Apart strict-aliasing warnings, fix the remaining warnings generated by GCC 4.4.4 -Wall and -Wextra flags. One major source of warnings was the in-house function my_bcmp which (unconventionally) took pointers to unsigned characters as the byte sequences to be compared. Since my_bcmp and bcmp are deprecated functions whose only difference with memcmp is the return value, every use of the function is replaced with memcmp as the special return value wasn't actually being used by any caller. There were also various other warnings, mostly due to type mismatches, missing return values, missing prototypes, dead code (unreachable) and ignored return values.
