btrace: add struct btrace_data

Add a structure to hold the branch trace data and an enum to describe
the format of that data.  So far, only BTS is supported.  Also added
a NONE format to indicate that no branch trace data is available.

This will make it easier to support different branch trace formats in
the future.
