* Generate the compressionHelper functions and fix compression.
This was a long standing TODO: generate the compression helper
functions. This now automatically picks up new names that can be
used for compression.
When packing add names to compression map:
When packing a message we should only compress when compress is true.
But whenever the compression map is not nil we should still add names
to it that can be *used* for future compression. The packing
inadvertently only added those names when compress would be true.
* Removed unused functions
