add const where applicable, drop const where unnecessary
This patch adds the const qualifier to a number of function arguments
(mostly string arguments) so that client libraries can pass their own
const strings to the library without having to cast their const'ness
away.
This also drops a couple of consts where call-by-value is done anyway,
and which hence has no effect and just misleads the users and adds
unnecessary noise to the signal. After all this is C, not C++.
