[Xu, HuilongX]

Tested-by: huilong xu <huilongx.xu at intel.com>
Run two unit case, are all passed.
Test environment:
OS: Linux ub12 3.13.0-32-generic #57~precise1-Ubuntu SMP Tue Jul 15 03:51:20 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
Gcc: gcc version 4.6.3 (Ubuntu/Linaro 4.6.3-1ubuntu5)
Package: dpdk.org next branch + patch
NIC: 09:00.0 Ethernet controller [0200]: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection [8086:10fb] (rev 01)
Target: x86_64-native-linuxapp-gcc

Test steps:
1. compile dpdk
   make install -j T=x86_64-native-linuxapp-gcc
2.install and bind dpdk
   modprobe uio
   insmod ./x86_64-native-linuxapp-gcc/kmod/igb_uio.ko
3.set hugepage
   mkdir -p /mnt/huge
   mount -t hugetlbfs nodev /mnt/huge
   echo 4096  >/sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages
4. run test app
   ./x86_64-native-linuxapp-gcc/app/test -c f -n 4 -- -i
5. exec unit case
   lpm_autotest
   table_autotest

> As next_hop field is increased now the maximum number of tbl8s is 2^24.
> A new rte_lpm_config structure is used so LPM library will allocate

> 
> Changed structures in LPM library:
> rte_lpm_tbl24_entry and rte_lpm_tbl8_entry to one structure
> rte_lpm_tbl_entry.
> 
> Added versioning symbols to functions and updated
> library and applications that have a dependency on LPM library.
