7f7c4ebbba glsl, mesa: add EXT_shader_pixel_local_storage extension
This commit also checks for and issues errors for the following:

INVALID_OPERATION is generated if the application attempts enable pixel
local storage while the value of SAMPLE_BUFFERS is one.

INVALID_OPERATION is generated if the application attempts to enable pixel
local storage while the current draw framebuffer is a user-defined frame-
buffer object and has an image attached to any color attachment other than
color attachment zero.

INVALID_OPERATION is generated if the application attempts to enable pixel
local storage while the current draw framebuffer is a user-defined frame-
buffer and the draw buffer for any color output other than color
output zero is not NONE.

INVALID_FRAMEBUFFER_OPERATION is generated if the application attempts to
enable pixel local storage while the current draw framebuffer is
incomplete.

INVALID_OPERATION is generated if pixel local storage is disabled and the
application attempts to issue a rendering command while a program object
that accesses pixel local storage is bound.

INVALID_OPERATION is generated if pixel local storage is enabled and the
application attempts to bind a new draw framebuffer, delete the currently
bound draw framebuffer, change color buffer selection via DrawBuffers, or
modify any attachment of the currently bound draw framebuffer including
their underlying storage.

63ab985511 util: Use an opaque type for linear context
In the linear allocation only the parent (context) can be used
to allocate new children, so let's use an opaque type to identify
the linear context.  This is similar to what's done in GC allocator.

Update the documentation and a couple of function names to
refer to linear context instead of linear parent.

aec516ead6 util: Remove size from linear_parent creation
None of the callsites took advantage of this, so remove
the feature.  This will help to a next change that will
add an opaque type to represent a linear parent.

0e742926c6 glsl: update default precision qualifier when it is set in the shader
Default precision qualifier for a data type could be set several times
inside a shader. This patch allows to update the default precision
qualifier for the given type that is saved in the symbol table.

If it is not in the symbol table, just add it.

6dbe8a1b9f glsl/mesa: remove unused namespace support from the symbol table
Namespace support seems to have been unused for a very long time.

Previously the hash table entry was never removed and the symbol name
wasn't freed until the symbol table was destroyed.

In theory this could reduced the number of times we need to copy a string
as duplicate names are reused. However in practice there is likely only a
limited number of symbols that are the same and this is likely to cause
other less than optimal behaviour such as the hash_table continuously
growing.

Along with dropping namespace support this change removes entries from
the hash table as they become unused.

9bea018994 glsl: use var with initializer on global var validation
Currently, when cross validating global variables, all global variables
seen in the shaders that are part of a program are saved in a table.

When checking a variable this already exist in the table, we check both
are initialized to the same value. If the already saved variable does
not have an initializer, we copy it from the new variable.

Unfortunately this is wrong, as we are modifying something it is
constant. Also, if this modified variable is used in
another program, it will keep the initializer, when it should have none.

Instead of copying the initializer, this commit replaces the old
variable with the new one. So if we see again the same variable with an
initializer, we can compare if both are the same or not.
