perf/core improvements and fixes: 

User visible:
 
 - Allow selecting the type of callchains per event, including disabling
   callchains in all but one entry in an event list, to save space, and also
   to ask for the callchains collected in one event to be used in other
   events (Kan Liang)
 
 - Beautify more syscall arguments in 'perf trace': (Arnaldo Carvalho de Melo)
   - A bunch more translate file/pathnames from pointers to strings
   - Convert numbers to strings for the 'keyctl' syscall 'option' arg.
   - Add missing 'clockid' entries
 
 - Fix 'perf probe -L sys_*' as it was not showing all the source code for
   syscall functions in the kernel (Masami Hiramatsu)
 
 - Make ESC unzoom as well in the hists browser, i.e. in 'report' and 'top',
   as we're considering repurposing the right and left arrow keys to use in
   horizontal scrolling, i.e. leave just ESC to be used for what <- works
   now, and ENTER for what -> does (they are already aliases for ages)
   (Arnaldo Carvalho de Melo)
 
 Infrastructure fixes:
 
 - Check for SRCLINE_UNKNOWN case in "srcfile" processing (Andi Kleen)
 
 - Wrap the slsmg_{printf,write_nstring} slang functions behing ui_browser, so
   that we can make the ui_browser based browsers (annotate, menus, hists, etc) UI
   library agnostic and usable with multiple backends (slang now, GTK+ and others
   in the future, maybe) (Arnaldo Carvalho de Melo)

FP mode, "dwarf" for DWARF mode, "lbr" for LBR mode and

--full-source-path::
Show the full path for source files for srcline output.
--show-ref-call-graph::
When multiple events are sampled, it may not be needed to collect
callgraphs for all of them. The sample sites are usually nearby,
and it's enough to collect the callgraphs on a reference event.
So user can use "call-graph=no" event modifier to disable callgraph
for other events to reduce the overhead.
However, perf report cannot show callgraphs for the event which
disable the callgraph.
This option extends the perf report to show reference callgraphs,
which collected by reference event, in no callgraph event.
