perf trace: Support 'strace' syscall event groups
I.e.:
$ cat ~/share/perf-core/strace/groups/file
access
chmod
creat
execve
faccessat
getcwd
lstat
mkdir
open
openat
quotactl
readlink
rename
rmdir
stat
statfs
symlink
unlink
$
Then, on a quiet desktop, try running this and then moving your mouse to
see the deluge of mouse related activity:
# perf probe 'vfs_getname=getname_flags:72 pathname=filename:string'
Added new event:
probe:vfs_getname (on getname_flags:72 with pathname=filename:string)
You can now use it in all perf tools, such as:
perf record -e probe:vfs_getname -aR sleep 1
#
# trace --ev probe:vfs_getname --filter-pids 2232 -e file
0.042 (0.042 ms): mousetweaks/2235 open(filename: 0x14e3910, mode: 438 ) ...

0.468 (0.017 ms): mousetweaks/2235 ... [continued]: open()) = -1 ENOENT No such file or directory
Need to combine that raw_syscalls:sys_enter(open) + probe:vfs_getname +
raw_syscalls:sys_exit(open) sequence...
Now, if you're bored, please write some more syscall groups, like the ones
in 'strace' and send it our way :-)

perf test: Add libbpf relocation checker
There's a bug in LLVM that it can generate unneeded relocation
information. See [1] and [2]. Libbpf should check the target section of
a relocation symbol.
This patch adds a testcase which references a global variable (BPF
doesn't support global variables). Before fixing libbpf, the new test
case can be loaded into kernel, the global variable acts like the first
map. It is incorrect.
Result:
# ~/perf test BPF
37: Test BPF filter :
37.1: Test basic BPF filtering : Ok
37.2: Test BPF prologue generation : Ok
37.3: Test BPF relocation checker : FAILED!
# ~/perf test -v BPF
