Subject: [PATCH] scripts/api-version-bump.sh: Adjust hard-coded API version

This script is called from the package's top directory to adjust
all places where the current API version is hard-coded. The
current version is detected from the LIBCOAP_API_VERSION in
configure.ac. The target version is LIBCOAP_API_VERSION + 1 if no
parameter is provided on the command line. Otherwise, the given
value is used as target version.

Note that calling this script also results in 'git mv' operations.
git commit must be called manually after running this script.
