Move Linux CI from Travis to Sourcehut

Ensure ratio marked unset again on reset

Add -lsamplerate

Don't invite smoothing when setting the very first ratio

Slightly clearer error reporting

Fixes for libsamplerate and ipp, brought back from rb code

Bump these standards up a bit. Machines are a bit faster, and none of the other resamplers ever had a configuration quite as bad as the linear one.

The initialSampleRate is just a guide, but implementations may fail if it's not given - make it default

Prefer libsamplerate at any performance setting, now we know it is better-behaved on rate changes

Add references to other bqlibs

Employ a newer Linux platform to avoid spurious valgrind warnings

Bitbucket -> Sourcehut

Delegate between resampling functions for SRC case, to slightly simplify code

Remove some unused fields

Update before install; seems to be necessary (based on other projects) to avoid recent Ruby-related error

Fill out reset (thanks JF)

Include overriding Makefile.inc-bq if present

Very tiny tidy
