Add perf_dlfilter_fns.al_cleanup() to do addr_location__exit() on data
passed via perf_dlfilter_fns.resolve_address().
Add dlfilter-test-api-v2 to the "dlfilter C API" test to test it.
Update documentation, clarifying that data returned by APIs should not
be dereferenced after filter_event() and filter_event_early() return.

Add machine_pid and vcpu to struct perf_dlfilter_sample. The 'size' can be
used to determine if the values are present, however machine_pid is zero if
unused in any case. vcpu should be ignored if machine_pid is zero.

Move perf_dlfilters.h in the source tree so that it will be found when
building dlfilters as part of the perf build.
