[PATCH 5/9] perf, tools: Add perf download to download event files v3
From: Andi Kleen Add a downloader to automatically download the right files from a download site. This is implemented as a script calling wget, similar to perf archive. The perf driver automatically calls the right binary. The downloader is extensible, but currently only implements an Intel event download. It would be straightforward to add other sites too for other vendors. The downloaded event files are put into ~/.cache/pmu-events, where the builtin event parser in util/* can find them automatically. v2: Use ~/.cache v3: Check for wget. Some cleanups.
