Arnaldo Carvalho de Melo 75b757ca90 perf trace: Show path associated with fd in live sessions
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.
