The current syntax for functions in `app` and `pred` patterns
allows a shorthand (F ARGS) where the object being matched is
added as an extra last argument. This is nice for things like
(pred (< 5)) but sometimes the object needs to be at
another position.
Until now you had to use (pred (lambda (x) (memq x my-list)))
or (pred (pcase--flip memq my-list)) in those cases.
So, introduce a new shorthand where `_` can be used to indicate
where the object should be passed: (pred (memq _ my-list))

The obsolete lazy-loaded bytecode feature, enabled by
`byte-compile-dynamic`, slows down Lisp execution even when not in use
because every call to a bytecode function has to check that function
for laziness.
This change forces up-front loading of all lazy bytecode so that we
can remove all those checks. (Dynamically loaded doc strings are not
affected.)
There is no point in generating lazy bytecode any more so we stop
doing that; this simplifies the compiler. `byte-compile-dynamic` now
has no effect.
This is a fully compatible change; the few remaining users of
`byte-compile-dynamic` should not notice any difference.

lazy bytecode.
* src/bytecode.c (exec_byte_code): Remove lazy bytecode checks.

While we're hopefully all aware of the usual confusion between
the scroll operation moving the document or moving the viewport, Emacs
has its very own instance of that confusion where the
`mouse-wheel-down-event` variable is the one that (used to) hold
the value `wheel-up` and vice versa.
Thanks for Po Lu's commit 957b4f826a which not only fixed my change
but brought that confusion to my attention.
This patch doesn't fix the problem, but tries to fix the other places
in the code where we did not take it into account.
* doc/lispref/commands.texi (Misc Events): Mention the
wheel-up/down confusion.
* lisp/progmodes/flymake.el (flymake--mode-line-counter-map):
* lisp/completion-preview.el (completion-preview--mouse-map):
Fix wheel-up/down confusion.
* lisp/mwheel.el (mouse-wheel-down-event, mouse-wheel-up-event):
Fix docstrings.
* doc/lispref/hash.texi (Hash Access):
* src/fns.c (Fmaphash):
Make it clear what the function passed as argument can do. Until now
these rules were unwritten, and are still unenforced.
The `mouse-wheel-DIR-event` vars were introduced because under X11
we get different `mouse-N` events depending on the users' mouse and
those same events can be used for other things for other rodents, so we
can't unconditionally treat those events as mouse-wheel events.
But this does not apply to the `wheel-up/down/...` events.
So hard code them.
* lisp/mwheel.el (mwheel--is-dir-p): Always consider the `wheel-DIR` events.
(mouse-wheel--setup-bindings): Always bind the `wheel-DIR` events.
* lisp/completion-preview.el (completion-preview--mouse-map):
Unconditionally bind the `wheel-DIR` events.
* lisp/edmacro.el (edmacro-fix-menu-commands): Hard code the
`wheel-DIR` events as mouse events regardless of `mouse-wheel-*-event`s.
* lisp/progmodes/flymake.el (flymake--mode-line-counter-map):
Do nothing, because it's already been done in commit e5be6c7ae3.
* doc/lispref/commands.texi (Misc Events): Document the need to use
`wheel-up/down/left/right` unconditionally.
* doc/lispref/windows.texi (Buffer Display Action Alists):
Add 'post-command-select-window'.
* lisp/window.el (display-buffer): Add 'post-command-select-window'
to the docstring and handle at the end of function.
* lisp/emacs-lisp/shortdoc.el (hash-table): Remove hash-table-size entry.
* doc/lispref/hash.texi (Other Hash):
* src/fns.c (Fhash_table_size): Make it clear that hash-table-size is
probably not worth using.

In addition to naming the advice function `symbol@name', set
the 'name' property to NAME.

`ad-advice-remove' is already interactive, but it doesn't work with
new-style advice.
* lisp/emacs-lisp/nadvice.el (advice-remove): Make it

* doc/lispref/functions.texi (Advising Named Functions): Document that
'advice-remove' is now an interactive command.

Rather than blindly increase `max-lisp-eval-depth` when entering the
debugger or running `signal-hook-function`, use this new "reserve"
to keep track of how much we have grown the stack for "debugger"
purposes so that for example recursive calls to `signal-hook-function`
can't eat up the whole C stack.
* src/eval.c (max_ensure_room): Rewrite.
(restore_stack_limits): Move before `max_ensure_room`. Rewrite.
(call_debugger, signal_or_quit): Adjust calls accordingly.
Also grow `max-lisp-eval-depth` for `hander-bind` handlers.
(init_eval_once): Don't initialize `max_lisp_eval_depth` here.
(syms_of_eval): Initialize it here instead.
Add new var `lisp-eval-depth-reserve`.
* doc/lispref/eval.texi (Eval): Add `lisp-eval-depth-reserve`.
AFAIK, this provides the same semantics as Common Lisp's `handler-bind`,
modulo the differences about how error objects and conditions are
represented.
* lisp/subr.el (handler-bind): New macro.
* src/eval.c (pop_handler): New function.
(Fhandler_Bind_1): New function.
(signal_or_quit): Handle new handlertypes `HANDLER` and `SKIP_CONDITIONS`.
(find_handler_clause): Simplify.
(syms_of_eval): Defsubr `Fhandler_bind_1`.
* doc/lispref/control.texi (Handling Errors): Add `handler-bind`.
* test/src/eval-tests.el (eval-tests--handler-bind): New test.
* lisp/emacs-lisp/lisp-mode.el (lisp-font-lock-keywords):
Move 'handler-bind' from CL-only to generic Lisp.
(handler-bind): Remove indentation setting, it now lives in the macro
definition.
