qemu-char: Print strerror message on failure
The only way for chardev drivers to communicate an error was to return a NULL pointer, which resulted in an error message that said _that_ something went wrong, but not _why_. This patch changes the interface to return 0/-errno and updates qemu_chr_open_opts to use strerror to display a more helpful error message.
