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.

as it has moved kvm_check_features_against_host() after the

features not supported by the host, so this effectively made
kvm_check_features_against_host() impossible to fail.

This patch changes the call so we check for host feature support before
filtering the feature bits.

  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.

When we receive a file descriptor over a UNIX domain socket the
O_NONBLOCK flag is preserved.  Clear the O_NONBLOCK flag and rely on
QEMU file descriptor users like migration, SPICE, VNC, block layer, and
others to set non-blocking only when necessary.

This change ensures we don't accidentally expose O_NONBLOCK in the QMP
API.  QMP clients should not need to get the non-blocking state
"correct".

A recent real-world example was when libvirt passed a non-blocking TCP
socket for migration where we expected a blocking socket.  The source
QEMU produced a corrupted migration stream since its code did not cope
with non-blocking sockets.

There are several code paths in net_init_socket() depending on how the
socket is created: file descriptor passing, UDP multicast, TCP, or UDP.
Some of these support both listen and connect.

Not all code paths set the socket to non-blocking.  This patch addresses
the file descriptor passing and UDP cases which were missing
socket_set_nonblock(fd) calls.

I considered moving socket_set_nonblock(fd) to a central location but it
turns out the code paths are different enough to require non-blocking at
different places.
