perf/core improvements and fixes:

Intel PT:
 
   Adrian Hunter:
 
   - Add PEBS via Intel PT support, the kernel bits went via PeterZ.
 
 perf record:
 
   Alexander Shishkin:
 
   - Add an option to take an AUX snapshot on exit.
 
   Tan Xiaojun:
 
   - Support aarch64 random socket_id assignment, just like was fixed for S/390.
 
 tools:
 
   Andy Shevchenko:
 
   - Keep list of tools in alphabetical order on 'make -C tools help'.
 
 perf session:
 
   Arnaldo Carvalho de Melo:
 
   - Avoid infinite loop when seeing invalid header.size, reported by
     Vince Weaver using a perf.data fuzzer.
 
 Documentation:
 
   Vince Weaver:
 
   - Clarify HEADER_SAMPLE_TOPOLOGY format in the perf.data spec.
 
 perf config:
 
   Arnaldo Carvalho de Melo:
 
   - Honour $PERF_CONFIG env var to specify alternate .perfconfig.
 
 perf test:
 
   Arnaldo Carvalho de Melo:
 
   - Disable ~/.perfconfig to get default output in 'perf trace' tests.
 
 perf top:
 
   Arnaldo Carvalho de Melo:
 
   - Set display thread COMM to help with debugging.
 
   - Collapse and resort evsels in a group, so that we have output
     similar to 'perf report' when using event groups, i.e.
 
       perf top -e '{cycles,instructions}'
 
     Will have two columns, and the instructions one will work.
 
 core:
 
   Igor Lubashev:
 
   - Detect if libcap development files are available so that we
     can use capabilities to match the checks made by the kernel instead
     of using plain (geteuid() == 0).
 
 Intel:
 
   Haiyan Song:
 
   - Add Icelake V1.00 event file.
 
 perf trace:
 
   Leo Yan:
 
   - Fix segmentation fault when access syscall info on arm64.
