perf, tools: Add perf download to download event files
Add a downloader to automatically download the right
files from a download site.
This is implemented as a script calling curl, 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.
v4: Improve manpage.
v5: Due to popular demand use curl instead of wget.
