Hurd patches (fix compilation)

[Luca Weiss]

Hello,
I needed the following patches to build hurd commit 679b58fa.
All instances of "minor (", "major (", "makedev (" were prefixed with 
"gnu_dev_" because of errors like
../libfshelp/libfshelp.so: undefined reference to `minor'

And I added two includes:
* in pfinet/glue-include/linux/mm.h PAGE_SHIFT was not defined, but is in 
mach/vm_param.h
* in term/users.c e.g. SIGTSTP was not defined, but is in bits/signum-
generic.h which can be included with signal.h

Thanks,
Luca
