Jason Wang 264986e2c8 tap: multiqueue support 
Recently, linux support multiqueue tap which could let userspace call TUNSETIFF
for a signle device many times to create multiple file descriptors as
independent queues. User could also enable/disabe a specific queue through
TUNSETQUEUE.

The patch adds the generic infrastructure to create multiqueue taps. To achieve
this a new parameter "queues" were introduced to specify how many queues were
expected to be created for tap by qemu itself. Alternatively, management could
also pass multiple pre-created tap file descriptors separated with ':' through a
new parameter fds like -netdev tap,id=hn0,fds="X:Y:..:Z". Multiple vhost file
descriptors could also be passed in this way.

Each TAPState were still associated to a tap fd, which mean multiple TAPStates
were created when user needs multiqueue taps. Since each TAPState contains one
NetClientState, with the multiqueue nic support, an N peers of NetClientState
were built up.

A new parameter, mq_required were introduce in tap_open() to create multiqueue
tap fds.

# 1) A primitive type such as 'u8', 'u16', 'bool', 'str', or 'double'.
# These types are mapped to the appropriate JSON type.
#
# 2) A legacy type in the form 'legacy<subtype>' where subtype is the
# legacy qdev typename. These types are always treated as strings.
#
# 3) A child type in the form 'child<subtype>' where subtype is a qdev

# paths--absolute and partial paths.
#
# Absolute paths are derived from the root object and can follow child<>
# or link<> properties. Since they can follow link<> properties, they
# can be arbitrarily long. Absolute paths look like absolute filenames
# and are prefixed with a leading slash.
#
# Partial paths look like relative filenames. They do not begin
# with a prefix. The matching rules for partial paths are subtle but
# designed to make specifying objects easy. At each level of the
# composition tree, the partial path is matched as an absolute path.
# The first match is not returned. At least two matches are searched
# for. A successful result is only returned if only one match is
# found. If more than one match is found, a flag is return to
# indicate that the match was ambiguous.
#
# @property: The property name to read
#
# Returns: The property value. The type depends on the property type. legacy<>
# properties are returned as #str. child<> and link<> properties are
# returns as #str pathnames. All integer property types (u8, u16, etc)
# are returned as #int.

#
# @paging: if true, do paging to get guest's memory mapping. This allows

# IMPORTANT: this option can make QEMU allocate several gigabytes

# malicious guest pretending to be large.
#
# Also, paging=true has the following limitations:

# 1. The guest may be in a catastrophic state or can have corrupted
