Return errno when open_memstream() fails and add two new speciall error
codes for when an invalid, non BPF file or one without BTF is passed to
symbol__disassemble_bpf(), so that its callers can rely on
symbol__strerror_disassemble() to convert that to a human readable error
message that can help figure out what is wrong, with hints even.

We were just returning -1 in symbol__annotate() when symbol__annotate()
failed, propagate its error as it is used later to pass to
symbol__strerror_disassemble() to present a error message to the user,
that in some cases were getting:
"Invalid -1 error code"
Fix it to propagate the error.

propagate error values from functions it calls, starting with

'errno' to see why its possible call to uname() failed.

When the LBR data and the instructions in a binary do not match the loop
printing instructions could get confused and print a long stream of
bogus <bad> instructions.
The problem was that if the instruction decoder cannot decode an
instruction it ilen wasn't initialized, so the loop going through the
basic block would continue with the previous value.
Harden the code to avoid such problems:
- Make sure ilen is always freshly initialized and is 0 for bad
instructions.
- Do not overrun the code buffer while printing instructions
- Print a warning message if the final jump is not on an instruction
boundary.

with an incorrect filename. Specifically it was missing the ".so" suffix.
Further the JIT_CODE_LOAD record were silently truncating the

Whenever an mmap/mmap2 event occurs, the map tree must be updated to add a new
entry. If a new map overlaps a previous map, the overlapped section of the
previous map is effectively unmapped, but the non-overlapping sections are
still valid.
maps__fixup_overlappings() is responsible for creating any new map entries from
the previously overlapped map. It optionally creates a before and an after map.
When creating the after map the existing code failed to adjust the map.pgoff.
This meant the new after map would incorrectly calculate the file offset
for the ip. This results in incorrect symbol name resolution for any ip in the
after region.
Make maps__fixup_overlappings() correctly populate map.pgoff.
Add an assert that new mapping matches old mapping at the beginning of
the after map.

it will override the default date written to the man page metadata.
Without this change, or if the perf_date isn't specified, then the

Having this parameter allows the metadata to be constant if builds
happen on different dates.
The name of the parameter is intended to be consistent with the existing

I'm not fully sure if this is the correct fix, but without this I get
crashes on more complex perf stat metric usages. The problem is that
part of the state gets freed when a weak group fails, but then is later
still used. Just don't free the ids, we're going to reuse them anyways
on the weak group retry.
For example:
% perf stat -M IpB,IpCall,IpTB,IPC,Retiring_SMT,Frontend_Bound_SMT,Kernel_Utilization,CPU_Utilization --metric-only -a -I 1000 sleep 2
crashes and gives in valgrind:

Make sure to not free the name passed in by the caller, but free all the
allocated ids when parsing expressions.
The loop at the end knows that the first entry shouldn't be freed, so
make sure the caller name is the first entry.

Ditch it, noone is using it, one more stdio.h include in a hot header.
Fix the fallout in parse-events.y, where we end up using a FILE pointer,
I think due to YYDEBUG being set and in some places, like Amazon Linux 1
we don't get stdio.h included by luck, like in most other places, add a
explicit stdio.h include directive.

it should be there because of some needed typedef, and it is much

Move 'sample_id' array from 'struct evsel' to libperf's 'struct perf_evsel'.
Committer notes:
Removed the 'struct xyarray' from util/evsel.h, not needed anymore
