Introduce callback for logging
Introduce an API for custom log handler functions. This allows libfuse
applications to send messages to syslog(3) or other logging systems.
See include/fuse_log.h for details.
Convert libfuse from fprintf(stderr, ...) to log_fuse(level, ...). Most
messages are error messages with FUSE_LOG_ERR log level. There are also
some debug messages which now use the FUSE_LOG_DEBUG log level.
Note that lib/mount_util.c is used by both libfuse and fusermount3.
Since fusermount3 does not link against libfuse, we cannot call
fuse_log() from lib/mount_util.c. This file will continue to use
fprintf(stderr, ...) until someone figures out how to split it up.
