This patch is to remove following hardware events
from JSON file which are not supported on POWER8.

pm_l3_p0_grp_pump
pm_l3_p0_lco_data
pm_l3_p0_lco_no_data
pm_l3_p0_lco_rty

  Note: Unfortunately power8 event list is not publicly available.

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.

reduce evsel.h a bit more.

We needed a new perf_event_attr_fprintf.c file so as to have a separate

The sys/types.h header looks more sensible, from its name we can gather
it should be there because of some needed typedef, and it is much
smaller than unistd.h, so use it and fix up the fallout in places where
it was being used for something else entirely but being obtained by
sheer luck, indirectly.

That was done just to have users of writen() and readn(), that before
had their prototypes in util/util.h to get it without having to add an
include for internal/lib.h, but the right way is to add it and by now
all places already do it.

Fix a fallout were readlink() was used but unistd.h was being obtained
by luck thru util.h -> internal/lib.h, now to check why unistd.h is
being included there...
