Add trace support to 16B bypass packets during send and
receive.
Sample input header trace:

Calls to trace incoming packets will now receive the packet
context as parameter. This enables trace support for future
packet types.
Header trace output is in the format <field>:<value>
which makes parsing easier.

Use common header file structs, defines, and accessors
in the drivers. The old declarations are removed.
The repositioning of the includes allows for the removal
of hfi1_message_header and replaces its use with ib_header.
Also corrected are two issues with set_armed_to_active():
- The "packet" parameter is now a pointer as it should have been
- The etype is validated to insure that the header is correct

The ftrace infrastructure used to evaluate the TRACE_SYSTEM
macro on every DEFINE_EVENT() macro. Now the TRACE_SYSTEM
macro only gets evaluated when trace/define_trace.h is
included, so the group event information is lost. This was
introduced in
commit acd388fd3af3 ("tracing: Give system name a pointer")
Therefore, each system tracepoint must be on its own file.
