[PATCH 09/11] tools lib traceevent: Add alias field to struct format_field

From: Jiri Olsa
Date: Fri Feb 20 2015 - 17:19:15 EST

Introduce an alias field to 'struct format_field' to be able
to use alternative name for the field.

This will be handy when converting data into CTF, where each
field within event needs to have a unique name (while this
is not required for tracepoint). Converter can easily assign
unique name into the format_field struct.
