The libtool current:revision:age numbers change from 3:0:0 to 3:1:0.

This changes the library filename (e.g. on Linux) from
libsigrokdecode.so.3.0.0 to libsigrokdecode.so.3.0.1, the SONAME
(+symlink) stays at libsigrokdecode.so.3, though.
# The algorithm for determining which number to change (and how) is nontrivial!
