ethernet: fix DMAC check and skip unnecessary ones (VPP-1868)

Fix and optimize DMAC check in ethernet-input node to utilize NIC or
driver which support L3 DMAC-filtering mode so that DMAC check can be
bypassed safely for interfaces/sub-interfaces in L3 mode.
Checking of interface in L3-DMAC-filtering state to avoid DMAC check
require the following:
a) Fix interface driver init sequence for devices which supports L3
DMAC-filtering to indicate its capability and initialize interface
to L3 DMAC-filtering state.
b) Fix ethernet_set_flags() function and its associated callback
flags_change() functions registered by various drivers in interface
infra to provide proper L3 DMAC filtering status.
Maintain interface/sub-interface L3 config count so DMAC checks can be
bypassed if L3 forwarding is not setup on any main/sub-interfaces.

Type: fix
Ticket: VPP-1868

devices: fix issue of per_interface_next_index

Per interface, next hop graph node can be customized
with vnet_hw_interface_rx_redirect_to_node function,
but it doesn't work well for af-packet type interface.

In current implementation, with function
af_packet_set_interface_next_node invoked next hop graph
node index can be set to apif->per_interface_next_index,
but it's not set to next0 properly for packet processing
in af_packet_device_input_fn.

VPPAPIGEN: vppapigen replacement in Python PLY.

This is a version of the VPP API generator in Python PLY. It supports
the existing language, and has a plugin architecture for generators.
Currently C and JSON are supported.

- vl_api_version to option version = "major.minor.patch"
- enum support
- Added error checking and reporting
- import support (removed the C pre-processor)
- services (tying request/reply together)

option version = "1.0.0";

enum colours {
BLUE = 50,
define foo {
vl_api_colours_t colours;

service {
rpc foo returns foo_reply;
rpc foo_dump returns stream foo_details;
rpc want_stats returns want_stats_reply
events ip4_counters, ip6_counters;

Future planned features:
- unions
- bool, text
- array support (including length)
- proto3 output plugin
- Refactor C/C++ generator as a plugin
- Refactor Java generator as a plugin

Add extern to *_main global variable declarations in header files.

- Global variables declared in header files without
the use of the 'extern' keword will result in multiple
instances of the variable to be created by the compiler
-- one for each different source file in which the
the header file is included. This results in wasted
memory allocated in the BSS segments as well as
potentially introducing bugs in the application.

VPP-1001 - update AF Packet Driver to for modern kernels

1. Add VNET headers support for checksumming - required

2. Bypass QDISC on transmit - improves performance by ~ 5%.
Enabled only if the macro is detected - apparently not
present on archaic distributions.

This still does not solve all issues with TSO - it can be
fixed only by going to tpacket v3 and dynamic rx ring as
well as significant changes in the TX (sendmmsg?).

Use thread local storage for thread index

This patch deprecates stack-based thread identification,
Also removes requirement that thread stacks are adjacent.

Finally, possibly annoying for some folks, it renames
all occurences of cpu_index and cpu_number with thread
index. Using word "cpu" is misleading here as thread can
be migrated ti different CPU, and also it is not related
to linux cpu index.

VPP-635: CLI Memory leak with invalid parameter

In the CLI parsing, below is a common pattern:
/* Get a line of input. */
if (!unformat_user (input, unformat_line_input, line_input))
return 0;

while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT)
if (unformat (line_input, "x"))
x = 1;
return clib_error_return (0, "unknown input `%U'",
format_unformat_error, line_input);
unformat_free (line_input);

The 'else' returns if an unknown string is encountered. There a memory
leak because the 'unformat_free(line_input)' is not called. There is a
large number of instances of this pattern.

Replaced the previous pattern with:
/* Get a line of input. */
if (!unformat_user (input, unformat_line_input, line_input))
return 0;

while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT)
if (unformat (line_input, "x"))
x = 1;
error = clib_error_return (0, "unknown input `%U'",
format_unformat_error, line_input);
goto done:

/* ...Remaining code... */

unformat_free (line_input);
return error;

In multiple files, 'unformat_free (line_input);' was never called, so
there was a memory leak whether an invalid string was entered or not.

Also, there were multiple instance where:
error = clib_error_return (0, "unknown input `%U'",
format_unformat_error, line_input);
used 'input' as the last parameter instead of 'line_input'. The result
is that output did not contain the substring in error, instead just an
empty string. Fixed all of those as well.

There are a lot of file, and very mind numbing work, so tried to keep
it to a pattern to avoid mistakes.
