[OE-core] [RFC 00/14] add virtual/bluez

[Peter A. Bigot]

I'm a bit out of my comfort zone here but I needed to do a lot of this
for myself, so figured I'd see how close this is to being mergeable.

This series is a proposed fix for Yocto 5031, providing virtual/bluez to
select between bluez4 and bluez5.  The intent is to continue using
bluez4 as the default, but to allow distros to switch to bluez5 if the
packages they need support the new interface.

There are conflicts.

bluez-hcidump got integrated into bluez5, so there's now virtual build
and runtime support to select the right one.

gst-plugin-bluetooth was removed from bluez5 and AFAICT has no
replacement.

obexd also got integrated into bluez5.  That's harder, because it
crosses the oe-core/meta-oe boundary so the virtual selectors can't be
done solely on oe-core.  I'm proposing an in-recipe conditional on
PREFERRED_PROVIDER-virtual/bluez to select the correct provider for
gnome-bluetooth.

I get my bluez5 builds with the following settings:

PREFERRED_PROVIDER_virtual/bluez = "bluez5"
VIRTUAL-RUNTIME_bluez = "bluez5"
PREFERRED_PROVIDER_bluez-hcidump = "bluez5"
PNBLACKLIST[bluez-hcidump] = "superseded by bluez5"
PNBLACKLIST[gst-plugin-bluetooth] = "dropped from bluez5"
PNBLACKLIST[bluez4] = "superseded by bluez5"

If there's a way to infer the required blacklists from the setting for
virtual/bluez that'd probably be a better approach.

I'm aware that gstreamer1.0-plugins-bad doesn't currently support
bluez5, and I've noted that in the commit message (bluetooth support
will be silently disabled by configure).

There are other packages and other features that don't fully support
bluez5; for example I don't think the issue with headsets is fully
resolved.  I don't feel that this should block merging bluez5 support,
as not everybody who wants bluez5 is going to care about those missing
features, and bluez4 support remains available for those who do.

I've done what I can to make sure all recipes I touched build with both
bluez4 and bluez5 but can't test whether their bluetooth support is
complete.

There's a corresponding set of patches to meta-openembedded for
virtual/bluez support at:
