In preparation for switching to vmstate for migration support, fix
the sizes of various GIC state fields. In particular, we replace all
the bitfields (which VMState can't deal with) with straightforward
uint8_t values which we do bit operations on. (The bitfields made
more sense when NCPU was set differently in different situations,
but we now always model at the architectural limit of 8.)

The Memory chardev driver was added because, as the Monitor's output
buffer was static, we needed a way to accumulate the output of an
HMP commmand when ran by human-monitor-command.
However, the Monitor's output buffer is now dynamic, so it's possible
for the human-monitor-command to use it instead of the Memory chardev
driver.
This commit does that change, but there are two important
observations about it:
1. We need a way to signal to the Monitor that it shouldn't call
chardev functions when flushing its output. This is done
by adding a new flag to the Monitor object called skip_flush
(which is set to true by qmp_human_monitor_command())
2. The current code has buffered semantics: QMP clients will
only see a command's output if it flushes its output with
a new-line character. This commit changes this to unbuffered,
which means that QMP clients will see a command's output
whenever the command prints anything.
I don't think this will matter in practice though, as I believe
all HMP commands print the new-line character anyway.

Commit f628926bb4 changed monitor_flush()
to retry on qemu_chr_fe_write() errors. However, the Monitor's output
buffer can keep growing while the retry is not issued and this can
cause the buffer to overflow.
To reproduce this issue, just start qemu and type on the Monitor:
(qemu) ?
This will cause an assertion to trig.
To fix this problem this commit makes the Monitor buffer dynamic,
which means that it can grow as much as needed.

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.

This fixes things like:

xen-mapcache: pass the right size argument to test_bits
xen-mapcache: replace last_address_index with a last_entry pointer
Compute the correct size for test_bits().
qemu_get_ram_ptr() and qemu_safe_ram_ptr() will call xen_map_cache()
with size is 0 if the requested address is in the RAM. Then
xen_map_cache() will pass the size 0 to test_bits() for checking if the
corresponding pfn was mapped in cache. But test_bits() will always
return 1 when size is 0 without any bit testing. Actually, for this
case, test_bits should check one bit. So this patch introduced a
__test_bit_size which is greater than 0 and a multiple of XC_PAGE_SIZE,
then test_bits can work correctly with __test_bit_size
>> XC_PAGE_SHIFT as its size.
