[PATCH v2 0/4] talloc and memory leak debugging

[Sascha Hauer <s.hauer@pengutronix.de>]

This picks up the talloc series previously sent by Ahmad. I also added
the memory leak debugging patch tooling for sandbox.

This series includes my review comments to v1.

Changes since v1:
- pass originally allocated pointer to malloc_usable_size()
- align talloc allocations to 8 bytes
- Use __lsan_do_recoverable_leak_check() instead of
  __lsan_do_leak_check() to keep barebox running after memory leaks have
  been detected
