Loading the config file after processing command line options can cause problems, e.g. where an engine provides new ciphers/digests these are not then recoginised on the command line. Move the default config file loading to before the command line option processing. Whilst we're doing this we might as well centralise this instead of doing it individually for each application. Finally if we do it before the OpenSSL_add_ssl_algorithms() call then ciphersuites provided by an engine (e.g. GOST) can be available to the apps.
