* Added a MS/TP zero-config (automatically choose an unused MAC address) using an algorithm that starts with MAC=64 and waits for a random number of PFM (minimum of 8 plus modulo 64) before attempting to choose a MAC sequentially from 64..127. The confirmation uses a 128-bit UUID with the MSTP Test Request frame. The modifications are in src/bacnet/datalink/mstp.c and src/bacnet/datalink/dlmstp.c modules enabling any device to use zero-config if enabled. A working demonstration is in the ports/stm32f4xx for the NUCLEO board. Complete unit testing is included. Options include lurking forever (wait for a router or another master node before joining) or lurking for a minimum time (enables self forming automatic MAC addressing device nodes).
* Added basic Calendar object, unit tests, and integration with example device object.
* Added basic Time Value object, unit tests, and integration with example device object.

Fixed CMakeLists.txt: to exclude h_routed_npdu.c when BAC_ROUTING=OFF
When calling cmake with -DBAC_ROUTING=OFF,
basic/object/gateway/gw_device.c is correctly excluded from the build.
It does contain however the definition for the functions
Routed_Device_GetNext and Routed_Device_Is_Valid_Network, both of which
are called in the routed_apdu_handler function of basic/npdu/h_routed_npdu.c.
This is fine during compilation since these functions' prototypes are
declared in basic/object/device.h but linking will fail.
Thus, make the compilation of h_routed_npdu.c conditional depending on
the value of BAC_ROUTING.

* Fixed BACNET_STACK_EXPORT macro to Analog_Output_Read_Property function
Added the call to this macro so that Analog_Output_Read_Property is
properly exported as a global symbol when the library is compiled with
-DBUILD_SHARED_LIBS=ON using cmake. This macro expands to
__declspec(dllexport) on Windows and __attribute__((visibility("default")))
on Linux. It is necessary when compiling with the -fvisibility-hidden flag.
