linux user patches

A series of patches for linux-user, specifically many FPU fixes in signal
handling code for sh4, mips, ppc and s390x (from Matt Turner), a madvise()
improvement (from me), and qemu header cleanups (from Peter Maydell).

---
v3: Fix build failure due to unknown MADV_COLLAPSE constant in madivise() patch
v2: Dropped the "ARM cortex-m55 program loading fix" and the FPU alpha patch
