zita-convolver-4.0.3-bp153.1.19

- Update to version 4.0.3 (no changelog)

- Add baselibs.conf
- Update to version 4.0.0
  1. Version 4 now uses int types from <stdint.h> internally and for
    the arguments of all member funcions.
  2. The set_density() function has been removed, and the matrix
    density hint is now an additional argument to configure().
  If your application does not use impdata_update(), then (1)
  and (2) are the only relevant changes.
  3. The way impdata_update() works has changed.
    This function is used to modify IR data while the convolver is
    actually running. It does not use any memory allocation nor
    modify internal data structures, and only data in already
    existing partitions can be modified this way.
    In versions <= 3, this function would *overwrite* any existing
    data. From version 4, impdata_update() *adds* to existing IR
    data, just as impdata_create() does. So in order to replace an
    existing IR, you first need to clear it using the new function
    impdata_clear(). This will clear (but not delete) all IR data
    for a given input, output pair.

- Replace %soname by %sover to better reflect its use.
- Drop bias from description.
- Add Group: line for shared library subpackage.

- init, 3.1.0
