Reentrant version of decompress routine in CFE FS

[skliper]

The FS application has a feature where it can decompress file content on the fly. However the decompression routine keeps its internal state in global variables which makes it non-reentrant. To protect against concurrent usage a mutex is used but this has a major performance impact.

The global variables should be replaced with a state structure so that it can be multithreaded like all other parts of CFS.

For the time being a global state object can be implemented in order to preserve API compatibility.
