Subject: cmdutils: add print_program_info() used in both show_banner() and show_version()
X-Git-Url: https://git.sesse.net/?a=commitdiff_plain;h=9ac58ba1332d882964649c69686091e04f27dd26;p=ffmpeg

This also make -version show program configuration and compilation
information, which was previously shown only in the banner.
