kmemtrace

Hi everybody,

As usual, the kmemtrace userspace repo is located at
git://repo.or.cz/kmemtrace-user.git

It's not updated now, but I will rebase it. So re-clone it, don't just
git-rebase it. The changes were too extensive and I'd like to keep the
revision history clean.

Changes in kmemtrace:
- new ABI, supports variable sized packets and it's much shorter (it has
specific fields for allocations)
- we'll use splice() in userspace
- replaced timestamps with sequence numbers, since timestamps don't have a good
enough resolution (though they could be added as an additional feature)
- used relay_reserve() as Mathieu Desnoyers suggested
- moved additional docs into a different commit and documented the replacement
of inline with __always_inline in those commits

Please have a look and let me know what you think.

  kmemtrace: Core implementation.
  kmemtrace: Additional documentation.
  kmemtrace: SLAB hooks.
  kmemtrace: SLUB hooks.
  kmemtrace: SLOB hooks.
