557d128b68 Add client-side msg_name_and_crc -> msg_index table
vppapigen now generates per-message crcs. Verified that whitespace
and real changes in message A don't change the crc for message B, etc.

Fixed the sample and flowperpkt plugins to participate. Others need
the same treatment. They don't build due to python/java language binding
build issues.

To use the scheme:

Client connects as usual.

Then call: u32 vl_api_get_msg_index(char * name_and_crc)
name_and_crc is a string like: "flowperpkt_tx_interface_add_del_753301f3",
aka the message name with _%08x <expected crc> appended.

Try these vpp-api-test commands to play with it:

vat# dump_msg_api_table
     <snip>
 [366]: punt_reply_cca27fbe
 [367]: ipsec_spd_dump_5e9ae88e
 [368]: ipsec_spd_details_6f7821b0
 [369]: sample_macswap_enable_disable_0f2813e2
 [370]: sample_macswap_enable_disable_reply_476738e5
 [371]: flowperpkt_tx_interface_add_del_753301f3
 [372]: flowperpkt_tx_interface_add_del_reply_d47e6e0b

vat# get_msg_id sample_macswap_enable_disable_reply_476738e5
 'sample_macswap_enable_disable_reply_476738e5' has message index 370

vat# get_msg_id sample_macswap_enable_disable_reply_476738e3
 'sample_macswap_enable_disable_reply_476738e3' not found

CRCs may vary, etc.

vppapigen is used to build a set of JSON representations
of each API file from vpp-api/Makefile.am and that is in
turn used by each language binding (Java, Python, Lua).

370dde3e7e LoadBal: Use intrinsics and use protocol number
This patch modifies the load balancer hash table such that
it uses vector operations.

It also fixes the hash computation logic such that the port
is only looked-up for TCP and UDP.
Some additional work is still needed for other types of traffic.

f588f35d66 Test: Add test case for Load Balancer plugin
This adds a basic test for the four existing encap modes
for the load balancer plugin.
- ip4 over gre4
- ip4 over gre6
- ip6 over gre4
- ip6 over gre6

Apparently, scapy does not support GRE and IPv6 combinations.
Hence, those tests do send packets through VPP, but only
ip4 over gre4 output is actually parsed and verified.

d4bc9af55f Load Balancer: Use FIB 2.0
This patch fixes load balancer, which was not working
since FIB 2.0.

Two FIB DPO types are defined:
- One for IPv4 GRE
- One for IPv6 GRE

When an AS is created, the plugin automatically uses
the result from the FIB in order to transmit the packet.
Therefore, the packet does not need to visit ip-lookup twice.

The 'bypass' command was removed, as it is now done
automatically using this process.
