[PATCH 0/5] git-gui: workaround deprecation of Tcl/TK 8.5 in macOS

["Carlo Marcelo Arenas Belón" <carenas@gmail.com>]

This series, add improvements to allow running `git-gui` in macOS, which is
stuck in an ancient version of Tcl/TK that is no longer supported by git.

Patches 1 and 2 are minor fixes that could also apply to maint, but the main
change is in Patch 3, which removes the long obsoleted "Git Gui" app that was
tied to the system provided Tcl/TK framework and that has been broken for a
while.

Patches 4 and 5 are needed to avoid the system framework and facilitate using
a third party provided package of Tcl/TK 8.6 instead, but the last patch also
protects against a conflict with the Xcode provided git that for some reason
includes a copy pf `git-gui--askpass` even if `git-gui` is missing.

Carlo Marcelo Arenas Belón (5):
  git-gui: remove uname_O in Makefile
  git-gui: fix dependency of GITGUI_MAIN on generator
  git-gui: retire Git Gui.app
  git-gui: honor TCLTK_PATH in git-gui--askpass
  git-gui: ensure own version of git-gui--askpass is used
