8824eace93 testautomation: Test SDL_snprintf() for doubles >LLONG_MAX and <ULLONG_MAX 
The uclibc version of SDL_snprintf() is currently limited to values
<ULLONG_MAX due to the `unsigned long long` cast in SDL_PrintFloat(),
but it makes sense to at least ensure that it does support the full
unsigned 64-bit range. This also covers the one defined case where a
32-bit MSVC build can't assume that _ftoul2_legacy() == _ftol2().

b713e7581b stdlib: fix SDL_strtol of "0" with base 0 
SDL_strtol("0") skipped the "0" octal prefix
and returned a failure because the remainder of the string was empty.

a90ad3b0e2 Removed SDL_bool in favor of plain bool 
We require stdbool.h in the build environment, so we might as well use the plain bool type.

If your environment doesn't have stdbool.h, this simple replacement will suffice:
typedef signed char bool;

90e01040c5 Added thread-safe environment functions 
Also marked the existing functions as unsafe, as they can cause crashes if used in multi-threaded applications.

As a bonus, since the new functions are hashtable based, hint environment lookups are much faster.
