pic16bit: Initial version of port to 16-bit PIC family. Reference MCU is dsPIC33J256GP506 with 256k ROM and 8k RAM, on the dsPIC DSC Starter Kit board. The REPL works, GC works, pyb module has LED and Switch objects. It passes some tests from the test suite (most it can't run because it doesn't have the Python features enabled).

all: Make netutils.h available to all ports by default. Generally, ports should inherit INC from py.mk, append to it, not overwrite it. TODO: Likely should do the same for other vars too.

Makefiles: Remove duplicate object files when linking. Scenario: module1 depends on some common file from lib/, so specifies it in its SRC_MOD, and the same situation with module2, then common file from lib/ eventually ends up listed twice in $(OBJ), which leads to link errors. Make is equipped to deal with such situation easily, quoting the manual: "The value of $^ omits duplicate prerequisites, while $+ retains them and preserves their order." So, just use $^ consistently in all link targets.
