In the case of division by zero in a BPF program:

the expected behavior is to terminate with return value 0.

According to [1], 'perf state' should avoid output too much information
if '-v' not set, only 'Ok', 'FAIL' or 'Skip' need to be printed.
This patch removes sereval stderr output to make output clean.
Before this patch:
# perf test dummy
23: Test using a dummy software event to keep tracking
A series of bpf loader related error code is introduced to help error
delivering. Functions are improved to return those new error code.
Functions which return pointers are adjusted to encode error code into
return value using "ERR_PTR".
bpf_loader_strerror() are introduced to convert those error
In this patch, a series libbpf specific error numbers and
libbpf_strerror() are created to help reporting error to caller.
Functions are updated to pass correct error number through macro
CHECK_ERR().
All users of bpf_object__open{_buffer}() and bpf_program__title()
in perf are modified accordingl
According to [1], libbpf should be muted. This patch reset info and
warning message level to ensure libbpf doesn't output anything even
if error happened.

This patchset is based on perf/core
(commit bebd23a2ed31d47e7dd746d3b125068aa2c42d85 in Arnaldo's tree).
Compare with v1 [1], this patchset changes error reporting convention
and the user of it at one same patch, avoid NULL checking in perf.

Side note, I have an *old* patch that I think simplifies the
(reasonably common) case of sending IPI's to individual CPU's. That's
done by the "reschedule ipi" in particular.
