Subject: [PATCH 3/7] perf record: make the record options available outside perf record

From: Tom Zanussi <tom.zanussi@...ux.intel.com>

Other perf commands that invoke perf record, such as perf trace, may
want to reuse the options used by perf record.

This makes them non-static and renames them to avoid clashes with
other 'options' variables.
