checkpatch: make -f alias --file, add --help, more verbose help message
Impact:
- More verbose help/usage message.
- Make the option -f an alias for --file.
- On -h, --help, and --version display help message and exit(0).
- With no FILE(s) given, exit(1) with "no input files".
- On invalid options display help/usage and exit(1).
Based on a patch by Pavel Machek.
