src/output.c: refactor virtual output related functions This commit moves the virtual output related functions into their own file at `src/output-virtual.c` with its own include file to reduce `include/labwc.h` bit by bit. Additionally, it removes the need to keep the `server->headless.pending_output_name` char array around by temporarily disconnecting the handler when creating a new virtual output. This allows to set the output name right in the `output_virtual_add()` call rather than to store the pending name until the new output event handler has been called. It also makes adding a virtual fallback output easier in a follow-up PR. 2024-03-07 00:22:51 +01:00			`/* SPDX-License-Identifier: GPL-2.0-only */`

Add optional headless fallback output This allows configuring a headless fallback output that is automatically created whenever there is no other output around. It is destroyed when a new output is discovered. It can be enabled by setting the environment variable LABWC_FALLBACK_OUTPUT to the desired output name. The feature benefits applications like wayvnc the most as there is always an output available to connect to.
