...
It looks like a munged commit, but I think I had decided that it was
best to make cvar access explicit.

[cexpr] Use ` to allow identifiers to start with a number
...
The generated short names for a lot of Vulkan enums start with a number
(eg VK_IMAGE_TYPE_2D -> 2d). Having to prefix the short name with ` is a
tiny cost for the convenience.

[cexpr] Support variable assignment
...
I might have to add code to block it when necessary, but it's needed for
axis recipe parsing.

[util] Correct the lex priority for int constants
...
The actual need to specify unsigned int constant is a bit of a pain, but
not being able to do so due to lex priority errors is even more of a
pain.

[util] Propagate cexpr errors back to the caller

Not much point in error detection when it's ignored.

[util] Add a mini expression parser
...
It is capable of parsing single expressions with fairly simple
operations. It current supports ints, enums, cvars and (external) data
structs. It is also thread-safe (in theory, needs proper testing) and
the memory it uses can be mass-freed.
