Fixes segfault on callable("string").

Addresses Issue #207.

STM port crashes without this re-init.  There should not be any state in
the core py/ code that relies on pre-initialised data.

Implement octal and hex escapes in strings.

Add Generic Feature Macros to mpconfigport

* Add some generic feature macros to mpconfigport
* Move pin and port definitions from usrsw.c to mpconfigport

Conflicts:
	stm/main.c

Addresses Issue #199.

Also fixes a bug in the for-in-range optimiser.

I hope to remove break and continue byte codes in the future and just
use jump (if possible).

Fix malformed makeqstrdata generated file when using python 2.7

f2d and d2f functions from libgcc does not work correctly, most likely
due to the ABI being incorrect.  libgcc disabled for now.

mpconfigport.h is now included by stm32f4xx.h so that all STM files have
access to these defines.

Remove hardcoded PLL_M value

Conflicts:
	py/objstr.c
	py/py.mk
	py/stream.c
	unix/main.c
	unix/socket.c

Can now have null bytes in strings.  Can define ROM qstrs per port using
qstrdefsport.h

* Add the option to pass OSC frequency on command line.

Note that splitting by explicit string is not implemented so far.

Also, support negative indexes.
