This reverts commit 2919c3fdb4.
For formats like BGRX, looping through 0..num_components works fine.
But for formats like XRGB, we'd check the color mask for X and fail to
check it for B.
The SIMD16 replicated FB write message only works if we don't need the
color calculator to mask our framebuffer writes. Previously, we bailed
on it if color_mask wasn't <true, true, true, true>. However, this was
needlessly strict for formats with fewer than four components - only the
components that actually exist matter.
WebGL Aquarium attempts to clear a BGRX texture with the ColorMask set
to <true, true, true, false>. This will work perfectly fine with the
replicated data message; we just bailed unnecessarily.
Improves performance of WebGL Aquarium on Iris Pro (at 1920x1080) by
abound 40%, and Bay Trail (at 1366x768) by over 70% (using Chrome 24).

The conversion code for srgb was tuned for n x 4x8bit AoS -> 4 x nxfloat SoA
(and vice versa), fix this to handle also 16bit 565-style srgb formats.
Still not really all that generic, things like r10g10b10a2_srgb or
r4g4b4a4_srgb wouldn't work (the latter trivial to fix, the former would not
require more work to not crash but near certainly need some higher precision
calculation) but not needed right now.
The code is not fully optimized for this (could use more direct calculation
instead of expanding to 8-bit range first) but should be good enough.

GL generally doesn't seem to allow srgb formats with less (or more) than 8 bit
for the rgb channels, though some hw could easily do it (typically for formats
with up to 10 bits for the rgb channels, at least for formats with less than 8
bits support is likely widespread even). While it may be true there aren't
really any benefits for such formats, we need for it for d3d, though luckily
only for b5g6r5_srgb it seems.
So add this format along with the util code for conversion - since that util
code is heavily tuned for 8bit srgb this isn't really all that well optimized
and rounding doesn't seem right but at least it should give some halfway
meaningful results.

In the gallium code, the assert() macro could come from either the
system's assert.h file (via c11/threads.h) or from gallium's u_debug.h.
It looks like all known assert.h files unconditionally #undef assert
before defining their own version. So the assert you get depends on
whether threads.h or u_debug.h was included last.
In the gallium code we really want to use the assert() from u_debug.h
(it behaves better on Windows). In gallium, c11/threads.h is only
included after u_debug.h in the os_thread.h wrapper. So Adding
an #ifndef assert test in the threads*.h files avoids using the system's
assert().
