Introduce new build option ENABLE_STACK_PROTECTOR. It enables compilation of all BL images with one of the GCC -fstack-protector-* options. A new platform function plat_get_stack_protector_canary() is introduced. It returns a value that is used to initialize the canary for stack corruption detection. Returning a random value will prevent an attacker from predicting the value and greatly increase the effectiveness of the protection. A message is printed at the ERROR level when a stack corruption is detected. To be effective, the global data must be stored at an address lower than the base of the stacks. Failure to do so would allow an attacker to overwrite the canary as part of an attack which would void the protection. FVP implementation of plat_get_stack_protector_canary is weak as there is no real source of entropy on the FVP. It therefore relies on a timer's value, which could be predictable.
