3fb013065f Implement get_chmap/set_chmap for PCM plug, route and multi plugins
Still incomplete implementations.  The query and set ops are missing
for route and multi plugins.

03388ca6d3 Mark static tables as constant when possible.
This makes it possible to write them to .data.rel.ro or to .rodata if
there is no relocation involved (arrays of character arrays).

8b14625cc3 Make all the PCM plugins ops structure constant.
This ensures they are emitted in .data.rel.ro rather than .data.rel,
which should make a nice difference when using prelink.

4433248bf3 remove superfluous free() checks
free() correctly handles NULL pointers, so we can omit explicit checks
for that condition.

02e9d7c3e6 - fixed the routing with use_getput condition.
use_getput will be changed after loading the ttable, so the conversion
  function cannot be determined at this stage.
