[PATCH 16/35] perf record: Rename 'perf_record' to plain 'record'

[Arnaldo Carvalho de Melo]

From: Arnaldo Carvalho de Melo <acme@xxxxxxxxxx>

Its a local struct and the functions use the __ separator from the class
name to the method name, so its unlikely that this will clash with other
namespaces.

Save some typing then.
