Issue #1154382 by Berdir, barraponto, acouch, swentel, LoMo, DamienMcKenna, chx: Fixed View mode no longer can be changed.

- Patch #884948 by David_Rothstein: the wrong  parameter is sometimes passed in to hook_node_load().

- Patch #920614 by agentrickard, chx, Damien Tournoud: unpublished content visible when a Node Access module is enabled.

- Patch #502190 by jhodgdon, stella, sun: hook implementation headers out of compliance with standards.

Roll-back of #595084; type-hinting parameters at stdClass makes it so you can't ever pass in another type of class.

#309007 by moshe weitzman, agentrickard, and mcarbone: Add hook_node_access_records_alter() and hook_node_grants_alter() to allow complex interactions between two or more node access modules.
