5b31cc94b1 sccs: Manual changes 
For the uncommon items: Go through the tree and remove sccs tags that
didn't fit any nice pattern. If in the neighborhood, other SCM tags were
removed when they were detritis of long-ago CVS somehow in the early
mists of the project. Some adjacent copyrights stringswere removed (they
duplicated the copyright notices in the file). This also removed
non-standard formations of omission of SCCS tags (usually by adding an
extra #if 0 somewhere.

After this commit, a number of strings tagged with the 'what' @(#)
prefix remain, but they are primarily copyright notices.

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).
