1) Add flexible seeking support (including absolute) for memory block queues and playback streams

2) Add support to synchronize multiple playback streams
3) add two tests for 1) and 2)
4) s/PA_ERROR/PA_ERR/
5) s/PA_ERROR_OK/PA_OK/
6) update simple API to deal properly with new peek/drop recording API
7) add beginnings of proper validity checking on API calls in client libs (needs to be extended)
8) report playback buffer overflows/underflows to the client
9) move client side recording mcalign stuff into the memblockq 
10) create typedefs for a bunch of API callback prototypes
11) simplify handling of HUP poll() events

Yes, i know, it's usually better to commit a lot of small patches instead of a
single big one. In this case however, this would have contradicted the other
rule: never commit broken or incomplete stuff.

*** This stuff needs a lot of additional testing! ***
