qemu-ga: ga_get_fd_handle(): abort if fd_counter overflows

Today we reset fd_counter if it wraps, but it's better to abort()
instead, as fd_counter should never reach INT64_MAX.

usb-redir: Fix crash on migration with no client connected

If no client is connected on the src side, then we won't receive a
parser during migrate, in this case usbredir_post_load() should be a nop,
rather then to try to derefefence the NULL dev->parser pointer.

usb-tablet: Don't claim wakeup capability for USB-2 version

Our ehci code does not implement wakeup support, so claiming support for

qemu-char: Call fe_claim / fe_release when not using qdev chr properties

chardev-frontends need to explictly check, increase and decrement the
avail_connections "property" of the chardev when they are not using a
qdev-chardev-property for the chardev.

This fixes things like:
qemu-kvm -chardev stdio,id=foo -device isa-serial,chardev=foo \
  -mon chardev=foo

Working, where they should fail. Most of the changes here are due to
old hardware emulation code which is using serial_hds directly rather then
a qdev-chardev-property.

change element type from "char" to "unsigned char" in ACPI table data

The data is binary, not textual.

Also, acpi_table_add() abuses the "char *f" pointer -- which normally
points to file names to load -- to poke into the table. Introduce "char
unsigned *table_start" for that purpose.
