Remove unused IPC::Message priority.

Removes the PriorityValue enum and field from IPC::Message. This doesn't
appear to be used anywhere.

Changes the data message ctor to take a size_t data_len parameter.  This
works around an ambiguity problem with the main ctor, which has a similar
signature and would require lots of futzing with our test code to fix. To
make this work, the matching Pickle constructor is also changed to take a
size_t data_len parameter.
