This commit basically reverts commit 5b954f8f9. The problem of nested
iterations hasn't been fixed in the mean time, but since the GC can
run arbitrary ELisp code (via `post-gc-hook`), running the GC from
within an itree iteration is already unsafe anyway :-(
* src/alloc.c (mark_overlays): Delete function.
(mark_buffer): Use ITREE_FOREACH.
* src/itree.c (interval_generator_ensure_space, interval_generator_reset):
Inline and then delete functions.
(interval_tree_inherit_offset): Only take the tree's `otick` as arg.
Update all callers.
(struct interval_generator): Remove `tree` field, replace with a copy
of the tree's `otick`.
(interval_stack_push_flagged): The arg should be a real node.
(interval_tree_insert_gap): Prefer checking root==NULL rather than size==0.
Skip loop when tree is empty to avoid pushing&processing the NULL node.
(interval_tree_inherit_offset): Prefer parent==NULL rather than
node==root to avoid accessing the tree object.
* src/buffer.c (delete_all_overlays): Add comment.
* src/itree.c (struct interval_generator): New fields `running`,
`file`, and `line` moved from `interval_tree`.
(interval_stack_push_flagged): Adjust comment to resolve a FIXME.
(interval_tree_clear): Replace assignment with an a
(interval_tree_iter_next): Delete function.
(interval_tree_clear): Don't set `iter_running` here any more.
(interval_generator_create): Set it here instead.
(interval_tree_iter_start): Fetch `iter` once and for all.
(interval_generator_narrow): Mark it as non-static.
(interval_tree_iter_next, interval_tree_iter_narrow):
Delete functions. Inline their old bodies in the callers.
(interval_tree_iter_finish): Take the iter rather than
the whole tree. Adjust all callers.
(interval_generator_next): Move `running `assertion here from
`interval_tree_iter_next`.
* src/buffer.h: Adjust accordingly.
* src/itree.h (struct interval_tree): Remove fields `iter_running`,
`file`, and `line`, moved to `interval_generator`.
(interval_generator_narrow): Replace `interval_tree_iter_narrow`.
These bits really belong in the "workstack" used within
`interval_generator_next`, so move them there.
* src/itree.c (nodeptr_and_flag): New type;
(struct interval_stack): Use it.
(make_nav, nav_nodeptr, nav_flag): New functions.
(interval_tree_insert_gap, interval_tree_delete_gap): Adjust accordingly.

rather than inside the tree nodes.
(interval_stack_create, interval_stack_destroy, interval_stack_clear)
(interval_stack_ensure_space, interval_stack_push_flagged)
(interval_stack_push, interval_stack_pop): Move before first use.
* src/itree.h (struct interval_node): Remove `visited` field.
* src/pdumper.c (dump_interval_node): Adjust accordingly.
* src/alloc.c (mark_overlay): Add sanity check.
* src/buffer.c (next_overlay_change, previous_overlay_change):
Tweak code to keep the same vars for the bounds.
* src/itree.c (interval_tree_clear, interval_tree_insert)
(interval_tree_remove, interval_tree_insert_fix, interval_tree_remove_fix):
Adjust to the `color` -> `red` change.
(interval_tree_clear): Prefer `true/false` for booleans.
(interval_generator_create): Use an actual `interval_tree_order` value
rather than 0.
(interval_generator_next): Simplify a tiny bit. Add comment.
(interval_generator_narrow): Add sanity check.
* src/itree.h (struct interval_node): Replace `color` field with
boolean `red` field.
(enum interval_tree_order): Remove unused `ITREE_DEFLT_ORDER` value.
* src/pdumper.c (dump_interval_node): Adjust to the
`color` -> `red` change.
When starting an iteration, store __FILE__ and __LINE__ where this
happens in the interval_tree structure.
* src/buffer.h (buffer_overlay_iter_start): New macro adding __FILE
and __LINE__.
(buffer_overlay_iter_start1): Renamed from ..._start.
* src/itree.h (struct interval_tree): Add file and line info.
* src/itree.c: (interval_tree_contains, interval_tree_nodes,
interval_tree_insert_gap): Pass __FILE__ and __LINE__ to iter_start.
(interval_tree_iter_start): Record file and line info in tree.

* lisp/emacs-lisp/nadvice.el:
* lisp/emacs-lisp/cl-generic.el: Don't push to
package--builtin-versions "manually", because loaddefs-gen does
this correctly now.

i the same as `point`.

at the process.

(vc-git-pull-and-push): New function.

(c-electric-pair-inhibit-predicate): Use the value of c-open-string-opener to
