With gcc 4.1.0, I get a bunch of warnings about consts being lost in the
copy_user code. This patch fixes them by adding consts where necessary.

The upcoming patch series fixes bugs, compilation failures, and warnings,
and removes a dead file.

With newer libcs, the JB_* macros (which we shouldn't be using anyway,
probably) go away. This patch defines them if setjmp.h doesn't. It'd
be nice to have a real way to do this, as sysrq-t requires a way to
get registers from out-of-context threads, which we store in jmpbufs.

When UML opens a TUN/TAP device, the file descriptor could be copied into
later, long-lived threads, holding the device open even after the interface
is taken down, preventing it from being brought up again. This patch makes
these descriptors close-on-exec so that they disappear from helper proces
The network driver added an interface to the "opened" list when it was
configured, not when it was brought up, and removed it when it was taken
down. A sequence of ifconfig up, ifconfig down, ... caused it to be removed
multiple times from the list without being added in between, resulting in
a cr
It doesn't do anything but emit a warning, but there's a user population
that's used to adding 'debug' to the UML command line in order to gdb it.
With skas0 mode, that's not necessary, but these users need some indication
that 'debug' doesn't do what they want.

The process that UML uses to probe the host's ptrace capabilities can (rarely)
receive a SIGWINCH, confusing the parent. This fixes that by blocking
SIGWINCH.

We weren't making sure that we initialized the FP registers of new processes
to sane values.
This patch also moves some defines in the affected area closer to where they
are used.

A previous patch removed a file from the build without removing it from
