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).
