Subject: [PATCH] Add util/openssl-update-copyright shell script

usage: openssl-update-copyright [-h|--help] [file|directory] ...

Updates the year ranges of all OpenSSL copyright statements in the given
files or directories. (Directories are traversed recursively.)

Only copyright statements containing the string 'The OpenSSL Project' are
affected. The copyright time range is adjusted to include the current year.
If only a single year was specified, it is replaced by a time range starting
at that year and ending at the current year. All '(c)' and '(C)' signs are
preserved.
