Subject: [PATCH] Make inhibit-interaction work properly with keyboard macros

Previously, inhibit-interaction=t prevented keyboard macros from
running, even when those macros did not result in user interaction,
since it was checked before the keyboard macro code had a chance to
provide input.

Now, if there's a running keyboard macro which can provide input, that
keyboard macro is allowed to provide input even if
inhibit-interaction=t.  This is achieved by moving the check on
inhibit-interaction to run after checking executing-kbd-macro in the
low-level input handling mechanism, read_char.

inhibit-interaction also suppresses reading from stdin in batch mode,
so we also must add a check on inhibit-interaction to
read_minibuf_noninteractive, which again is only called after checking
executing-kbd-macro.

* src/keyboard.c (read_char): Add call to
barf_if_interaction_inhibited. (bug#67837)
* src/lread.c (Fread_char, Fread_event, Fread_char_exclusive): Remove
call to barf_if_interaction_inhibited.
* src/minibuf.c (Fread_from_minibuffer): Remove call to
barf_if_interaction_inhibited.
(read_minibuf_noninteractive): Add call to barf_if_interaction_inhibited.
