For live sessions we can just access /proc to map an fd to its path, on
a best effort way, i.e. sometimes the fd will have gone away when we try
to do the mapping, as it is done in a lazy way, only when a reference to
such fd is made then the path will be looked up in /proc.
This is disabled when processing perf.data files, where we will have to
have a way to get getname events, be it via an on-the-fly 'perf probe'
event or after a vfs_getname tracepoint is added to the kernel.
A first step will be to synthesize such event for the use cases where
the threads in the monitored workload exist already.

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.

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
