[v2,0/4] libmemusage code cleanup

  These cleanups come from reviewing the OpenRISC submission. The
libmemusage requires duplicate definition and adds a lot of boilerplate
code: its internal atomics can be replaces by generic types, which
allows remove a lof of atomic-machine.h types; the internal time can be
replaced with hp-timing.h, and for stack pointer information we can use
either the __thread_stack_pointer (hurd) or CURRENT_STACK_FRAME (Linux).

---
v2: Use generic types instead of C11 atomic ones.
---

Adhemerval Zanella (4):
  malloc: Remove atomic_* usage
  Remove atomic-machine.h atomic typedefs
  malloc: Use hp-timing on libmemusage
  malloc: Remove memusage.h
