extmod/extmod.mk: Separate out extmod file list from py.mk to extmod.mk. This separates extmod source files from `py.mk`. Previously, `py.mk` assumed that every consumer of the py/ directory also wanted to include extmod/. However, this is not the case. For example, building mpy-cross uses py/ but doesn't need extmod/. This commit moves all extmod-specific items from `py.mk` to `extmod.mk` and explicitly includes `extmod.mk` in ports that use it. Signed-off-by: David Lechner <david@pybricks.com>

qemu-arm: fully integrated test suite. This is primarily intended to provide testing of Thumb-specific code within Travis CI as well as if anyone else want to run it locally. As discussed in purposes. This is currently agains an emulated Cortex-M3 core, however in the near future it can extended to support M0, M0+ as well M4 (work in progress exists in sushihangover/qemu). It's probably true that most of the code base can be covered running uPy natively on a POSIX system, however we do have the tiny bit of assembly code. There may exist bugs related to endianness and type aliases, let alone potential standard library or compiler bugs or even architecture-specific optimisations. This could also incorporate lwIP (or other TCP/IP stack) integration as well as SDIO+FATFS drivers. The solution to inline the test cases was chose due to simplicity. It could alternatively be implemented in a number of different way (see #515), but this looked the simplest. Inclusion of tinytest was just to avoid writing boilerplate code for counting failed tests and other utility functions. Currently only a few functions are used, however this could be extended. Checking in the code instead of using submodule was a personal preference, but if people do want the pain of submodules, this can provided. This particular framework is also pretty good if one desires to run unit test on target. The approach with scripts being inlined is probably not quite suited for the size of memory an MCU has, but the tinytest itself should be good, if lower-level C code is to be unit tested.

ports/qemu-arm: Rework "test" target using upytesthelper. The way tinytest was used in qemu-arm test target is that it didn't test much. MicroPython tests are based on matching the test output against reference output, but qemu-arm's implementation didn't do that, it effectively tested just that there was no exception during test execution. "upytesthelper" wrapper was introduce to fix it, so switch test implementation to use it. This requires passing different CFLAGS when building the firmware, so split out test-related parts to Makefile.test.

py/modbuiltins: For round() builtin use nearbyint instead of round. The C nearbyint function has exactly the semantics that Python's round() requires, whereas C's round() requires extra steps to handle rounding of numbers half way between integers. So using nearbyint reduces code size and potentially eliminates any source of errors in the handling of half-way numbers. Also, bare-metal implementations of nearbyint can be more efficient than round, so further code size is saved (and efficiency improved). nearbyint is provided in the C99 standard so it should be available on all supported platforms.

qemu-arm: Rework to run bare-metal on boards with Cortex-M CPUs. Adds support for 3 Cortex-M boards, selectable via "BOARD" in the Makefile: - microbit, Cortex-M0 via nRF51822 - netduino2, Cortex-M3 via STM32F205 - mps2-an385, Cortex-M3 via FPGA netduino2 is the default board because it's supported by older qemu versions (down to at least 2.5.0).

qemu-arm: Add 'test' target to Makefile to run and verify test suite. Replaces RUN_TEST=1 definition; now "make test" in qemu-arm directory will run tests/basics/ and check that they all succeed. This patch also enables the test on Travis CI.

cortex-m3-qemu: refactor the port. Switch from CodeSourcery to ARM GCC and clean-up some stale files, also copy `main.c` and `mpconfigport.h` from bare-arm.

## `$(LD)` doesn't seem to like `--specs` for some reason, but we can just use `$(CC)` here.
qemu-arm: Add ldscript dependency in the final firmware.elf target. So that the target is rebuilt if the linker script changes.

all: Make use of $(TOP) variable in Makefiles, instead of "..". $(TOP) is defined in py/mkenv.mk and should be used to refer to the top level of this repository.
