Frederic Weisbecker added a bunch of changes to the perf code. This
is a port of his work to trace-cmd.

All traces have info about interrupts disabled, preempt count
and needing rescheduling. Add an option to expose these.

The ftrace bprint uses a special binary format to record trace_print
events. This patch changes trace-cmd to handle the format. Part of
that is to read (and record) the printk_formats file in the trace.dat.

Parse out the header_page from the tracing/events directory to
get the page header offsets and sizes. We can also use the "commit"
field to get the long size of the kernel, incase the kernel
and the userspace have different word sizes.

Archs may use different page sizes. We must use the target arch page
size for this instead of just hard coding 4096. This must also be saved
in the data file so that it can be read by the host data.
Also fixed the bigendian routine on the recording side.

When testing a data file created on x86 on a PPC box, I found that
there was a missing conversion of reading the values. This patch
moves the data2host to the header file and converts the necessary
fields.
