Ftrace supports uprobes - trace events on user space applications.
Trace-cmd cannot configure uprobes, in order to support it this new
functionality is introduced:
- Function name to file offset mapping, this information is extracted
from the dwarf and ELF headers in the binary file.
- New options are added to "trace-cmd record" for setting a uprobe:
--uprobe file:function
--uprobe-ret file:function
