====================
bpf: Add uprobe session support

hi,
this patchset is adding support for session uprobe attachment and
using it through bpf link for bpf programs.

The session means that the uprobe consumer is executed on entry
and return of probed function with additional control:
  - entry callback can control execution of the return callback
  - entry and return callbacks can share data/cookie

Uprobe changes (on top of perf/core [1] are posted in here [2].
This patchset is based on bpf-next/master and will be merged once
we pull [2] in bpf-next/master.

v9 changes:
  - rebased on bpf-next/master with perf/core tag merged (thanks Peter!)

thanks,
jirka
