6c81f5a249 misc: add callback hooks and refactor pmc 
Callbacks for monitoring and performance measurement:
- Add new callback list type, with context
- Add callbacks for API, CLI, and barrier sync
- Modify node dispatch callback to pass plugin-specific context
- Modify perfmon plugin to keep PMC samples local to the plugin
- Include process nodes in dispatch callback
- Pass dispatch function return value to callback

Type: refactor

bef3619d25 Improve perfmon json table picker 
Built a tool to chew up https://download.01.org/perfmon/mapfile.csv,
and output a table in this format:

typedef struct {
  u8 model;
  u8 stepping;
  u8 has_stepping;
  char *filename;
} file_by_model_and_stepping_t;

static const file_by_model_and_stepping_t fms_table [] =
{
 /* model, stepping, stepping valid, file */
  { 0x2E, 0x0, 0, "NehalemEX_core_V2.json" },
  { 0x1E, 0x0, 0, "NehalemEP_core_V2.json" },
<snip>
  { 0x55, 0x5, 1, "cascadelakex_core_v1.00.json" },
  { 0x55, 0x6, 1, "cascadelakex_core_v1.00.json" },
  { 0x55, 0x7, 1, "cascadelakex_core_v1.00.json" },

5f1fd46573 Add x86_64 perfmon tables 
The license issue is resolved, so we can package the .json
files. Added to the vpp-dev package in .tar.xz form, which saves a lot
of space.

Updated the perfmon error log entry: tell folks where to find the
compressed tarball, and how to extract it.
