dd464345f3 perf diff: Refactor diff displacement possition info
Moving the position calculation into the diff command, so the position
as prepared inside struct hist_entry data and there's no need to compute
in the output display path.

Removing 'displacement' from struct perf_hpp as it is no longer needed.

ae359f193a perf hists: Add struct hists pointer to struct hist_entry
Adding pointer back to the parent struct hists for struct hists_entry.

This will be useful in future for any hist_entry's data computation,
that depends on total data of its parent hists.

ae0c1f9934 perf tools: Complete tracepoint event names
Currently tracepoint events cannot be completed because they contain a
colon (:) character.  The colon is considered as a word separator when
bash completion is done - variable COMP_WORDBREAKS contains colon - so
if a word being completed contains a colon it can be a problem.

Recent versions of bash completion provide -n switch to
_get_comp_words_by_ref and __ltrim_colon_completions functions in order
to resolve this issue.  Copy the latter in case not exists.

4e34d9588b perf tools: Convert to BACKTRACE_SUPPORT
For building perf without stack backtrace debug, we can set
NO_BACKTRACE=1 as a argument of make.  It then defines NO_BACKTRACE
macro for C code to do the proper handling.  However it usually used in
a negative semantics - e.g. #ifndef - so we saw double negations which
can be misleading.  Convert it to a positive form to make it more
readable and add _SUPPORT suffix for consistency.

5ded57ac1b perf inject: Remove static variables
We want to reduce the impact that each of the builtins has on perf as a
whole, so use the superclassing of perf_tool mechanizm to move its
config knobs to the stack, so that only if we use that tool, its impact

In this case is more about consistency, as the impact of this tool is
minimal.

For building perf without libnewt, we can set NO_NEWT=1 as a argument of
make.  It then defines NO_NEWT_SUPPORT macro for C code to do the proper
handling.  However it usually used in a negative semantics - e.g.  #ifndef -
so we saw double negations which can be misleading.  Convert it to a
positive form to make it more readable.

514f1c67c2 perf trace: New tool
Initially should look loosely like the venerable 'strace' tool, but
using the infrastructure in the perf tools to allow tracing extra
targets:

  [acme@sandy linux]$ perf trace --hell
  Error: unknown option `hell'

   usage: perf trace <PID>

      -p, --pid <pid>       trace events on existing process id
          --tid <tid>       trace events on existing thread id
          --all-cpus        system-wide collection from all CPUs
          --cpu <cpu>       list of cpus to monitor
          --no-inherit      child tasks do not inherit counters
          --mmap-pages <n>  number of mmap data pages
          --uid <user>      user to profile

  [acme@sandy linux]$

Those should have the same semantics as when using with 'perf record'.

It gets stuck sometimes, but hey, it works sometimes too!

In time it should support perf.data based workloads, i.e. it should have
a:
	-o filename

Command line option that will produce a perf.data file that can then be
used with 'perf trace' or any of the other perf tools (script, report,
etc).

It will also eventually have the set of functionalities described in the
previous 'trace' prototype by Thomas Gleixner:

   "Announcing a new utility: 'trace'"
   http://lwn.net/Articles/415728/

Also planned is to have some of the features suggested in the comments
of that LWN article.

eb2f270338 perf test: Add test to check we correctly parse and match syscall open parms
It will set up a syscall open tracepoint event, generate an open with
invalid flags, then check those flags were the ones reported in the
tracepoint fired.

For the filename we need vfs:getname, but that will go thru some more
iterations as the vfs getname codebase is going thru changes lately.

When that is in I'll just check that the perf_evsel__newtp constructor
is not bailing out and then add it to the evlist, catch the event and
check the filename against the one used in the 'open' call used to
trigger the event.

e6b6f67952 perf evsel: Handle endianity in intval method
We were relying on the info in pevent, but since we have it in
perf_evsel, set up by the perf_session routine if read from a perf.data
file or by whoever creates the evsels, use it.

New 'perf test' entries will use it to parse locally generated events,
in a non perf.data centered workflow.

As well as use byteswap.h to get per arch optimized swap routines, like
other parts of perf (header, perf_evsel__parse_sample, symbol, etc)
already do.
