795021e229 [util] Record allocated blocs for ALLOC
Recording the blocks makes it possible to free them later. As a
convenience, ALLOC_STATE declares the freelist and blocks vars needed by
ALLOC.

f4ae24e0e0 [qfcc] Support alignment in qfo spaces
The alignment is specified as a power of 2 (ie, actual alignment = 1 <<
alignment) allowing old object files to be compatible (as their
alignment is 0). This is necessary for (in part for #30) as it turned
out even global vectors were not aligned correctly.

Currently, only data spaces even vaguely respect alignment. This may
need to be fixed in the future.

be4021f8f4 [qfcc] Actually shrink the unaligned hole
This fixes the duplicate allocation caused by an exact fit aligned alloc
in an unaligned hole where the padding remains free.

a19349b242 [qfcc] Allow 0 sized highwater allocations in defspaces
This turned out to be needed for functions with no parameters (or no
locals).

17dfd1492f [qfcc] Make virtual defspaces useful for highwater allocation
This seems to be the most reasonable approach to allocating space for
function call parameters without using push and pop (or adding to the
stack pointer), though it's probably good even when using push and pop
to help keep things aligned.

6d5ffa9f8e [build] Move to non-recursive make
There's still some cleanup to do, but everything seems to be working
nicely: `make -j` works, `make distcheck` passes. There is probably
plenty of bitrot in the package directories (RPM, debian), though.

The vc project files have been removed since those versions are way out
of date and quakeforge is pretty much dependent on gcc now anyway.

Most of the old Makefile.am files  are now Makemodule.am.  This should
allow for new Makefile.am files that allow local building (to be added
on an as-needed bases).  The current remaining Makefile.am files are for
standalone sub-projects.a

The installable bins are currently built in the top-level build
directory. This may change if the clutter gets to be too much.

While this does make a noticeable difference in build times, the main
reason for the switch was to take care of the growing dependency issues:
now it's possible to build tools for code generation (eg, using qfcc and
ruamoko programs for code-gen).

ca0b03687f Change the naming of ALLOC's free-list.
Rather than prefixing free_ to the supplied name, suffix _freelist to the
supplied name. The biggest advantage of this is it allows the free-list to
be a structure member. It also cleans up the name-space a little.

eb8fd55677 Move set.c into libQFutil.
Also move the ALLOC/FREE macros from qfcc.h to QF/alloc.h (needed to for
set.c).

Both modules are more generally useful than just for qfcc (eg, set
builtins for ruamoko).

0585471723 Make defspaces typed.
Simply "backed" and "virutal". Backed spaces have memory allocated to them
while virtual spaces do not. Virtual spaces are intended for local
variables and entity fields.

c7b2996798 Use the correct algorithm for the new defspace size.
While the result was correct, space->size >= space->size is always true and
thus grow_space would unconditionally increase the defspace's size.

d340aac2eb Fix the bugs marked in defspace.h
Now size is checked properly for defspace_free_loc and defspace_alloc_loc,
and defspace_alloc_loc check's grow()'s return value.

98a0afa38f Add and use FREE() to complement ALLOC().
Now it will be easy to test memory access with valgrind (just compile with
DEBUG_QFCC_MEMORY defined).

79c1a8f37a Use internal_error instead of error/exit(1).
Heh, an abort hiding in disguise :)

23a38738fc Massive whitespace cleanup.
Lots of trailing whitespace and otherwise blank lines.

bc1b483525 Nuke the rcsid stuff.
It's pretty useless in git.

f1d9570dc8 Fix constant value type handling.
Rename immediate.[ch] to value.[ch] and clean up the mess.

Add convert_value() to convert the type of a value (only scalar types).

d80a3413e5 Fix a segfault when freeing locations.
When chasing linked lists with a double pointer, must check the first
dereference and not the pointer itself.

27c5139612 Give defspaces some backing memory.
I'm not sure I want all defspaces to have backing memory, but this will do
for now.

afc5b2827d Simplify def handling, use far data.
Since there is now a proper symbol table, defs are now just references to
memory locations and the symbol table takes care of duplicates.

Also, start using far data for ObjQC structures.

The qfo functions have been stubbed out until I figure out what to do with
object files in the new scheme.

85de101aa3 Break out the defspace code.
This also makes some improvements to the free block handling code.
