Lua replace fscanf
Rocklua was using the full fscanf implementation
to simply read %ld for the file:read("*n") function
wasting 1k on unneeded/unused functionality
Instead, I've implemented a filetol function to duplicate it
without the extra overhead using strtol which as an added bonus
ERANGE errors now resolve to LONG_MIN and LONGMAX instead of
integer overflow
filetol()
reads long int from an open file, skips preceding
whitespaces returns -1 if error, 1 on success.
*num set to LONG_MAX or LONG_MIN on overflow.
If number of digits is > than LUAI_MAXNUMBER2STR
filepointer will continue till the next non digit
but buffer will stop being filled with characters.
Preceding zero is ignored.
