Those calls to barf_if_interaction_inhibited meant inhibit-interaction
was checked before the keyboard macro code had a chance to provide
input.
I am moving the check on inhibit-interaction to run after checking
executing-kbd-macro in the low-level input handling mechanism,
read_char.
This allows the keyboard macro is allowed to provide input even if
inhibit-interaction=t.

Two concrete, real-life use cases:
- Users write functions using keyboard macros and put them in hooks,
which happen to get invoked by packages which use inhibit-interaction.
Those functions don't actually require interaction, but because they
break, ultimately no code can use inhibit-interaction.
- I run tests in a batch Emacs, frequently using keyboard macros to
provide input. Sometimes a bug causes code to run which calls
read-char outside of a keyboard macro. I would like such read-char
calls to error (instead of hanging, which is what they do by default
in batch mode). If I bind inhibit-interaction=t, then read-char will
exit with an error, but my keyboard macros will also immediately
error.

Will fix in next patch.
