31ea3814bb [qfcc] Decouple type encoding from the pr struct
This will allow encoding types correctly in the linker.

54a9305dbf [qfcc] Use right object for sizeof
Since the bitfield has been abandoned, can use sizeof on the field
again.

Not knowing if a blank line is an empty string or spaces...

f224eadbb8 [qfcc] Rework QuakeC function type manging
It is now "consistent" with the rest of the type building in that it
uses find_type(append_type(return, params)) like the C version, thus
allowing append_type to do its thing with type aliases. This fixes the
overload test.

69037fe5eb [qfcc] Strip alias info off function params
For now. This fixes many problems but does lose type aliasing info from
function parameters.

da39e675b8 [qfcc] Copy type chain for type aliases
The full_type branch of an alias splitter (alias with null name) needs
to mirror the clean side up to the type alias. It is causing problems
with functions, but that's expected because parameters complicate
things.

ec3c2426ff [qfcc] Add type dot dumping
It's not connected up yet because I'm unsure of just where to put things
(it gets messy fast), but just being able to see the structure of
complex types is nice.

8479cad8a8 [qfcc] Record alias-free type in function_t
This eases type unaliasing on functions a little.

Still more to to go, but this fixes a really hair-pulling bug: linux's
heap randomiser was making the typedef test fail randomly whenever
typedef.qfo was compiled.

1eef2a8b5e [qfcc] Implement type aliasing again
When a type is aliased, the alias has two type chains: the simple type
chain with all other aliases stripped, and the full type chain. There
are still plenty of bugs in it, but having the clean type chain takes
care of the major issue that was in the previous attempt as only the
head of the type-chain needs to be skipped for type comparison.

Most of the bugs are in finding the locations where the head needs to be
skipped.

c6483b617c [qfcc] Remove obsolete notes
nil seems to have sorted himself out with the recent reworking of how
qfcc handles nil.

fdf6fac077 [qfcc] Rewrite expr_nil to use memset if necessary
This fixes the problem with returning nil through @param (and probably
structs in general).

643711ef40 [qfcc] Pre-initialize type_object's strct pointer

ab3d91f0c3 [qfcc] Clean up simple type checking
All simple type checks are now done using is_* helper functions. This
will help hide the implementation details of the type system from the
rest of the compiler (especially the changes needed for type aliasing).

8b1e4eea58 [qfcc] Bring back the core of type aliasing

75394cc4f8 [gamecode,qfcc] Use enums for type encoding types
The enums are forced to 32 bits via bitfield spec, so can't use sizeof
on them, but this makes switch enum checks work in gcc.

1f8cc7186c [qfcc] Hide "function" type behind an @

4cef9792f4 [util] Make hash-tables semi-thread-safe
They take a pointer to a free-list used for hashlinks so the hashlink
pools can be per-thread. However, hash tables that are not updated are
always thread-safe, so this affects only updates. progs_t has been set
up such that it is easy for multiple progs within one thread can share
hashlinks.

16bda66785 [qfcc] Add more statement types for move/memset

3c2f6c8447 [qfcc] Simplify flow_analyize_pointer_operand
and its usage. The parts of flow_analyze_statement that use it know
where the returned operand needs to go. Unfortunately, this breaks dags
pretty hard, but that's because dags needs to learn about the fancy
assignment-type statements.
