turner f8a2c51bf3 LONG_LONG_MIN/MAX: Move declarations to <limits.h>
LONG_LONG_MIN, LONG_LONG_MAX and ULONG_LONG_MAX are
GLibc-specific macros that are better defined in <limits.h>
instead of the current exotic location (<pthread.h>).

Note that GCC's <limits.h> only defines these macros
when __GNU_LIBRARY__ is also defined. This is only the
case when building against GLibc, so manually redefine
the macros here.

Note that using LLONG_MIN/LLONG_MAX/ULLONG_MAX is the
C99-compliant way to get these values, but it's easier
to define these compatibility macros for the sake of
porting existing code.
