Add WP-CLI support to enable/disable tracing

[bobbingwide]

It would be nice if we could turn tracing on and off from the command line.

Proposed solution

One way of achieving this is to provide some WP-CLI commands.

[bobbingwide]

Additionally, we should support logging in the daily trace summary of requests invoked from the command line using a wp-cli .phar file.

Note: bw_trace_status_report() can be invoked before WordPress has fully initialised. This can lead to Notices being produced

Notice: Undefined index: wp_post_types in oik-bwtrace\includes\oik-actions.php on line 318
Notice: Undefined index: wp_taxonomies in oik-bwtrace\includes\oik-actions.php on line 319

The following lines need to cater for global variables not having been set.
$func( count( $GLOBALS['wp_post_types'] ), "Post types", false );
$func( count( $GLOBALS['wp_taxonomies'] ), "Taxonomies", false );

Commands to support in oik-bwtrace include:

Command	Args	assoc_args	Notes
status	detail		Displays status for each trace type, followed by trace record details
on	type	--file= --reset --limit=	Turns tracing on
off	type		Turns tracing off
detail			Just displays the trace record details

To be considered

Command	Args	assoc_args	Notes
info			Displays the same as the Information block
actions	tbc		Displays trace actions
summary	on/off		Enables / disables Daily trace summary processing
logs			Actions related to trace log output files
reset	type		Resets the trace file

where
type = browser | ajax | rest | cli

This work has been on hold for a while.
