[PATCH 1/2] perf archive: Add new option '--all'

[vmolnaro@redhat.com]

From: Veronika Molnarova <vmolnaro@redhat.com>

Perf archive has limited functionality and people from Red Hat Global
Support Services sent a request for a new feature that would pack
perf.data file together with an archive with debug symbols created by
the command 'perf archive' as customers were being confused and often
would forget to send perf.data file with the debug symbols.

Perf archive now accepts an option '--all' that generates archive
'perf.all-hostname-date-time.tar.bz2' that holds file 'perf.data' and
a sub-tar 'perf.symbols.tar.bz2' with debug symbols. The functionality of
the command 'perf archive' was not changed.
