Implement an emulated soft limit for file descriptors in addition to
the current reserved area, which effectively acts as a hard limit. The
setrlimit system call now simply updates the emulated limits as best
as possible - the hard limit is not allowed to move at all and just
returns EPERM if you try and change it.
This should stop reductions in the soft limit causing assertions when
valgrind tries to allocate descriptors from the reserved area.
