DirectFB-1.0 uses at least two of the four added ioctls, and the two
others were added for completeness. This patch was validated with the
program vlock -all/-new.

This patch series adds support for some ioctls related to the Linux
frame-buffer/console. It was fully tested for the SH4 target and
partially tested for the x86_64 and ARM targets, this latter fails the
setleds tests (embedded within the first commit message) but it
seems the problem doesn't

Changes introduced in v2 and v3:
* Fix typos + thinko (AT_RANDOM is used for stack canary, not for
ASLR)
* AT_RANDOM points to 16 random bytes stored inside the user
stack.
* Add a small test program.

Similar thing is done with scratchbox2, but with LD_PRELOAD instead of
ptrace. LD_PRELOAD for all around the corners (static binaries etc) and
the slowdown is major. ptrace would make at least the former problem
go away.
