i965,meta: Stop unlocking the texture to try and prevent deadlocks.

Unlocking the texture is not safe: another thread could come in and grab

This avoids problems with things like meta operations calling functions
that want to take the lock while the lock is already held.  Basically,

glcpp: Fix glcpp-test-cr-lf "make check" test for Mac OS X

There were two problems with the way this script used sed on OS X:

  1. The OS X sed doesn't interpret "\r" in a replacement list as a
     carriage-return character, (instead it was inserting a literal
     'r' character).

     We fix this by putting an actual ^M character into the source of
     the script, (rather than a two-character escape sequence hoping
     for sed to do the right thing).

  2. When generating the test files with LF-CR ("\n\r") newlines, the
     OS X sed was adding an undesired final newline ("\n") at the end
     of the file. We avoid this by first using sed to add the ^M
     before the newlines, then using tr to swap the \r and \n
     characters. This way, sed never sees any lines ending with
     anything but \n, so it doesn't get confused and doesn't add any
     bogus extra newlines.

glcpp: Use printf instead of "echo -n" in glcpp-test

I noticed that with /bin/sh on Mac OS X, "echo -n" does not work as
desired, (it actually prints "-n" rather than suppressing the final
newline). There is a /bin/echo that could be used (it actually works)
instead of the builtin echo.

But I decided it's more robust to just use printf rather than
hardcoding /bin/echo into the script.

i965: Flush the RC and TC before doing a fast clear resolve

The docs say "When performing a render target resolve, PIPE_CONTROL with end
of pipe sync must be delivered.", which doesn't actually tell us whether we
need to do it before or after.  Blorp did it before and after, and doing it
before certainly makes sense.  The resolve operation needs to read from the
MCS and if we don't flush the render cache it won't get up-to-date data.

On the other hand, doing it after should not be necessary, since we call
brw_render_cache_set_check_flush() after the resolve.

This gets fbo-colormask-formats working for core formats, which increases
my confidence in some of the swizzle and blend handling.

vc4: Add a helper for QOP_R4_UNPACK_[ABCD].

vc4: Don't forget to set up the offset for render targets.

This almost fixes fbo-generatemipmap rendering, except that the 1x1 level
isn't getting rendered.

vc4: Fix multi-level texture setup.

We weren't accounting for the level 0 offset in the texture setup (so it
only worked if it happened to be a single-level texture), and doing so
required that we get the level 0 offset page aligned so that the offset
bits don't get interpreted as the texture format and such.

vc4: Fix viewport handling in the uniforms upload.

I had the right viewports in vc4_emit.c, but grabbed the wrong values in
the uniform setup, so primitives would claim to be in the wrong parts of
the screen.  (The vc4_emit.c state looks like it just decides how big the
clipping guardband is).

This gets fbo-viewport closer to working (which still has the problem that
the HW is always guard-band clipping), and fixes inverted FBO rendering in
general.

clover: Refuse to build a program if there are kernel objects attached to it.

Fixes piglit cl-api-build-program.
