Spring cleaning redux:

- Implemented changes suggested by Jilles
- Remove some unused parameters in functions
- Remove some unused ssl procs
- 63-bit time_t support in TS deltas
- const char * vs char * cleanup
- struct alignment (void *) casts
- signed vs unsigned fixes
- bad memset() call
- Bad LT_MAIN in libratbox
- char -> unsigned char casts for isdigit/isspace/etc calls

Thanks Jilles!
