ca3333dd4a linux(4): Use Linux dev_t type for mknod syscalls dev argument 
As of version 2.6.0 of the Linux kernel, dev_t is a 32-bit unsigned integer
on all platforms. Prior the 2.6 kernel dev_t type was an unsigned short.
However, since the firs commit of the Linuxulator, mknod syscall get int dev
argument.
Also, there is some confusion here, while the kernel declares a dev_t type
as a 32-bit sized, the user-space dev_t type can be size of 64 bits, e.g.,
in the Glibc library.
To avoid confusion and to help porting of the Linuxulator to other platforms
use explicit l_dev_t for dev argument of mknod syscalls.

559b94a122 syscall.master: Fix comments 
Have more accruate comments. While #if, #else, etc are copied to the
header files, lines that don't start with # are not.  And #include files
are only output to sysinc (which winds up at the front of init_sysent.c
which seems a bit odd). This is all radically undocumented, and likely
has drifted somewhat from 4.4BSD and what other systems do (they've
drifted too, fwiw).

149afbf3ba Fix 64-bit syscall argument fetching in 32-bit Linux syscall handlers. 
The Linux32 system call argument fetcher places each argument (passed in
registers in the Linux x86 system call convention) into an entry in the
generic system call args array.  Each member of this array is 8 bytes
wide, so this approach is broken for system calls that take off_t
arguments.

Fix the problem by splitting l_loff_t arguments in the 32-bit system
call descriptions, the same as we do for FreeBSD32.  Change entry points
to handle this using the PAIR32TO64 macro.

Move linux_ftruncate64() into compat/linux.
