60656eaea4 py: Define and use MP_OBJ_ITER_BUF_NSLOTS to get size of stack iter buf.
It improves readability of code and reduces the chance to make a mistake.

This patch also fixes a bug with nan-boxing builds by rounding up the
calculation of the new NSLOTS variable, giving the correct number of slots
(being 4) even if mp_obj_t is larger than the native machine size.

c88cfe165b py: Use size_t as len argument and return type of mp_get_index.
These values are used to compute memory addresses and so size_t is the
more appropriate type to use.

c61131380d windows: Make msvc project file support any version from VS2013 to VS2017
Instead of having the PlatformToolset property hardcoded to a specific
version just set it to the value of DefaultPlatformToolset: this gets
defined according to the commandline environment in which the build was
started.
Instead of just supporting VS2015 the project can now be built by any
version from VS2013 to VS2017 and normally future versions as well, without
quirks like VS asking whether you want to upgrade the project to the latest
version (as was the case when opening the project in VS2017) or not being
able to build at all (as was the case when opening the project in VS2013).

Also adjust the .gitignore file to ignore any artefacts from VS2017.

75589272ef all/Makefile: Remove -ansi from GCC flags, its ignored anyway.
The -ansi flag is used for C dialect selection and it is equivalent to -std=c90.
Because it goes right before -std=gnu99 it is ignored as for conflicting flags
GCC always uses the last one.

58f23def55 py/bc: Provide better error message for an unexpected keyword argument.
Now, passing a keyword argument that is not expected will correctly report
that fact.  If normal or detailed error messages are enabled then the name
of the unexpected argument will be reported.

This patch decreases the code size of bare-arm and stmhal by 12 bytes, and
cc3200 by 8 bytes.  Other ports (minimal, unix, esp8266) remain the same in
code size.  For terse error message configuration this is because the new
message is shorter than the old one.  For normal (and detailed) error
message configuration this is because the new error message already exists
in py/objnamedtuple.c so there's no extra space in ROM needed for the
string.

2e3fc77809 extmod/utime_mphal: Don't exit/enter the GIL in generic sleep functions.
GIL behaviour should be handled by the port.  And ports probably want to
define sleep_us so that it doesn't release the GIL, to improve timing
accuracy.

ebbaf7ee57 stmhal/pendsv: Disable interrupts during a thread switch.
We can actually handle interrupts during a thread switch (because we always
have a valid stack), but only if those interrupts don't access any of the
thread state (because the state may not correspond to the stack pointer).
So to be on the safe side we disable interrupts during the very short
period of the thread state+stack switch.

1a5c8d1053 py/vm: Don't release the GIL if the scheduler is locked.
The scheduler being locked general means we are running a scheduled
function, and switching to another thread violates that, so don't switch in
such a case (even though we technically could).

And if we are running a scheduled function then we want to finish it ASAP,
so we shouldn't switch to another thread.

Furthermore, ports with threading enabled will lock the scheduler during a
hard IRQ, and this patch to the VM will make sure that threads are not
switched during a hard IRQ (which would crash the VM).

9ee4641850 esp8266/machine_pin: Make pin.irq arguments positional.
All arguments to pin.irq are converted from keyword-only to positional, and
can still be specified by keyword so it's a backwards compatible change.

The default value for the "trigger" arg is changed from 0 (no trigger)
to rising+falling edge.

bf29fe2e13 py/objstr: Use better msg in bad implicit str/bytes conversion exception
Instead of always reporting some object cannot be implicitly be converted
to a 'str', even when it is a 'bytes' object, adjust the logic so that
when trying to convert str to bytes it is shown like that.
This will still report bad implicit conversion from e.g. 'int to bytes'
as 'int to str' but it will not result in the confusing
'can't convert 'str' object to str implicitly' anymore for calls like
b'somestring'.count('a').

5640e6dacd py: Provide mp_decode_uint_value to help optimise stack usage.
This has a noticeable improvement on x86-64 and Thumb2 archs, where stack
usage is reduced by 2 machine words in the VM.

71a3d6ec3b py: Reduce size of mp_code_state_t structure.
Instead of caching data that is constant (code_info, const_table and
n_state), store just a pointer to the underlying function object from which
this data can be derived.

This helps reduce stack usage for the case when the mp_code_state_t
structure is stored on the stack, as well as heap usage when it's stored
on the heap.

The downside is that the VM becomes a little more complex because it now
needs to derive the data from the underlying function object.  But this
doesn't impact the performance by much (if at all) because most of the
decoding of data is done outside the main opcode loop.  Measurements using
pystone show that little to no performance is lost.

This patch also fixes a nasty bug whereby the bytecode can be reclaimed by
the GC during execution.  With this patch there is always a pointer to the
function object held by the VM during execution, since it's stored in the
mp_code_state_t structure.

7b7ff60f91 travis: Change an stmhal rule to build PYBV11 instead of default PYBV10.
This allows to test the PYBV11 target as well as the network drivers
without adding another rule.  It also removes the need to use -B,
side-stepping the issue of whether or not -B works with qstr auto
generation.
