revent: Various fixes.

revent:
    - Fixed 32-bit/64-bit compatibility by no longer "long" for timestamps
    - Removed superfluous code
    - SIGTERM is now handled only while waiting for a file not while processing one
    - Added '-s' to docs
    - Fixed path_buff size

Record Command:

    - Removed timeout in command as -s is specified.
    - Previously the command would send SIGTERM to revent but not wait for it to terminate.
      This would result in the pulled recording missing its send. This has now been fixed.

Replay Command:
    - Added more logging
