To preserve the KPI, the previous operations are mapped to the write
lock macros. The lock is still kept as a mutex for now.

It turns out our GCC has quite an interesting bug:
typeof(1.0fi) != float _Complex
typeof((float _Complex)1.0fi) != float _Complex
typeof((float _Complex)1.0i) == float _Complex
In other words: if casting to an equal size, GCC seems to take a
shortcut. By casting down from a double to a float, GCC doesn't take
this shortcut, yielding the proper type.
To prevent foot-shooting, add a _Static_assert() to guarantee that
_Complex_I is always a float _Complex. I'm not going to MFC this part of
the diff.

The macro construction used now, is almost identical to the code
provided in C11 proposal N1404. This new version doesn't seem to
introduce any regressions according to the regression test in tools/,
but still seems to malfunction with Clang on certain aspects.
The new code does work successfully with GCC 4.2, 4.6 and 4.7. With 4.7,
it also works when __generic() is implemented on top of _Generic().

Already introducing this allows us to be forward compatible with C11
compilers. By implementing <tgmath.h> on top of this interface, it
becomes trivial to support both our existing GCC and newer compilers.
This allows people to still write statically linked applications that
call strchr() or strrchr() and have a local variable or function called
index.

For now, AH_SUPPORT_AR5416 is required, so I'll just fix any

1. Only 12-bit VLAN Identifiers, not full 16-bit VLAN tags can be set using

2. When we mean VLAN Identifiers, spell it that way, rather than as VLAN tag.

only changed when the object is marked as OBJ_MIGHTBEDIRTY. For async

all pages are cleared after the vm_object_page_clean() returned.
