function webform_node_update_access in Webform 7.4

Menu access callback. Ensure a sure has access to update a webform node.

Unlike webform_results_access and webform_results_clear_access, access is completely overridden by the any implementation of hook_webform_update_access.

If hook_webform_update_access is implemented by one or more other modules, the results must be unanimously TRUE for access to be granted; otherwise it is denied if even one implementation returns FALSE, regardless of node_access and the 'edit webform components' permission. This allows implementors complete flexibility.

hook_webform_update_access should return TRUE if access should absolutely be granted, FALSE if it should absolutely be denied, or NULL if node_access and 'edit webform components' permission should determine access.
