Sparse doesn't like several of the DPDK header files. This patch
works around it so we can get analysis when compiling DPDK.

Commit 73c85181d (netdev-linux: Read packet auxdata to obtain vlan_tid)
added #include <linux/if_packet.h> to this file, to get the definition
of PACKET_AUXDATA and some other definitions, but on RHEL 6.1 this
provoked compiler errors:
In file included from /usr/include/linux/rtnetlink.h:5,
from lib/netdev-linux.c:34:
/usr/include/linux/netlink.h:34: error: expected specifier-qualifier-list
before 'sa_family_t'
Since the old #includes worked everywhere, and this file already defined
its own versions of most of the new macros that it needed, this commit just
reverts the old #includes and adds the one macro definition it didn't
already have.
(RHEL 6.1 isn't necessarily the only platform where this is a problem, but
it's the first one for which we noticed the problem.)
This switches the definition of sockaddr_ll used from the Linux one, which
uses __be16 for sll_protocol, to the glibc one, which uses plain "unsigned
short int". This makes sparse complain (rightly), so this commit also
adds a sparse-specific header that uses ovs_be16 to prevent the warning.

The only tricky part here is that I'm throwing in annotations to allow
"sparse" to report unbalanced locking.

With this commit, the tree compiles clean with sparse commit 87f4a7fda3d
"Teach 'already_tokenized()' to use the stream name hash table" with patch
"evaluate: Allow sizeof(_Bool) to succeed" available at
http://permalink.gmane.org/gmane.comp.parsers.sparse/2461 applied, as long
as the "include/sparse" directory is included for use by sparse (only),

make CC="CHECK='sparse -I../include/sparse' cgcc"
