vhost: support indirect Tx descriptors

Indirect descriptors are usually supported by virtio-net devices,

When the virtio device sends a packet using indirect descriptors,
only one slot is used in the ring, even for large packets.

The main effect is to improve the 0% packet loss benchmark.
A PVP benchmark using Moongen (64 bytes) on the TE, and testpmd
(fwd io for host, macswap for VM) on DUT shows a +50% gain for
zero loss.

On the downside, micro-benchmark using testpmd txonly in VM and
rxonly on host shows a loss between 1 and 4%. But depending on
the needs, feature can be disabled at VM boot time by passing

 error: type of bit-field `[...]' is a GCC extension

Note: the standard does not require implementations to issue a diagnostic
message with these, and such errors do not occur with recent GCC or clang
versions. However, GCC 4.7 is still common and using the extension keyword
is easier than checking compiler version.

lib: use C99 syntax for zero-size arrays

Exported header files used by applications should allow the strictest
compiler flags. Language extensions used in many places must be explicitly
marked or removed to avoid warnings and compilation failures.

The extension keyword is used whenever the C99 syntax cannot do it.

This commit prevents the following errors:

 error: ISO C forbids zero-size array `[...]'
