Second batch of perf tooling fixes for v5.8:
- Intel PT fixes for PEBS-via-PT with registers.
- Fixes for Intel PT python based GUI.
- Avoid duplicated sideband events with Intel PT in system wide tracing.
- Remove needless 'dummy' event from TUI menu, used when synthesizing
meta data events for pre-existing processes.
- Fix corner case segfault when pressing enter in a screen without
entries in the TUI for report/top.
- Fixes for time stamp handling in libtraceevent.
- Explicitly set utf-8 encoding in perf flamegraph.
- Update arch/x86/lib/memcpy_64.S copy used in 'perf bench mem memcpy',
silencing perf build warning.

Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
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.
Some of the most recent, experimental distros are failing, fixes will be
provided, but those gcc/clang versions are not yet in general use and some
are related to linking with libllvm, not the default build.
