assembler: Mark format() as PRINTFLIKE in the disassembler

So when making changes in code using that function, we get warnings
about mismatches between the format string and arguments.

dest_horizontal_stride needs go through the horiz_stride[] indirection

assembler: Don't use GL types

sed -i -e 's/GLuint/unsigned/g' -e 's/GLint/int/g' \

       -e 's/GLshort/int16_t/g' assembler/*.[ch]

Drop the GL types here, they don't bring anything to the table. For
instance, GLuint has no guarantee to be 32 bits, so it does not make too
much sense to use it in structure describing hardware tables and
opcodes.

Of course, some bikeshedding can be applied to use uin32_t instead, I
figured that some of the GLuint are used without size constraints, so
a sed with uint32_t did not seem the right thing to do. On top of that
initial sed, one bothered enough could change the structures with size
constraints to actually use uint32_t.
