Add license header to (almost) all files. Blanket wide to all .c and .h files. Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

all: Add *FORMAT-OFF* in various places. This string is recognised by uncrustify, to disable formatting in the region marked by these comments. This is necessary in the qstrdef*.h files to prevent modification of the strings within the Q(...). In other places it is used to prevent excessive reformatting that would make the code less readable.

py: Add LOAD_SUPER_METHOD bytecode to allow heap-free super meth calls. This patch allows the following code to run without allocating on the heap: super().foo(...) Before this patch such a call would allocate a super object on the heap and then load the foo method and call it right away. The super object is only needed to perform the lookup of the method and not needed after that. This patch makes an optimisation to allocate the super object on the C stack and discard it right after use. Changes in code size due to this patch are: bare-arm: +128 minimal: +232 unix x64: +416 unix nanbox: +364 stmhal: +184 esp8266: +340 cc3200: +128

py: Combine 3 comprehension opcodes (list/dict/set) into 1. With the previous patch combining 3 emit functions into 1, it now makes sense to also combine the corresponding VM opcodes, which is what this patch does. This eliminates 2 opcodes which simplifies the VM and reduces code size, in bytes: bare-arm:44, minimal:64, unix(NDEBUG,x86-64):272, stmhal:92, esp8266:200. Profiling (with a simple script that creates many list/dict/set comprehensions) shows no measurable change in performance.

py: Split RAISE_VARARGS opcode into 3 separate ones. From the beginning of this project the RAISE_VARARGS opcode was named and implemented following CPython, where it has an argument (to the opcode) counting how many args the raise takes: raise # 0 args (re-raise previous exception) raise exc # 1 arg raise exc from exc2 # 2 args (chained raise) In the bytecode this operation therefore takes 2 bytes, one for RAISE_VARARGS and one for the number of args. This patch splits this opcode into 3, where each is now a single byte. This reduces bytecode size by 1 byte for each use of raise. Every byte counts! It also has the benefit of reducing code size (on all ports except nanbox).
