This cleans up dprograms_t, making it easier to read and see what chunks
are in it (I was surprised to see only 6, the explicit pairs made it
seem to have more).
This is part of the work for #26 (Record resource pointer with builtin
function data). Currently, the data pointer gets as far as the
per-instance VM function table (I don't feel like tackling the job of
converting all the builtin functions tonight). All the builtin modules
that register a resources data block pass that block on to
PR_RegisterBuiltins.
Still "some" more to go: a pile to do with transforms and temporary
entities, and a nasty one with host_cbuf. There's also all the static
block-alloc lists :/
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.
With this, the VA is very close to being safe to use in a threaded
environment (so long as each VM is used by only one thread). Just the
debug file hash and source paths to sort out.
Certain versions of qcc (fteqcc comes to mind :P) strip the names from
builtin functions. This breaks saved games that happen to have a builtin
function in a saved function variable. The earlier builtin name
reconstruction patch happened to fix the writing of save games for such
progs, and this one fixes the reading.
That is, the descriptors loaded from the progs file. Some compilers (eg,
fteqcc :P) strip builtin names from the progs, which makes debugging
difficult.
