The verbose debug output from the parser is quite useful when debugging, and
having this available as a command-line option is much more convenient than
manually forcing this into the code when needed, (which is what I had been
doing for too long previously).

The -p option we now use when calling bison means that this variable will be
named glcpp_parser_debug not yydebug. This was not caught when the -p option
was added because this variable isn't used in the code as committed. (I prefer
the declaration to remain since it allows a developer to easily find this
variable name to enable debugging.)

Fixes a regression since b2d1c579 where ES shaders without a #version
declaration would fail to compile if their precision declaration was
wrapped in the standard #ifdef GL_ES check.

This will allow testing of disabled line-continuation on a case-by-case basis,
(with the option communicated to the preprocessor via the GL context).

As the preprocessor becomes more sophisticated and gains more optional
behavior, it's easiest to just pass the GL context pointer to it so that
it can examine any fields there that it needs to (such as API version,
or the state of any driconf options, etc.).

This should help avoid confusion now that we're using the gl_api enum
to distinguishing between core and compatibility API's. The
corresponding enum value for core API's is API_OPENGL_CORE.

This symbol with dricore escapes into the namespace, its too generic,
we should prefix it with something just to be nice.
Should be applied to stable + 9.0

Previously _LinkedShaders was a compact array of the linked shaders
for each shader stage. Now it is arranged such that each slot,
indexed by the MESA_SHADER_* defines, refers to a specific shader
stage. As a result, some slots will be NULL. This makes things a
little more complex in the linker, but it simplifies things in other
places.
As a side effect _NumLinkedShaders is removed.
NOTE: This may be a candidate for the 7.9 branch. If there are other
patches that get backported to 7.9 that use _LinkedShader, this patch
should be cherry picked also.

Also define it if #version 100 is encountered.

Previously glcpp would silently abort if it couldn't fstat the file being
read, (so it would work with stdin redirected from a file, but would not
work with stdin as a tty). The stat was so that glcpp could allocate
a buffer for the file content in a single call.
We now use talloc_realloc instead, (even if the fstat is
possible). This is theoretically less efficient, but quite irrelevant,
(particularly because the standalone preprocessor is used only for
testing).

This error message was missing so that the program would simply
segfault if the provided filename could not be opened for some reason.
While we're at it, we add explicit support for a filename of "-" to
indicate input from stdin.

This is useful for debugging the preprocessor.

The only optional extension currently supported by the compiler is
GL_EXT_texture_array.
