target-s390x: fix style

Before splitting op_helper.c and helper.c in the next patches,
fix style issues. No functional changes.

Replace also GCC specific FUNCTION with
standard func.

Don't init static variable (cpu_s390x_init:inited) with 0.

s390: Fix error handling and condition code of service call

Invalid sccb addresses will cause specification or addressing exception.
Lets add those checks. Furthermore, the good case (cc=0) was incorrect
for KVM, we did not set the CC at all. We now use return codes < 0...

s390: provide interface for service interrupt/introduce interrupt.c

This patch creates interrupt.c. The first user is a callback for hw/*
code to trigger an service interrupt for a given sccb value. Several
interrupt types for s390 are floating (can be delivered to all CPUs)....

s390: autodetect map private

By default qemu will use MAP_PRIVATE for guest pages. This will write
protect pages and thus break on s390 systems that dont support this feature.
Therefore qemu has a hack to always use MAP_SHARED for s390. But MAP_SHARED
has other problems (no dirty pages tracking, a lot more swap overhead etc.)...

s390: stop target cpu on sigp initial reset

We must not run the target cpu after an initial reset. This makes
system_reset more reliable for smp guests.
