Instead of defining _GNU_SOURCE in each source file (and potentially
forgetting in some), tell the build system we use extensions and let it
define _GNU_SOURCE in config.h.
AM_PROG_MKDIR_P is deprecated since:
configure.ac:23: warning: The 'AM_PROG_MKDIR_P' macro is deprecated, and will soon be removed.
configure.ac:23: You should use the Autoconf-provided 'AC_PROG_MKDIR_P' macro instead,
configure.ac:23: and use '$(MKDIR_P)' instead of '$(mkdir_p)'in your Makefile.am files.
We are already using $(MKDIR_P) so we just need to call the right macro.
Udev is not meant to spawn long-running processes, and as of the next
udev version such processes will be killed.
If using systemd, device activation can be used to get the same effect.
On Arch we have been disabling this rule for a long time, even though we
don't use systemd, as it was causing more problems than it was worth.
Replacing the name setting code in src/adapter.c.
Moving the adapter naming allows us to use the /etc/machine-info [1]
pretty hostname, as implemented by hostnamed [2] in systemd.
If /etc/machine-info is not present, the adapter name stored
on disk in /var/lib/bluetooth will be used. If no adapter name
has been set yet, the default from the main.conf will be used.
We don't currently number the name of hci0 if a pretty name is
available, but we should instead number it if it happens not
to be the default adapter. As we cannot be told when the default
adapter changes, we'll behave this way for now.
Note that when an adapter name is set automatically from
the pretty hostname, changing it through the D-Bus interface
will fail.
