fix signed range problems with hex conversions
Make hexval_table[] "const". Also make sure that the accessor function hexval() does not access the table with out-of-range values by declaring its parameter "unsigned char", instead of "unsigned int". With this, gcc can just generate: movzbl (%rdi), %eax movsbl hexval_table(%rax),%edx movzbl 1(%rdi), %eax movsbl hexval_table(%rax),%eax sall $4, %edx orl %eax, %edx for the code to generate a byte from two hex characters.
