From: Philippe Mathieu-Daudé <f4bug@amsat.org>

Apple's Git distribution actually carries a similar file which
annotates *.m:
https://github.com/apple-opensource/Git/blob/73/gitattributes

See comments in commit 29cf16db23 ("buildsys: Help git-diff
adding .gitattributes config file") for details.

[PULL 2/4] qemu/main-loop: Disable block backend global state assertion on Cocoa

[Philippe Mathieu-Daudé]

From: Philippe Mathieu-Daudé <f4bug@amsat.org>

Since commit 0439c5a462 ("block/block-backend.c: assertions for
block-backend") QEMU crashes when using Cocoa on Darwin hosts.

Example on macOS:

  $ qemu-system-i386
  Assertion failed: (qemu_in_main_thread()), function blk_all_next, file block-backend.c, line 552.
  Abort trap: 6

Looking with lldb:

  Assertion failed: (qemu_in_main_thread()), function blk_all_next, file block-backend.c, line 552.
  Process 76914 stopped
  * thread #1, queue = 'com.apple.main-thread', stop reason = hit program assert

As we are in passed release 7.0 hard freeze, disable the block
backend assertion which, while being valuable during development,
is not helpful to users. We'll restore this assertion immediately
once 7.0 is released and work on a fix.

[PULL 4/4] ui/console: Check console before emitting GL event

[Philippe Mathieu-Daudé]

From: Akihiko Odaki <akihiko.odaki@gmail.com>

Without this change, The GL output of a console overwrites the
other consoles and makes them unusable.

To explicitly reply here (too): I would like to rebase my patch (and 
subsequent PR) on this PR here.  I’d therefore like this PR to proceed 
(if possible).
