tracedump: Dump ftrace ring buffer data

Add a new module that will dump the contents of the ftrace ring buffer.
Data is compressed and can be in ascii or binary form. Data will
automatically dump on kernel panic to console. Data can be dumped by
reading /proc/tracedump. See tracedump.h for details.
