perf list: Move extra details printing to new option (2017-03-23 11:42:31 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

User visible:

- Allow suppressing 'uncore_' when specifying PMU events (Andi Kleen)

- Collapse identically named PMU events in 'perf stat', allow
not merging it via --no-merge (Andi Kleen)

Fixes:

- Use more precise 'grep -v' to suppress unwanted 'objdump -dS'
disassembly output to not ditch line:number lines needed by
'perf annotate --print-lines' logic (Taeung Song)

Infrastructure:

- SDT (Statically Defined Tracing)/uprobes_events arguments improvements
(Alexis Berlemont, Ravi Bangoria)

- Improvements for the handling of JSON described vendor events,
including having an expression parser to calculate metrics
from multiple vendor events (Andi Kleen)

- Update Intel JSON vendor event files (Andi Kleen)

- Restore error reporting in 'perf probe -d' when none of the events
requested to be deleted exist. (Kefeng Wang)

- Bump MAX_CMDLEN in 'perf probe' to match what the kernel accepts
(Ravi Bangoria)

Test results:

The first ones are container (docker) based builds of tools/perf with and
without libelf support, objtool where it is supported and samples/bpf/, ditto.
Where clang is available, it is also used to build perf with/without libelf.

Several are cross builds, the ones with -x-ARCH, and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
