[Qemu-devel] *-user fixes

[Ulrich Hecht]

Hi!

qemu-sigfpe.patch:
send SIGFPE in case of ARM FPA exceptions. No idea if this is 100%
correct, but it's good enough to convince the glibc test suite.

qemu-syscalls.patch:
some trivial syscall implementations; I only needed (and tested) madvise, 
but while I was there I noticed a number of other syscalls that can be 
implemented without much effort.

qemu-jobsignals.patch:
proper SIGTSTP/SIGCONT default handling; makes suspending/resuming my 
editor work.
