2358fabb70 Optimization to latest aac decoder changes. Significantly reduce loop count in m4a_check_sample_offset() during standard playback. Before this change the loop count increased with each decoded chunk and for each frame.

68199cc195 Major rework of the m4a parser for aac/alac playback, seek and resume support. As a result the memory consumption was drastically reduced. This allows to play several files with long duration -- especially on low memory targets. The change builds a lookup table from m4a's sample_to_chunk[] and chunk_offset[] and completely removes the allocation of the large tables chunk_offset[] and sample_byte_size[]. To be able to remove reading and allocating sample_byte_offset[] the aac and alac decoder now buffer a fixed amount of bytes for each frame. The generated lookup table is used for seek/resume and skipping bytes in empty chunks (aac decoder only). The precision for seek/resume is somewhat lower but still equals 0.5 sec for the worst case. Fixes FS#8923.

35e8b1429a Rockbox as an application: Replace many occurences of #ifdef SIMULATOR with #if (CONFIG_PLATFORM & PLATFORM_HOSTED) (or equivalently). 
The simulator defines PLATFORM_HOSTED, as RaaA will do (RaaA will not define SIMULATOR).
The new define is to (de-)select code to compile on hosted platforms generally.

Should be no functional change to targets or the simulator.

008c368c87 Commit first part of FS#10832 by Juliusz Chroboczek. Allows playback of unstreamable AAC/ALAC files by stepping through the file to find the index, potientially rebuffering. This is likely to impose a battery life hit on files which are unstreamable and not much smaller then the buffer, but should not impact streamable files at all.

2e6d604bb6 Stop hiding errors by redirecting stderr to /dev/null. If we really need to do re-introduce somewhere we should rather make it dependent on the V variable so that make V=1 would still show the error and only "normal" builds would hide it.

aaacb7010f Remove the mallocs for the codecdata in the m4a parser and assume a maximum size of 64 bytes (see comments in source). Also clean up the alac_set_info() function a little and make it alignment-safe. We still need to remove the seektable related mallocs. Please report if any AAC or ALAC files stop playing in Rockbox after this commit - but it is not expected to cause problems.
