perf tools changes for v5.9: 2nd batch

Fixes:
 
 - Fixes for 'perf bench numa'.
 
 - Always memset source before memcpy in 'perf bench mem'.
 
 - Quote CC and CXX for their arguments to fix build in environments using
   those variables to pass more than just the compiler names.
 
 - Fix module symbol processing, addressing regression detected via "perf test".
 
 - Allow multiple probes in record+script_probe_vfs_getname.sh 'perf test' entry.
 
 Improvements:
 
 - Add script to autogenerate socket family name id->string table from copy of
   kernel header, used so far in 'perf trace'.
 
 - 'perf ftrace' improvements to provide similar options for this utility so
   that one can go from 'perf record', 'perf trace', etc to 'perf ftrace' just
   by changing the name of the subcommand.
 
 - Prefer new "sched:sched_waking" trace event when it exists in 'perf sched'
   post processing.
 
 - Update POWER9 metrics to utilize other metrics.
 
 - Fall back to querying debuginfod if debuginfo not found locally.
 
 Miscellaneous:
 
 - Sync various kvm headers with kernel sources.

 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.
 
 fedora:rawhide with python3 and gcc 10.1.1-2 is failing (10.1.1-1 on fedora:32
 works), fixes will be provided soon.
 
 clearlinux:latest is failing on libbpf, there is a fix already in the bpf tree.

Merge tag 'perf-tools-2020-08-14' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull more perf tools updates from Arnaldo Carvalho de Melo:
 "Fixes:
   - Fixes for 'perf bench numa'.

   - Always memset source before memcpy in 'perf bench mem'.

   - Quote CC and CXX for their arguments to fix build in environments
     using those variables to pass more than just the compiler names.

   - Fix module symbol processing, addressing regression detected via
     "perf test".

   - Allow multiple probes in record+script_probe_vfs_getname.sh 'perf
     test' entry.

  Improvements:
   - Add script to autogenerate socket family name id->string table from
     copy of kernel header, used so far in 'perf trace'.

   - 'perf ftrace' improvements to provide similar options for this
     utility so that one can go from 'perf record', 'perf trace', etc to
     'perf ftrace' just by changing the name of the subcommand.

   - Prefer new "sched:sched_waking" trace event when it exists in 'perf
     sched' post processing.

   - Update POWER9 metrics to utilize other metrics.

   - Fall back to querying debuginfod if debuginfo not found locally.

  Miscellaneous:
   - Sync various kvm headers with kernel sources"
