Paul Sokolovsky 429e3f077e unix: Make -v dump memory info at exit.
Also, move bytecode dumps to -v -v, because they're too verbose for just -v.

Damien George 1084b0f9c2 py: Store bytecode arg names in bytecode (were in own array).
This saves a lot of RAM for 2 reasons:

1. For functions that don't have default values, var args or var kw
args (which is a large number of functions in the general case), the
mp_obj_fun_bc_t type now fits in 1 GC block (previously needed 2 because
of the extra pointer to point to the arg_names array).  So this saves 16
bytes per function (32 bytes on 64-bit machines).

2. Combining separate memory regions generally saves RAM because the
unused bytes at the end of the GC block are saved for 1 of the blocks
(since that block doesn't exist on its own anymore).  So generally this
saves 8 bytes per function.

Tested by importing lots of modules:

- 64-bit Linux gave about an 8% RAM saving for 86k of used RAM.
- pyboard gave about a 6% RAM saving for 31k of used RAM.

Damien George 564963a170 py: Fix debug-printing of bytecode line numbers.
Also move the raw bytecode printing code from emitglue to mp_bytecode_print.

Damien George b427d6ae86 py: Fix line number printing for file with 1 line.
With a file with 1 line (and an error on that line), used to show the
line as number 0.  Now shows it correctly as line number 1.

But, when line numbers are disabled, it now prints line number 1 for any
line that has an error (instead of 0 as previously).  This might end up
being confusing, but requires extra RAM and/or hack logic to make it
print something special in the case of no line numbers.

Damien George 3c658a4e75 py: Fix bug where GC collected native/viper/asm function data.
Because (for Thumb) a function pointer has the LSB set, pointers to
dynamic functions in RAM (eg native, viper or asm functions) were not
being traced by the GC.  This patch is a comprehensive fix for this.

Addresses issue #820.

Damien George 2ac4af6946 py: Allow viper to have type annotations.
Viper functions can now be annotated with the type of their arguments
and return value.  Eg:

@micropython.viper
def f(x:int) -> int:
    return x + 1

Damien George 40f3c02682 Rename machine_(u)int_t to mp_(u)int_t.

Paul Sokolovsky 59c675a64c py: Include mpconfig.h before all other includes.
It defines types used by all other headers.

Fixes #691.

Damien George f0778a7ccb py: Implement default keyword only args.
Should finish addressing issue #524.

Damien George 915197a8f9 py: Remove emit_glue init and deinit. Needed only for debugging.
Debugging output for emit_glue now simplified so that the init and
deinit functions are no longer needed.

Damien George ccc85ea0da py: Combine native emitters to 1 glue function; distinguish viper.
This patch simplifies the glue between native emitter and runtime,
and handles viper code like inline assember: return values are
converted to Python objects.

Fixes issue #531.

Damien George 3417bc2f25 py: Rename byte_code to bytecode everywhere.
bytecode is the more widely used.  See issue #590.

Paul Sokolovsky 6b344d7816 py, unix: Add -v option, print bytecode dump if used.
This will work if MICROPY_DEBUG_PRINTERS is defined, which is only for
unix/windows ports. This makes it convenient to user uPy normally, but
easily get bytecode dump on the spot if needed, without constant recompiles
back and forth.

TODO: Add more useful debug output, adjust verbosity level on which
specifically bytecode dump happens.

Damien George 04b9147e15 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/.

Damien George 2827d62e8b py: Implement keyword-only args.
Implements 'def f(*, a)' and 'def f(*a, b)', but not default
keyword-only args, eg 'def f(*, a=1)'.

Partially addresses issue #524.

Damien George 3558f62fb5 py: Making closures now passes pointer to stack, not a tuple for vars.
Closed over variables are now passed on the stack, instead of creating a
tuple and passing that.  This way memory for the closed over variables
can be allocated within the closure object itself.  See issue #510 for
background.

Damien George df8127a17e py: Remove unique_codes from emitglue.c. Replace with pointers.
Attempt to address issue #386.  unique_code_id's have been removed and
replaced with a pointer to the "raw code" information.  This pointer is
stored in the actual byte code (aligned, so the GC can trace it), so
that raw code (ie byte code, native code and inline assembler) is kept
only for as long as it is needed.  In memory it's now like a tree: the
outer module's byte code points directly to its children's raw code.  So
when the outer code gets freed, if there are no remaining functions that
need the raw code, then the children's code gets freed as well.

This is pretty much like CPython does it, except that CPython stores
indexes in the byte code rather than machine pointers.  These indices
index the per-function constant table in order to find the relevant
code.

Damien George 69b89d21b2 py: Change compile order for default positional and keyword args.
This simplifies the compiler a little, since now it can do 1 pass over
a function declaration, to determine default arguments.  I would have
done this originally, but CPython 3.3 somehow had the default keyword
args compiled before the default position args (even though they appear
in the other order in the text of the script), and I thought it was
important to have the same order of execution when evaluating default
arguments.  CPython 3.4 has changed the order to the more obvious one,
so we can also change.

Damien George cdd96dff2c py: Implement more features in native emitter.
On x64, native emitter now passes 70 of the tests.

Damien George e337f1ef5e py: Towards default keyword arguments.
These are default arguments after a bare *.

Damien George d17926db71 Rename rt_* to mp_*.
Mostly just a global search and replace.  Except rt_is_true which
becomes mp_obj_is_true.

Still would like to tidy up some of the names, but this will do for now.

Damien George d1e443d0bc py: Free unique_code slot for outer module.
Partly (very partly!) addresses issue #386.  Most importantly, at the
REPL command line, each invocation does not now lead to increased memory
usage (unless you define a function/lambda).

Damien George 440f041525 py: Fix bugs with debugging output.
show_bc now decodes the prelude correctly.  Moved WRITE_FILE stuff from
runtime.c to emitglue.c.

Addresses issue #385.
