2b54677fdb Change error message handling 
Change the handling of non-fatal errors.  Now the non-fatal error
messages are not shown in stderr and no assert() as default.  The
behavior can be changed with LIBASOUND_DEBUG environment variable.

6987a8555c appl_ptr sync fix when status/control structures are not mmaped

must take modified appl_ptr from driver.
