0f5f5bcd11 perf script: Add callchain to generic and tracepoint events 
This provides valuable information for tracing performance problems.

Since this change alters the interface for the python scripts, also
adjust the script generation and the provided scripts.

765532c8aa perf script: Finish the rename from trace to script 
The scripts have calls to 'perf trace' that need to be converted to 'perf script', do it.

This problem was introduced in 133dc4c.

c02514850d perf scripts python: Give field dict to unhandled callback 
trace_unhandled() callback does not allow to access event fields, this patch
resolves the problem.

It can also been used as a more pythonic and flexible way for script writters
to demux event types

This will for example greatly simplify pytimechart event demux.

4d161f0360 perf/scripts: Add syscall tracing scripts 
Adds a set of scripts that aggregate system call totals and system
call errors.  Most are Python scripts that also test basic
functionality of the new Python engine, but there's also one Perl
script added for comparison and for reference in some new
Documentation contained in a later patch.
