Currently the srcline sort key compares ip rather than srcline info. I
guess this was due to a performance reason to run external addr2line
utility. Now we have implemented the functionality inside, use the
srcline info when comparing hist entries.
Also constantly print "??:0" string for unknown srcline rather than
printing ip.

When the srcline sort key is used , the external addr2line utility needs
to be run for each hist entry to get the srcline info. This can consume
quite a time if one has a huge perf.data file.
So rather than executing the external utility, implement it internally
and just call it. We can do it since we've linked with libbfd already.

number, like:
$ perf record -m 8K ls
$ perf record -m 2M ls

While perf-lock currently reports both the total wait time and the
number of contentions, it doesn't explicitly show the average wait time.
Having this value immediately in the report can be quite useful when
looking into performance issues.
Furthermore, allowing report to sort by averages is another handy
feature to have - and thus do not only print the value, but add it to
the lock_stat structure.

This function should be straightforward, and we can remove some trivial
logic by moving the functionality of read_events() into __cmd_report() -
thus allowing a new session to be properly deleted.
Since the 'info' subcommand also needs to process the recorded events,
add a 'display_info' flag to differentiate between report and info
commands.
Furthermore, this patch also calls perf_session__has_traces(), making
sure that we don't compare apples and oranges, fixing a segfault when
using an perf.data file generated by a different subcommand. ie:
./perf mem record sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.017 MB perf.data (~724 samples) ]
./perf lock report
Segmentation fault (core dumped)

This way we make the output more compact.
If somebody complain (and provide a sane reason why we would like to see
zeroes) we can make it an optional, ~/.perfconfig configurable knob.

Current timestamp shown for output is time relative to firt sample. This
patch adds an option to show the absolute perf_clock timestamp which is
useful when comparing output across commands (e.g., perf-trace to
perf-script).

Taking into account the fact that the SOCK_ types can be overriden for
ABI reasons on MIPS and also masking and interpreting the socket flags
(NONBLOCK and CLOEXEC), printing whatever is left in the flags bits
as an hex number, or'ed.

This is just for the low hanging fruit 'cmd' arg, a proper beautifier
will as well use arg->mask to ignore the third arg for some of the
