...
Fixing the dynamic array format field parsing.
Currently the event_read_fields function could segfault while parsing
dynamic array other than string type. The reason is the event->pevent
does not need to be set and gets dereferenced unconditionaly.
Also adding proper initialization of field->elementsize based on the
parsed dynamic type.

Sometimes a test is problematic for some reason and one wants to skip it,
for instance:

3: detect open syscall event on all cpus : Ok
4: read samples using the mmap interface : Ok

Warning: bad op token {
Warning: bad op token {
Warning: bad op token {
Warning: bad op token {
Warning: function is_writable_pte not defined
Segmentation fault (core dumped)
So now we can use -s/--skip while the problematic tests are being fixed,
allowing us to test all the other entries:
[root@sandy ~]# perf test -s 5
1: vmlinux symtab matches kallsyms : Ok
2: detect open syscall event : Ok
3: detect open syscall event on all cpus : Ok
4: read samples using the mmap interface : Ok
5: parse events tests : Skip (user override)
6: x86 rdpmc test : Ok
7: Validate PERF_RECORD_* events & perf_sample fields : Ok
8: Test perf pmu format parsing : Ok
9: Test dso data interface : Ok
10: roundtrip evsel->name check : Ok
11: Check parsing of sched tracepoints fields : Ok
12: Generate and check syscalls:sys_enter_open event fields: Ok
13: struct perf_event_attr setup : Ok

perf script: hook up perf_scripting_context->pevent
...
Running the check-perf-trace scripts causes segfaults in both the Perl
and Python cases:
# perf script record check-perf-trace
# perf script -s libexec/perf-core/scripts/python/check-perf-trace.py
trace_begin
Segmentation fault (core dumped)
The reason is that the 'pevent' field was added to
perf_scripting_context but it wasn't hooked up with an actual pevent in
either case, so when one of the 'common' fields is accessed (in
util/trace-event-parse.c:get_common_fields()), pevent->events tries to
dereference a NULL pointer.
This sets the pevent field when the scripting context is set up.

perf tools: Reinstate 'signed' field flag for tracepoints
...
For some reason the libtraceevent tracepoint-parsing code is missing
the FIELD_IS_SIGNED flag-setting code, which causes problems for the
Perl trace event binding at least, since it ends up unable to
recognize negative numbers.
Things like checking for negative return values therefore fail, causing
scripts like rwtop to instead interpret the negative return value as a
large positive value, which in turn get added to e.g. read totals with
insanely invalid results.
So set the FIELD_IS_SIGNED flag for tracepoint events that specify
"signed:1".
