6515acca70 stm32/boards/*_af.csv: Make consistent use of JTMS, JTCK, SWDIO, SWCLK.
5-pin JTAG and 2-pin SWD are logically separate interfaces so encode them
in the AF tables as separate entries (separated by /, not -).

7d25a19220 docs/library/utime: Fix incorrect example with ticks_diff args order.
The parameter order in the example for ticks_diff was incorrect.  If it's
"too early" that means that scheduled time is greater than current time and
if it's "running late" then scheduled time would be less than current time.

64f11470be py/objgenerator: Remove unreachable code for STOP_ITERATION case.
This commit essentially reverts aa9dbb1b03
where this if-condition was added.  It seems that even when that commit
was made the code was never reached by any tests, nor reachable by
analysis (see below).  The same is true with the code as it currently
stands: no test triggers this if-condition, nor any uasyncio examples.
Analysing the flow of the program also shows that it's not reachable:

==START==
-> to trigger this if condition mp_execute_bytecode() must return
   MP_VM_RETURN_YIELD with *sp==MP_OBJ_STOP_ITERATION

   -> mp_execute_bytecode() can only return MP_VM_RETURN_YIELD from the
      MP_BC_YIELD_VALUE bytecode, which can happen in 2 ways:

      -> 1) from a "yield <x>" in bytecode, but <x> must always be a proper
         object, never MP_OBJ_STOP_ITERATION; ==END1==

      -> 2) via yield from, via mp_resume() which must return
         MP_VM_RETURN_YIELD with ret_value==MP_OBJ_STOP_ITERATION, which
         can happen in 3 ways:

         -> 1) it delegates to mp_obj_gen_resume(); go back to ==START==

         -> 2) it returns MP_VM_RETURN_YIELD directly but with a guard that
            ret_val!=MP_OBJ_STOP_ITERATION; ==END2==

         -> 3) it returns MP_VM_RETURN_YIELD with ret_val set from
            mp_call_method_n_kw(), but mp_call_method_n_kw() must return a
            proper object, never MP_OBJ_STOP_ITERATION; ==END3==

The above shows there is no way to trigger the if-condition and it can be
removed.

4e056d82cc esp8266/modules/webrepl_setup: Fix first-time enable of WebREPL.

"webrepl" in them that could be uncommented.

74fad3536b py/gc: In gc_realloc, convert pointer sanity checks to assertions.
These checks are assumed to be true in all cases where gc_realloc is

8e323b8fa8 py/qstr: Rewrite find_qstr to make manifest that it returns a valid ptr.
So long as the input qstr identifier is valid (below the maximum number of
qstrs) the function will always return a valid pointer.  This patch
eliminates the "return 0" dead-code.

84895f1a21 py/parsenum: Improve parsing of floating point numbers.
This patch improves parsing of floating point numbers by converting all the
digits (integer and fractional) together into a number 1 or greater, and
then applying the correct power of 10 at the very end.  In particular the
multiple "multiply by 0.1" operations to build a fraction are now combined
together and applied at the same time as the exponent, at the very end.

This helps to retain precision during parsing of floats, and also includes
a check that the number doesn't overflow during the parsing.  One benefit
is that a float will have the same value no matter where the decimal point
is located, eg 1.23 == 123e-2.

5e34a113ea py/runtime: Add MP_BINARY_OP_CONTAINS as reverse of MP_BINARY_OP_IN.
Before this patch MP_BINARY_OP_IN had two meanings: coming from bytecode it
meant that the args needed to be swapped, but coming from within the
runtime meant that the args were already in the correct order.  This lead
to some confusion in the code and comments stating how args were reversed.
It also lead to 2 bugs: 1) containment for a subclass of a native type
didn't work; 2) the expression "{True} in True" would illegally succeed and
return True.  In both of these cases it was because the args to
MP_BINARY_OP_IN ended up being reversed twice.

To fix these things this patch introduces MP_BINARY_OP_CONTAINS which
corresponds exactly to the __contains__ special method, and this is the
operator that built-in types should implement.  MP_BINARY_OP_IN is now only
emitted by the compiler and is converted to MP_BINARY_OP_CONTAINS by
swapping the arguments.

9783ac282e py/runtime: Simplify handling of containment binary operator.
In mp_binary_op, there is no need to explicitly check for type->getiter
being non-null and raising an exception because this is handled exactly by
mp_getiter().  So just call the latter unconditionally.

da154fdaf9 py: Add config option to disable multiple inheritance.
This patch introduces a new compile-time config option to disable multiple
inheritance at the Python level: MICROPY_MULTIPLE_INHERITANCE.  It is
enabled by default.

Disabling multiple inheritance eliminates a lot of recursion in the call
graph (which is important for some embedded systems), and can be used to
reduce code size for ports that are really constrained (by around 200 bytes
for Thumb2 archs).

With multiple inheritance disabled all tests in the test-suite pass except
those that explicitly test for multiple inheritance.

12ad64bc55 extmod/vfs_fat: Mount FatFS on creation so VFS methods can be used.
It's possible to use the methods (eg ilistdir) of a VFS FatFS object
without it being mounted in the VFS itself.  This previously worked but
only because FatFS was "mounting" the filesystem automatically when any
function (eg f_opendir) was called.  But it didn't work for ports that used
synchronisation objects (_FS_REENTRANT) because they are only initialised
via a call to f_mount.  So, call f_mount explicitly when creating a new
FatFS object so that everything is set up correctly.  Then also provide a
finaliser to do the f_umount call, but only if synchronisation objects are
enabled (since otherwise the f_umount call does nothing).

8d956c26d1 py/objstr: When constructing str from bytes, check for existing qstr.

1f1d5194d7 py/objstr: Make mp_obj_new_str_of_type check for existing interned qstr.
The function mp_obj_new_str_of_type is a general str object constructor
used in many places in the code to create either a str or bytes object.
When creating a str it should first check if the string data already exists
as an interned qstr, and if so then return the qstr object.  This patch
makes the function have such behaviour, which helps to reduce heap usage by
reusing existing interned data where possible.

The old behaviour of mp_obj_new_str_of_type (which didn't check for
existing interned data) is made available through the function
mp_obj_new_str_copy, but should only be used in very special cases.

One consequence of this patch is that the following expression is now True:

    'abc' is ' abc '.split()[0]

4601759bf5 py/objstr: Remove "make_qstr_if_not_already" arg from mp_obj_new_str.
This patch simplifies the str creation API to favour the common case of
creating a str object that is not forced to be interned.  To force
interning of a new str the new mp_obj_new_str_via_qstr function is added,
and should only be used if warranted.

Apart from simplifying the mp_obj_new_str function (and making it have the
same signature as mp_obj_new_bytes), this patch also reduces code size by a
bit (-16 bytes for bare-arm and roughly -40 bytes on the bare-metal archs).
