Breaking: #82893 - Remove global variable PARSETIME_START 

See forge#82893

Description 

The global variable $GLOBALS['PARSETIME_START'] can be removed, as it has been superseded by $GLOBALS['TYPO3_MISC']['microtime_start'] for a long time already.

Impact 

The variable is not available any more. If it is used it must be replaced (see Migration).

Affected Installations 

Installations that use the global variable $GLOBALS['PARSETIME_START'].

Migration 

Use round($GLOBALS['TYPO3_MISC']['microtime_start'] * 1000) if you need the same value as $GLOBALS['PARSETIME_START'] previously contained.
