IN a bunch of comments we say 'under the terms of the GNU GPL', make
it clear this is GPLv2 (as LICENSE says).

Define FUSE_USE_VERSION < 35 to get old ioctl prototype
with int commands; define FUSE_USE_VERSION >= 35 to get
new ioctl prototype with unsigned int commands.
Fixes#463.
Instead of the Posix ioctl(2) command, Linux uses its own variant of ioctl()
in which the commands are requested as "unsigned long" and truncated to
32 bits by the fuse kernel module. Transmitting the commands to user space
file systems as "unsigned int" is a workaround for processing ioctl()
commands which do not fit into a signed int.
