Let's force having the bash-completion dependency when we want to enable
the feature. Then clearly shows the feature state in the final setup
summary.
Otherwise the risk is that GIMP may not use the correct path on a given
system and a packager who wants this script to be installed may miss
that it is installed in the wrong directory.
(cherry picked from commit 88b4f29ce7)
In particular make it also work with the `gimp-console` and with all
symlink names.
Also rename the bash completion file using the full application version
so that it will be possible to install several such completion files
side by side.
This fixes:
> […]/gimp/etc/meson.build:31:39: ERROR: dependency.get_variable got unknown keyword arguments "define_variable"
This MR was years-old. Maybe this option got renamed since that time.
Also get rid of various old references to menurc and don't install it anymore to
etc/ (neither the new shortcutsrc as it doesn't look like it brings much value
to do so).
Add a default toolrc file, installed in the sysconf dir, with a
more minimalistic tool layout using groups, inspired by Photoshop
(not identical, though, don't kill me! :)
It must not be a boolean but a `feature` option, with `auto` by default.
`auto` value mean enabled for macOS and Win32, and disabled for other
cases. This default logics disappeared in the meson build.
Also the mypaint-brushes package is a mandatory dependency, which must
always be checked. Absence is fatale.
Finally properly set the MYPAINT_BRUSHES_DIR macro depending on the
proper relocatable case.
