Steve Karg 770be70688 Chore/bacnet-sc-unrelated-cleanup (#620) 
* Added required linux Ethernet library for ethernet build

* Added .obj to gitignore

* Fixed BACnet port for APPLE to use BSD in CMake

* Changed format in CMake to enable cleaner SC merge

* Added create-object and delete-object recipes in GCC Makefile

* Added datalink timer to all example OS apps

* Changed most microcontroller ports to use BACAPP_MINIMAL to specify which datatypes can be written.

* Fixed zephyr OS for BACnet/IP warning

* Fixed zephyr OS log to not require log_strdup

* Added writefile API to file object example

* Added API to device-client to make it more robust.

* Added API in network-port object for getting the ASCII object-name

* Added debug print with a timestamp option

* Added debug print with hex dump print

* Added API to network port object for activate and discard

* Added default define for debug with timestamp

* Added prototype in header for disabled debug printf.

* Added fifo peek ahead function to peek at more than one byte.

* Added get-mac value for network port that uses buffer rather than octetstring
