Those could probably be squashed with earlier patches, however I
couldn't easily identify them, test them or check if there are still
necessary on various platforms.

All chardev must implement chr_write(), but parallel and null chardev
both use null_chr_write(). Move it to the base class, so we don't need
to export the function when splitting the chardev in respective files.

The class kind is necessary to lookup the chardev name in
qmp_chardev_add() after calling qemu_chr_new_from_opts() and to set
the appropriate ChardevBackend (mainly to free the right
fields).
qemu_chr_new_from_opts() can be changed to use a non-qmp function
using the chardev class typename. Introduce qemu_chardev_add() to be
called from qemu_chr_new_from_opts() and remove the class chardev kind
field. Set the backend->type in the parse callback (when non-common
fields are added).

qemu_chr_new_from_opts() is modified to not need CharDriver backend[]
array, but uses instead objectified qmp_query_chardev_backends() and
char_get_class(). The alias field is moved outside in a ChardevAlias[],
similar to QDevAlias for devices.
"kind" and "parse" are moved to ChardevClass ("kind" is to be removed
next)

For some unclear reason to me, char-file does not have chr_free on
win32. Since we want to switch to instance finalizer instead of class
chr_free, we should be able to run the base WinChardev class finalizer
in any case. Use a boolean to skip free to ease the transition to
instance finalizer.

ldl_p has a signed return type so assigning it to uint64_t implicitly
sign-extends the value. This results in devices with min_access_size = 8
seeing unexpected values passed to their write handlers.
Example: guest performs a 32-bit write of 0x80000000 to an mmio region
and the handler receives 0xFFFFFFFF80000000 in its value argument.

Turn Chardev into Object.
qemu_chr_alloc() is replaced by the qemu_chardev_new() constructor. It
will call qemu_char_open() to open/intialize the chardev with the
ChardevCommon *backend settings.
The CharDriver::create() callback is turned into a ChardevClass::open()
which is called from the newly introduced qemu_chardev_open().
"chardev-gdb" and "chardev-hci" are internal chardev and aren't
creatable directly with -chardev. Use a new internal flag to disable
them. We may want to use TYPE_USER_CREATABLE interface instead, or
perhaps allow -chardev usage.
Although in general we keep typename and macros private, unless the type
is being used by some other file, in this patch, all types and common
helper macros for qemu-char.c are in char.h. This is to help transition
now (some types must be declared early, while some aren't shared) and
when splitting in several units. This is to be improved later.

vc_chr_write() is more appropriate than _puts() since no newline is
appended, even though it's not used only as a callback.
Keep "qemu_chr_parse" prefix, most chardev parse functions use this
prefix atm.

overwrite the console.c char driver.
