hw: include hw header files with full paths

Done with this script:

hw: include hw header files with full paths

Done with this script:

cd hw
for i in `find . -name '*.h' | sed 's/^..//'`; do
echo '\,^#.*include.*["<]'$i'[">], s,'$i',hw/&,'
done | sed -i -f - `find . -type f`

This is so that paths remain valid as files are moved.

Instead, files in hw/dataplane are referenced with the relative path.
We know they are not going to move to include/, and they are the only
include files that are in subdirectories _and_ move.

hw: move qdev-monitor.o to toplevel directory

qdev-monitor.c is the only "core qdev" file that is not used in
user-mode emulation, and it does not define anything that is used
by hardware models. Remove it from the hw/ directory and
remove hw/qdev-monitor.h from hw/qdev.h too; this requires
some files to have some new explicitly includes.

can result in
"qemu-system-s390x: hw/s390x/sclpconsole.c:60: receive_from_chr_layer:
Assertion `scon->iov' failed."

Lets make sure that the init process is finished, since the iov is
allocated after CHR_EVENT_OPENED by also checking for scon->iov.

Make all static TypeInfos const

Make all static TypeInfos const

Since 39bffca2030950ef6efe57c2fac8327a45ae1015 (qdev: register all
types natively through QEMU Object Model), TypeInfo as used in
the common, non-iterative pattern is no longer amended with information
and should therefore be const.

Fix the documented QOM examples:

sed -i 's/static TypeInfo/static const TypeInfo/g' include/qom/object.h

Since frequently the wrong examples are being copied by contributors of
new devices, fix all types in the tree:

sed -i 's/^static TypeInfo/static const TypeInfo/g' */*.c
sed -i 's/^static TypeInfo/static const TypeInfo/g' */*/*.c

This also avoids to piggy-back these changes onto real functional
changes or other refactorings.

janitor: do not rely on indirect inclusions of or from qemu-char.h

Various header files rely on qemu-char.h including qemu-config.h or
main-loop.h, but they really do not need qemu-char.h at all (particularly
interesting is the case of the block layer!). Clean this up, and also
add missing inclusions of qemu-char.h itself.

s390: sclp ascii console support

This code adds console support by implementing SCLP's ASCII Console
Data event. This is the same console as LPARs ASCII console or z/VMs
sysascii.

The console can be specified manually with something like
-chardev stdio,id=charconsole0 -device sclpconsole,chardev=charconsole0,id=console0

Newer kernels will autodetect that console and prefer that over virtio
console.

When data is received from the character layer it creates a service
interrupt to trigger a Read Event Data command from the guest that will
pick up the received character byte-stream.
When characters are echo'ed by the linux guest a Write Event Data occurs
which is forwarded by the Event Facility to the console that supports
a corresponding mask value.
Console resizing is not supported.
The character layer byte-stream is buffered using a fixed size iov
buffer.
