Feature: Allows "-" as filename for the `--log` option.

When (e.g. for debugging purpose) the rest server is invoked like

	sudo -u restic rest-server … --log /dev/stdout

it tries to open `/dev/stdout` (O_CREATE, O_WRITE, O_APPEND). This
operation fails, as in the above invocation, `/dev/stdout` is owned by
the caller (here: root) and only writable for the caller. Subprocesses
get just the filedescriptor. Using `/proc/self/fd/1` didn't work either,
for the same reasons.

feat: allow logging to stdout The --log option accepts "-" as filename. This prevents rest-server from opening the log file, it simply writes to the STDOUT stream provided by the caller. BREAKING in case use really used "-" to specify a file named "-" you'll need to update your rest-server invocation to use "./-". 2023-03-23 19:19:18 +01:00			Feature: Allows "-" as filename for the `--log` option.
