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).
