(cherry picked from commit 8a831d16)

xhprof removed their composer.json file, adding it to our composer.json file so we can still use composer to manage xhprof. Added an extra script to make sure the update is clean for git users.

Move JSON format bug fixes to new JSON2 format so existing clients will not fail. Add deprecation note for JSON format and use JSON2 in future proof code (angularjs/log importer).

refs #6013 #6012 make sure not to call console in case PHP is type CGI. In type CGI the argv should not be registered anyway unless maybe for instance register-argc-argv is enabled

Revert the date cache feature as it somehow (cause: unknown) causing pageviews to be lost when importing big log files.
This particular log file I'm testing on is for an intranet with thousands times the same IP address. Not sure if it's related, but the same IP address will have many visits at the same second, for different users (different _id=X in the piwik.php requests)

removed some outdated scripts that do no longer work anyway. use console and visitorgenerator plugin instead

Fixes #5807, refactor CronArchive class so it does not configure itself based on command line arguments. It now has properties that must be set. The core:archive command has been refactored to set these properties based on command line args.

Also includes:

  - bug fix to CronArchive::initLog method (config was modified after log instance created which negated it's effect)
  - misc/archive.php no longer uses Archive.php but executes the core:archive console command using Piwik\Console
  - remove forcelogtoscreen parameter (no longer necessary due to initLog changes)

Parameter passed to console should be --url=... instead of -- url=...

Changed JavaScript Tracking Code generation to use "//", instead of verifying whether the site is using "https", or not, and generating a corresponding URL.

"//" has been part of the RFC for well over 18 years. It has been confirmed to work in all major browsers (Firefox, Chrome, IE, Opera).
