  1. context: Constify 'iio_backends' array 

    This array contains data known at compile-time and is never updated
later; so it can be const.

  2. dynamic: Remove duplicated error message 

    We only need to print it once; and it makes more sense to print it at
the "debug" log level.

  3. iio: Rework API functions to get backends 

    They previously would only work with the backends provided by Libiio,
either built-in or modules, enabled at compilation time.

This meant that third-party modules were not listed in there, while
official modules were.

Change these functions so that they only work for built-in backends, and
rename them to iio_get_builtin_backends_count() and
iio_get_builtin_backend().

  4. iio: Support dynamic backends in iio_has_backend() 

    If the backend name cannot be found in the list of built-in backends,
check if a module exists for it.

Since the loading of a dynamic backend might print errors (e.g. if the
file is unrecognized), the iio_has_backend() function now accepts an
extra "params" argument.

  5. compat: Update to new backend functions 

    Update to the new prototype of iio_has_backend(), and use the new

iio_get_builtin_backend().
