Calling flush() when output buffering is enabled causes output to be
duplicated. Besides phpBB enabling output buffering for gzip compression,
output buffering may be enabled externally to phpBB via output_handler
or output_buffering directives in php.ini.
Use ob_get_level to determine whether output buffering is active and
call ob_flush in that case.
PHPBB3-10191
Output buffering may be enabled via various approaches, among them:
* output_buffering in php.ini;
* output_handler in php.ini enables output_buffering;
* ob_start call.
ob_get_level allows us to query php runtime for the actual output buffering
status.
