[pulseaudio-discuss] [PATCH 09/17] alsa: Add pa_alsa_profile_set_create_ports()

Currently, card ports, device prototypes and profiles are all created
together in an "interleaved" manner. My goal is to split that process
so that first all ports are created, then all device prototypes are
created and finally all profiles are created. This patch is the first
major step in that refactoring: all ports are created in
pa_alsa_profile_set_create_ports() before any device prototypes or
profiles are created. Most of the code in device_port_alsa_init() is
moved to create_port().
