        src/lib/librumphijack: hijack.c

Log Message:
A simple dup2-enforced affine transformation isn't enough when
dealing with dup2() from a rump kernel fd to a host kernel fd.
Consider:

s1 = socket();
s2 = socket();
dup2(s2, 0);

Instead, maintain a real mapping table (and get on my knees and
pray i don't have to touch this hair-splitting code ever again).

Apparently bourne shell scripts from a rump kernel fs work now
(sh script.sh; ./script.sh doesn't work for obvious "IT'S THE WRONG
FS NAMESPACE" reasons).  No test regressions either, so I'm a
happy camper.
