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...

As this isn't used at all in mmap.h but in evlist.h, so to cut down the
header dependency tree, move it to where it is used.
Also add mmap.h to the places using it but previously getting it
indirectly via evlist.h.
Add missing pthread.h to evlist.h, as it has a pthread_t struct member
and was getting the header via mmap.h.
Noticed while processing a Jiri's libperf batch touching mmap.h, where
almost everything gets rebuilt because evlist.h is so popular, so cut
down't this rebuild the world party.

The tep_get_event() function is an official libtracevent API, described
in the library man pages. However, it cannot be used by the library users because
it is not declared in the event-parse.h file, where all libtracevent APIs are.
The function declaration is added in event-parse.h file.

APIs for printing various trace event information were redesigned to be
more simple. However, the main libtraceevent man page was not updated
with those changes. The documentation is updated to describe the new
event print API.

The tep_ref_get() was renamed to tep_get_ref(), to be more consistent
with the other tep_ref_* APIs. However, in the man pages the API is
still with the old name. The documentation is fixed to reflect the
actual name of the API.

When testing the output of the old trace-cmd compared to the one that
uses the updated tep_print_event() logic, it was different in that the
time stamp precision in the old format would round up to the nearest
precision, where as the new logic truncates. Bring back the old method
of rounding up.

Enhance usability by allowing the same plurality used in the output
title, for the command line parameter.
BEFORE, perf deceitfully acts as if there are no metrics to be had:
$ perf list metrics
List of pre-defined events (to be used in -e):
Metric Groups:
$
But singular 'metric' shows a list of metrics:
$ perf list metric
List of pre-defined events (to be used in -e):
Metrics:
IPC
[Instructions Per Cycle (per logical thread)]
UPI
[Uops Per Instruction]
AFTER, when asking for 'metrics', we actually see the metrics get listed:
$ perf list metrics
List of pre-defined events (to be used in -e):
Metrics:
IPC
[Instructions Per Cycle (per logical thread)]
UPI
[Uops Per Instruction]
Fixes: 71b0acce78 ("perf list: Add metric groups to perf list")

Allow users to symbolically specify L3 events for Family 17h processors
using the existing AMD Uncore driver.
Source of events descriptions are from section 2.1.15.4.1 "L3 Cache PMC
Events" of the latest Family 17h PPR, available here:
https://www.amd.com/system/files/TechDocs/55570-B1_PUB.zip
Opnly BriefDescriptions added, since they show with and without
the -v and --details flags.
Tested with:
# perf stat -e l3_request_g1.caching_l3_cache_accesses,amd_l3/event=0x01,umask=0x80/,l3_comb_clstr_state.request_miss,amd_l3/event=0x06,umask=0x01/ perf bench mem memcpy -s 4mb -l 100 -f default
