This reverts commit 962a1c07b4.
Further testing revealed that this commit can cause the pre-processor to enter
infinite loops. For now, simply revert this code until a cleaner,
better-tested version is available.
Previously, we were only supporting line-continuation backslash characters
within lines of pre-processor directives, (as per the specification). With
OpenGL 4.2 and GLES3, line continuations are now supported anywhere within a
shader.
While changing this, also fix a bug where the preprocessor was ignoring
line continuation characters when a line ended in multiple backslash
characters.
The new code is also more efficient than the old. Previously, we would
perform a ralloc copy at each newline. We now perform copies only at each
occurrence of a line-continuation.

When a client frame callback is executed and the client starts rendering
again, the egl event queue might not have been dispatched so that the
buffer release event for the previous frame hasn't been processed. In
that case a third buffer is allocated, even though it would be possible
to reuse the buffer that was just released.
The wl_display_dispatch_queue_pending() entry point is available from
wayland-client 1.0.2, so require that in configure.ac. Also, just
let the pkg-config macro throw its own error, which will show what version
we were looking for and failed to find.

Commit ca3ed3e024 fixed the problem where
eglMakeCurrent would trigger a getbuffer callback that then breaks the
following wl_egl_window_resize() call. However, we still need to
invalidate buffers in eglSwapBuffers, since in wayland we always swap
buffers, so the dri driver needs to come out and ask us for the next buffer
after each swapbuffer.
Note: this is a candidate for stable branches.

These helper macros save you from writing nasty expressions like:
if ((inst->src[1].type == BRW_REGISTER_TYPE_F &&
inst->src[1].imm.f == 1.0) ||
((inst->src[1].type == BRW_REGISTER_TYPE_D ||
inst->src[1].type == BRW_REGISTER_TYPE_UD) &&
inst->src[1].imm.u == 1)) {
Instead, you simply get to write inst->src[1].is_one(). Simple.
Also, this makes the FS backend match the VS backend (which has these).
This patch also converts opt_algebraic to use the new helper functions.
As a consequence, it will now also optimize integer-typed expressions.

We used to invalidate the drawable after a call to eglSwapBuffers(),
so that a wl_egl_window_resize() would take effect for the next frame.
However, that leads to calling dri2_get_buffers() when eglMakeCurrent()
is called with the current context and surface, and a later call to
wl_egl_window_resize() would not take effect until the next buffer
swap.
Instead, add a callback from wl_egl_window_resize() back to the wayland
egl platform, and invalidate the drawable only when it is resized.
This solves a bug on wayland clients when going back to windowed mode
from fullscreen when clicking a pop up menu, where the window size
after this would be the fullscreen size.
Note: this is a candidate for stable branches.

Completely forgot about updating Makefile when removing it. Stephane
already fixed the make build, but there were a few mentions of
lp_tile_soa left in the tree.
The gen4 simd16 workaround looks at ir->type to determine how much
storage to allocate for the simd16 value. In fragment programs,
texturing only ever returns float vec4s (unlike GLSL, which can also
have scalar floats or vector integers), so this is the right type.

This test file is very similar to test 113-line-and-file-macros but uses token
pasting for cleaner quiz answers (without spaces between the digits). This
test passes thanks to the recent addition of support for pasting INTEGER
tokens, (but would have failed without that).
(Note that this test is distinct from test 059-token-pasting-integer which
pastes integers parsed from the source. Those are parsed to INTEGER_STRING
tokens and are already pasted correctly as verified by that test. The only way
to generate the INTEGER tokens which currently fail to paste is with an
internal define such as __LINE__ that results in an integer.)

Since we don't support render target indices rendering to array textures
is still restricted to a single layer at a time.
Also, the min/max layer in the sampler view (which is unnecessary for GL)
is ignored (always use all layers).
