Previously, the rule deleted by this commit was matched every single
time (being the longest match). If not skipping, it used REJECT to
continue on to the actual correct rule.
The flex manual advises against using REJECT where possible, as it is
one of the most expensive lexer features. So using it on every match
seems undesirable. Perhaps more importantly, it made it necessary for
the #if directive rules to contain a look-ahead pattern to make them
as long as the (now deleted) "skip the whole line" rule.
This patch introduces an exclusive start state, SKIP, to avoid REJECTs.
Each time the lexer is called, the code at the top of the rules section
will run, implicitly switching the state to the correct one.
Fixes piglit tests 16384-consecutive-chars.frag and
16385-consecutive-chars.frag.
The expected result has been out of sync with what glcpp produces for
some time; glcpp's actual result seems to be correct and is very close to
GCC's cpp. Updating this will make it easier to catch regressions in
upcoming commits.
This commit is basically a copy-over of the fix
Chia-I Wu's commited to wayland:

"Workaround an xcb-dri2 bug.
xcb_dri2_connect_device_name generated by xcb-proto 1.6 is broken.
It only works when the length of the driver name is a multiple of 4."
This reverts commit 1f9a0a4e6e.
This caused trouble with Lightsmark w/ i965 driver and fbo/fbo-blit-d24s8
(see bug 34894). It's probably something simple but no time to debug now.
SNB has 64k urb space, we only use piece of them.
The more urb space we alloc,
the more concurrent vs threads we can run.
push the urb space usage to the limit.

this fixes fbo-generatemipmap-formats rgtc and s3tc in NPOT mode
with softpipe.
r600g fails to even get level 0 correct so have to look into that
a bit further.

This was always converting to 8-bit per channel unsigned formats,
which isn't suitable for RGTC signed formats, this special cases
those two formats and converts to floats for those.

SNORM needs a bit of work in the state tracker in order for mipmap
generation to work I believe.
I'm also not sure that having unorm fetches for an snorm format is
sane.
With signed types we weren't hitting this test however the comment
stating this doesn't happen often doesn't apply when using signed
types since an all 0 block is quite common which isn't abs min or max.
this fixes the limits correctly again also.

if the values are all in the last dword, the high bits can be 0,
This fixes a valgrind warning I saw when playing with mipmaps.

Drivers can call this function as needed. It tells the VBO module to
always unmap the current glBegin/glEnd VBO when we flush. Otherwise
it's possible to be in a flushed state but still have the VBO mapped.
