The SPU decrementer should be restored after the LSCSA DMA has
completed.

1cfc0f86eb [CELL] spufs: fix decr_status meanings
The decr_status in the LSCSA is confusedly used as two meanings:
 * SPU decrementer was running
 * SPU decrementer was wrapped as a result of adjust
and the code to set decr_status is missing.

This patch fixes these problems by using the decr_status argument as a
set of flags. This requires a rebuild of the shipped spu_restore code.

05b841174c [PATCH] spufs: add spu-side context switch code
Add the source code that is used to generate spu_save_dump.h and
spu_restore_dump.h. Since a full spu tool chain is needed to
generate these files, the default remains to use the shipped
versions in order to keep the number of tools for building the
kernel down.
