acpi: initialize s4_val used in s4 shutdown

While investigating why a 32 bit Windows 2003 guest wasn't able to
successfully perform a shutdown /h, it was discovered that commit
afafe4bbe0cf7d3318e1ac7b40925561f86a6bd4 inadvertently dropped the
initialization of the s4_val used to handle s4 shutdown.
Initialize the value as before.

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.

acpi_table_add(): extract and reimplement internals

The new function acpi_table_install() installs any blob the caller passes
in. In the next patches this function will be promoted from helper role to
extern.

Reimplementing the logic should make it easier to understand. It also
removes a buffer overflow when

    has_header &&
    cumulative_file_size < ACPI_TABLE_HDR_SIZE - ACPI_TABLE_PFX_SIZE

(In that case the g_realloc() call in the read() loop used to shrink the
"acpi_tables" array, causing an out-of-bounds read access when copying the
header out of "acpi_tables".)

The new code isn't more daring alignment-wise than its predecessor:
"acpi_table_header" is packed, and the uint32_t fields are at offsets 6,
26, and 34.
