Secure ReadProperty decoding and BACnetActionCommand (#702)

* Refactored and secured BACnetActionCommand codec into bacaction.c module for command object and added to bacapp module encode/decode with define for enabling and pseudo application tag for internal use.

* Simplified bacapp_data_len() and moved into bacdcode module as bacnet_enclosed_data_len() function.

* Secured ReadProperty-REQUEST and -ACK decoding.

* Removed deprecated Keylist_Key() functions from usage.

* Removed pseudo application datatypes from bacapp_data_decode() which only uses primitive application tag encoded values.

* Defined INT_MAX when it is not already defined by compiler or libc.

* Deprecated bacapp_decode_application_data_len() and bacapp_decode_context_data_len() as they are no longer used in any code in the library.

* Added BACnetScale to bacapp module. Improved complex property value decoding. Refactored bacapp_decode_known_property() function.

* Refactored and improved the bacapp_snprintf() function for printing EPICS.

* Fixed Lighting Output WriteProperty to handle known property decoding.
