Alternative workaround to macOS SIGABRT on exit?

On lyx-users Anders reports that the following does not trigger the
issue:

  command-sequence buffer-close-all; lyx-quit

This suggests the idea that we can just call buffer-close-all inside of
lyx-quit, as done in the attached patch.

Any thoughts?

I have no strong opinion at all on this, and am fine to keep the code as
is.

Subject: [PATCH] Alternative workaround for macOS SIGABRT on exit

Anders confirms [1] that the following works well:

  command-sequence buffer-close-all; lyx-quit

This commit just modifies LYX_QUIT to first call BUFFER_CLOSE_ALL on
macOS.
