17355f716b treewide: use UTIL_DYNARRAY_INIT
Instead of util_dynarray_init(&dynarray, NULL), just use
UTIL_DYNARRAY_INIT instead. This is more ergonomic.

Via Coccinelle patch:

    identifier dynarray;

    -struct util_dynarray dynarray = {0};
    -util_dynarray_init(&dynarray, NULL);
    +struct util_dynarray dynarray = UTIL_DYNARRAY_INIT;

Followed by sed:

    bash -c "find . -type f -exec sed -i -e 's/util_dynarray_init( &\(.*\), NULL )/\1 = UTIL_DYNARRAY_INIT/g' \{} \;"
    bash -c "find . -type f -exec sed -i -e 's/util_dynarray_init(\(.*\), NULL)/*\1 = UTIL_DYNARRAY_INIT/g' \{} \;"

b824ef83ab util/dynarray: infer type in append
Most of the time, we can infer the type to append in
util_dynarray_append using __typeof__, which is standardized in C23 and
support in Jesse's MSMSVCV. This patch drops the type argument most of
the time, making util_dynarray a little more ergonomic to use.

This is done in four steps.

First, rename util_dynarray_append -> util_dynarray_append_typed

    bash -c "find . -type f -exec sed -i -e 's/util_dynarray_append(/util_dynarray_append_typed(/g' \{} \;"

Then, add a new append that infers the type. This is much more ergonomic
for what you want most of the time.

Next, use type-inferred append as much as possible, via Coccinelle
patch (plus manual fixup):

    @@
    expression dynarray, element;
    type type;
    @@

    -util_dynarray_append_typed(dynarray, type, element);
    +util_dynarray_append(dynarray, element);

Finally, hand fixup cases that Coccinelle missed or incorrectly
translated, of which there were several because we can't used the
untyped append with a literal (since the sizeof won't do what you want).

All four steps are squashed to produce a single patch changing every
util_dynarray_append call site in tree to either drop a type parameter
(if possible) or insert a _typed suffix (if we can't infer). As such,
the final patch is best reviewed by hand even though it was
tool-assisted.

No Long Linguine Meals were involved in the making of this patch.

5d0050c8bf util/dag: Add a validation function.
I experienced a circular dag in freedreno, and wanted a way to see what
was going wrong.

984aa0ac9a util/dag: Move the callback function pointer to the state.
No sense passing it as a recursive argument when we have this storage
right there.

This will be useful for when the edge data represents a delay of some
sort, like it will with ir3.

508f917d8c util/dag: Make edge data a uintptr_t
Nobody was actually using it as a pointer, and I'm going to introduce a
shared function which relies on it not being a pointer so let's fix this
once and for all.

dcf1d8d7a4 util: Replace recursive DFS with iterative implementation
Doesn't fix, but improves the situation in issue #5163. The
VK.spirv_assembly.instruction.graphics.spirv_ids_abuse.lots_ids_* tests
emit about 160k instructions. ir3_sched blows out the stack after
dag_traverse_bottom_up_node reaches a depth of about 130k frames.

This patch replaces the recursively-implemented post-order traversal
with an iterative implementation using a stack, allowing us to process
DAGs as large as memory can hold.

Definitely makes you appreciate the elegance of recursion...
