perf data: Support single perf.data file directory
Support directory output that contains a regular perf.data file, named
"data". By default the directory is named perf.data i.e.
perf.data
└── data
Most of the infrastructure to support a directory is already there. This
patch makes the changes needed to support the format above.
Presently there is no 'perf record' option to output a directory.
This is preparation for adding support for putting a copy of /proc/kcore in
the directory.
