33ff10ea55 Add a macro that gets the physical address of a memory mapped device 
register from a bus space resource.

Note that this macro is just for ARM, and is intended to have a short
lifespan.  The DMA engines in some SoCs need the physical address of a
memory-mapped device register as one of the arguments for the transfer.
Several scattered ad-hoc solutions have been converted to use this macro,
which now also serves to mark the places where a more complete fix needs
to be applied (after that fix has been designed).

b3a9841934 Link libgcc_s against compiler-rt on ARM EABI. This allows us to use all of 
the symbols in compiler-rt, including the ones not available in the old
libgcc. This fixes the build with clang which generates calls to funstions
that are missing from libgcc_s.

943c3bb968 Require CAP_SEEK if both O_APPEND and O_TRUNC flags are absent. 
In other words we don't require CAP_SEEK if either O_APPEND or O_TRUNC flag is
given, because O_APPEND doesn't allow to overwrite existing data and O_TRUNC
requires CAP_FTRUNCATE already.

5368b81eb0 Contrary to what the deleted comment said, the m_move_pkthdr() 
will not smash the M_EXT and data pointer, so it is safe to
pass an mbuf with external storage procuded by m_getcl() to
m_move_pkthdr().

302868d914 Fix two bugs: 
* when pulling frames off of the TID queue, the ATH_TID_REMOVE()
  macro decrements the axq_depth field.  So don't do it twice.

* in ath_tx_comp_cleanup_aggr(), bf wasn't being reset to bf_first
  before walking the buffer list to complete buffers; so those buffers
  will leak.
