Log message:
devel/meson/build.mk: Change MESON_CROSS_BINARIES -> MESON_BINARIES.

Use this with native builds too, via --native-file, if enabled.  No
change to builds that don't opt into using MESON_BINARIES.

Usage:

MESON_BINARIES+=	foo bar
MESON_BINARY.foo=	${TOOLBASE}/libexec/foo
MESON_BINARY_KEY.bar=	${PREFIX}/bin/bar
MESON_BINARY.bar=	${TOOLBASE}/bin/bar

Assuming PREFIX=/usr/pkg and TOOLBASE=/home/dev/pkg, this will build
with the following [binaries] section in the meson --native-file or
--cross-file:

[binaries]
foo = '/home/dev/pkg/libexec/foo'
/usr/pkg/bin/bar = '/home/dev/pkg/libexec/bar'

Log message:
gtk3: fix -doc option

Noticed by Mayuresh

Log message:
x11/gtk3: Draft some PRINT_PLIST_AWK.

No functional change to package build -- only assistance for future
maintainers.

For some reason this skips libdata/gtk-3.0/im-multipress.conf.  Can't
figure out why after 2min of poking at it.

Log message:
x11/gtk3: Set PLIST.foo to `yes', not `true'.

Log message:
x11/gtk3: Make this cross-compile.

New option `doc' for documentation.  Default-on for native builds
(hence no change to native builds), default-off for cross-builds
because apparently building the documentation requires running the
new gtk3 code and I can't figure out how to circumvent that in a few
minutes of fiddling.

New option `introspection' for gobject-introspection support.
Default-on for native builds (hence no change to native builds),
default-off for cross-builds (to which gobject-introspection is
fundamentally hostile).

Log message:
*: recursive bump for pango requiring fontconfig 2.15

Log message:
*: recursive bump for default-on option of at-spi2-core

Log message:
gtk3: Restore the gtk3-atk-bridge option.

It no longer unconditionally depends on dbus without this, so it's now
possible to build without dbus again.
