[agraf: move hw/hw.h into existing ifdef]
Signed-off-by: Alexander Graf <agraf@suse.de>
The function is only used in misc_helper.c, so move it to that file.
This reduces the size of debug executables (compiled without optimization)
because they get unused code and data for each compilation which includes
cpu.h.
Executables with optimization don't change their size.
ebcdic2ascii is currently unused and could be removed (not done here).
The array ascii2ebcdic must be accessed with an unsigned index, therefore
(int)ascii[i] was replaced by (uint8_t)ascii[i]. The old code would have
failed for a signed char less than 0. The current code only converts
"QEMU" and spaces to EBCDIC, so there is no problem today.

This enables qemu -cpu help to return a list of supported CPU models
on s390 and also to query for cpu definitions in the monitor.
Initially only cpu model = host is returned. This needs to be reworked
into a full-fledged CPU model handling later on.
This change is needed to allow libvirt exploiters (like OpenStack)

qemu_chr_open_socket is split into two functions. All initialization
after creating the socket file handler is split away into the new
qemu_chr_open_socket_fd function.
chr->filename doesn't get filled from QemuOpts any more. Qemu gathers
the information using getsockname and getnameinfo instead. This way it
will also work correctly for file handles passed via file descriptor
passing.
Finally qmp_chardev_open_socket() is the actual qmp hotplug
implementation which basically just calls socket_listen or
socket_connect and the new qemu_chr_open_socket_fd function.
