Nicolas Hake 092a23c2f7 Aul: Parse scripts into an AST, then generate bytecode from that 
This commit contains a fairly substantial rewrite of the C4Script code
generator. Instead of generating bytecode while parsing the script,
we're now parsing the script into a syntax tree, and have any further
processing happen on that instead of the raw source.

At this time, the code generator emits the same bytecode as the old
parser; there are several optimization opportunities that arise from the
new possibility to emit code out of order from its specification by the
author.

Compared to the old compiler, this one is still rather deficient when
dealing with incorrect code; it's also not emitting several warnings
that used to be diagnosed.

David Dormagen 771bd802f0 particles: re-added missing intialization of ibo_size 
Thanks to ck, who noticed. Apparently it got lost when reverting some changes back and forth for testing, because I had one revision where I didn't need it anymore but I reverted most of that.

The old code just appended eight spaces when the type of the BCC was
shorter than eight chars.

David Dormagen a20b7834c0 OneMillionParticles.ocs: removed some randomness in the amount of particles in the final test 
It's easier to compare runs this way.

David Dormagen 6bacdfcbb6 particles: fixed some particles not rendering under certain conditions 
Some particles were visibly missing. The reason was apparently that the VAO was initialized with an IBO that was yet too small (because not all particles were created yet).
To be honest, I don't know why the IBO needs to be rebound as the identifier itself does not change(?) but maybe OpenGL optimizes some stuff and needs the size fixed?

Steps to reproduce: In OneMillionParticles.ocs, make Test3 be the first test (otherwise the IBO would have been large enough). You would now not see all of the fireworks.

The issue was introduced in e13cda4bd0

David Dormagen 29333ef87a particles: initialize primitive restart index IBO lazily 
Otherwise the IBO is created from scratch for every particle that is e.g. created in a for loop. This is extremely slow and unnecessary.
The symptoms was that OneMillionParticles appeared to 'freeze' on the non-batch creation test. (Hint: it didn't freeze, it just took forever).

Nicolas Hake c8d71d47c0 C4CodeGen: Rename to C4AulCompiler 
I need to split up C4CodeGen into smaller parts, and having the bit that
actually generates the bytecode named C4CodeGenCodeGen would be silly.

Nicolas Hake 86729ea536 Declare C4AulBCC as class instead of struct 
The C++ standard says that it doesn't matter whether you forward declare
something as struct or class and then define it using the other keyword.
Unfortunately MSVC adds those keywords to its name mangling scheme,
which breaks things.

This unifies the lookup for local variables and functions. Its slightly
awkward that global functions can overload if and Par now, but local

C4AulParse used by both warnings and errors.

Nicolas Hake a8f4bd3960 C4AulParseError: Avoid the second string parameter 
While I'm not a big fan of hiding flow control in a function, Error()
handles formatting and saves me from calling FormatString().getData() a
lot.
