Li Weiwei 3e6ab82179 py/repl: Fix handling of unmatched brackets and unfinished quotes.
Before this patch:

    >>> print(')
    ... ')
    Traceback (most recent call last):
      File "<stdin>", line 1
    SyntaxError: invalid syntax

After this patch:

    >>> print(')
    Traceback (most recent call last):
      File "<stdin>", line 1
    SyntaxError: invalid syntax

This matches CPython and prevents getting stuck in REPL continuation when a
1-quote is unmatched.

Damien George 6046e68fe1 py/repl: Initialise q_last variable to prevent compiler warnings.
Some older compilers cannot deduce that q_last is always written to before
being read.

Damien George 7241d90272 py/repl: Use mp_load_method_protected to prevent leaking of exceptions.
This patch fixes the possibility of a crash of the REPL when tab-completing
an object which raises an exception when its attributes are accessed.

See issue #3729.

Damien George eb88803ac8 py/{modbuiltins,repl}: Start qstr probing from after empty qstr.
The list of qstrs starts with MP_QSTR_NULL followed by MP_QSTR_, and these
should never appear in dir() or REPL tab completion, so skip them.

Damien George 165aab12a3 py/repl: Generalise REPL autocomplete to use qstr probing.
This patch changes the way REPL autocomplete finds matches.  It now probes
the target object for all qstrs via mp_load_method_maybe to look for a
match with the given input string.  Similar to how the builtin dir()
function works, this new algorithm now find all methods and instances of
user-defined classes including attributes of their parent classes.  This
helps a lot at the REPL prompt for user-discovery and to autocomplete names
even for classes that are derived.

The downside is that this new algorithm is slower than the previous one,
and in particular will be slower the more qstrs there are in the system.
But because REPL autocomplete is primarily used in an interactive way it is
not that important to make it fast, as long as it is "fast enough" compared
to human reaction.

On a slow microcontroller (CPU running at 16MHz) the autocomplete time for
a list of 35 names in the outer namespace (pressing tab at a bare prompt)
takes about 160ms with this algorithm, compared to about 40ms for the
previous implementation (this time includes the actual printing of the
names as well).  This time of 160ms is very reasonable especially given the
new functionality of listing all the names.

This patch also decreases code size by:

   bare-arm:    +0
minimal x86:  -128
   unix x64:  -128
unix nanbox:  -224
      stm32:   -88

There were several different spellings of MicroPython present in comments,
when there should be only one.

Damien George 3ff16ff52e py: Declare constant data as properly constant.
Otherwise some compilers (eg without optimisation) will put this read-only
data in RAM instead of ROM.

Paul Sokolovsky d59c2e5e45 py/repl: If there're no better alternatives, try to complete "import".
Also do that only for the first word in a line. The idea is that when you
start up interpreter, high chance that you want to do an import. With this
patch, this can be achieved with "i<tab>".

pohmelie 81ebba7e02 py: add async/await/async for/async with syntax
They are sugar for marking function as generator, "yield from"
and pep492 python "semantically equivalents" respectively.

@dpgeorge was the original author of this patch, but @pohmelie made
changes to implement `async for` and `async with`.

Alex March 69d9e7d27d py/repl: Check for an identifier char after the keyword.

Damien George 999cedb90f py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR.
This allows the mp_obj_t type to be configured to something other than a
pointer-sized primitive type.

This patch also includes additional changes to allow the code to compile
when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of
mp_uint_t, and various casts.

Alex March bfb272b9e0 py/repl: Treat escaped quotes correctly in REPL continuation.
Escaped quotes are now recognised correctly in REPL when used
inside normal quotes.

Damien George 28596edf07 py/repl: Don't look inside strings for unmatched brackets/quotes.
When looking to see if the REPL input needs to be continued on the next
line, don't look inside strings for unmatched ()[]{} ''' or """.

Addresses issue #1387.

Damien George ef7dd8db2d py/repl: Fix case where shorter names are shadowed by longer names.
Previous to this patch, if "abcd" and "ab" were possible completions
to tab-completing "a", then tab would expand to "abcd" straight away
if this identifier appeared first in the dict.

Damien George a1a2c411b2 py, readline: Add tab autocompletion for REPL.
Can complete names in the global namespace, as well as a chain of
attributes, eg pyb.Pin.board.<tab> will give a list of all board pins.

Costs 700 bytes ROM on Thumb2 arch, but greatly increases usability of
REPL prompt.

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 97790455fe Improve REPL detecting when input needs to continue.
Full CPython compatibility with this requires actually parsing the
input so far collected, and if it fails parsing due to lack of tokens,
then continue collecting input.  It's not worth doing it this way.  Not
having compatibility at this level does not hurt the goals of Micro
Python.

Damien d99b05282d Change object representation from 1 big union to individual structs.
A big change.  Micro Python objects are allocated as individual structs
with the first element being a pointer to the type information (which
is itself an object).  This scheme follows CPython.  Much more flexible,
not necessarily slower, uses same heap memory, and can allocate objects
statically.

Also change name prefix, from py_ to mp_ (mp for Micro Python).
