Subject: [PATCH 11/13] perf util: Make copyfile_offset() global

From: Jiri Olsa <jolsa@...nel.org>

It will be used outside of util object in following patches.

Committer note:

We need to have the header with the definition for loff_t in util.h
since we now use it in the copyfile_offset() signature.

Also move that prototype closer to the other copyfile_ prefixed
functions.
