YYLEX_PARAM is no longer supported as of Bison 3.0. Instead, the Bison
developers recommend using %lex-param.
%lex-param takes a type and variable name, similar to %parse-param,
so you can't pass an arbitrary expression like state->scanner. But Flex
insists on passing the actual scanner object, not an arbitrary object
like state.
To solve this, the parser defines a wrapper lex() function which accepts
"state," and calls Flex's lex() function with state->scanner.
Fixes the build with Bison 3.0. Also works with Bison 2.7.1.

I had removed it in commit 1e7776ca2b
because it was obviously wrong -- why do we care whether the server is a
version that emits events, if we're not watching for the server's events,
anyway? And why would you only invalidate on a server that emits
invalidate events, when the comment said to emit invalidates if the server
*doesn't*? Only, I missed that we otherwise don't flag that our buffers
might have changed at swap time at all, so the driver was only checking
for new buffers when triggered by the Viewport hack. Of course you don't
expect Viewport to be called after a swap.
So, this is effectively a revert of the previous commit, except that I
dropped the check for only emitting invalidates on a new server -- we
*always* need to invalidate if we're doing a SwapBuffers.

Previously we were using truncation, which gives the correct result
only for numbers in [0.5-1.0] range (because there's no mantissa bits
to do any rounding there).
This is frequently hit (and probably only used there) when converting
fragment depth to depth format (d24s8 etc.) or otherwise dealing with
depth format.
v2: as spotted by Jose, get rid of extra type (src_type is already unsigned).

The code that checks if some texture target is valid for

glTexStorage*() functions make textures immutable. This carries on to
proxy textures. Error checking in texture storage functions prevents
proxy textures from working after first time because internally, they
became immutable.
This commit makes the error checking ignore the immutability flag when
working with proxy textures.

When working with the glTexStorage*() functions, the error checking
checks that a non-default (i.e., non-zero) texture is currently bound.
However, this check made glTexStorage*() functions fail with proxy
textures when the default texture is bound. Proxy textures do not care
about the current texture bindings so for them this check should not
be done.

The function _mesa_get_tex_max_num_levels() is supposed to calculate
the number of mipmap levels but it was not written to handle proxy

this, at least glTexStorage*() calls would incorrectly fail when used
with proxy textures with more than one mipmap level.

This patch changes link_shaders() so that it sets prog->LinkStatus to
true when it starts, and then relies on linker_error() to set it to
false if a link failure occurs.
Previously, link_shaders() would set prog->LinkStatus to true halfway
through its execution; as a result, linker functions that executed
during the first half of link_shaders() would have to do their own
success/failure tracking; if they didn't, then calling linker_error()
would add an error message to the log, but not cause the link to fail.
Since it wasn't always obvious from looking at a linker function
whether it was called before or after link_shaders() set
prog->LinkStatus to true, this carried a high risk of bugs.
