sysparam: rework.

Browse source 
Adds a semaphore used by readers are writers.

Fixes writing to the flash from constant data stored in the flash, using a bounce buffer.

Handle reading into unaligned value buffers.

Removed memory allocation from most read and write paths. Only read paths that return a blob of data allocate memory now, and the iterator.

Store small integers as binary values, avoiding parsing and formatting in these paths.
