9d6f474ea4 py/objstr: Don't treat bytes as unicode in str.count.
`b'\xaa \xaa'.count(b'\xaa')` now (correctly) returns 2 instead of 1.

Fixes issue #9404.

25ff5b52d9 py/parse: Allow const types other than int to optimise as true/false.
Allows optimisation of cases like:

    import micropython
    _DEBUG = micropython.const(False)
    if _DEBUG:
        print('Debugging info')

Previously the 'if' statement was only optimised out if the type of the
const() argument was integer.

The change is implemented in a way that makes the compiler slightly smaller
(-16 bytes on PYBV11) but compilation will also be very slightly slower.

As a bonus, if const support is enabled then the compiler can now optimise
const truthy/falsey expressions of other types, like:

    while "something":
        pass

... unclear if that is useful, but perhaps it could be.

fb77be1506 py: Include filename in errors from loading/saving files via "open".
This improves error messages in mpy-cross:
- When loading a .py file that doesn't exist (or can't be opened) it now
  includes the filename in the OSError.
- When saving a .mpy file that can't be opened it now raises an exception
  (prior, it would silently fail), and includes the filename in the
  OSError.

This matches class `__dict__`, and is similarly gated on
MICROPY_CPYTHON_COMPAT. Unlike class though, because modules's globals are
actually dict instances, the result is a mutable dictionary.

d94141e147 py/persistentcode: Introduce .mpy sub-version.
The intent is to allow us to make breaking changes to the native ABI (e.g.
changes to dynruntime.h) without needing the bytecode version to increment.

With this commit the two bits previously used for the feature flags (but
now unused as of .mpy version 6) encode a sub-version.  A bytecode-only
.mpy file can be loaded as long as MPY_VERSION matches, but a native .mpy
(i.e. one with an arch set) must also match MPY_SUB_VERSION.  This allows 3
additional updates to the native ABI per bytecode revision.

The sub-version is set to 1 because the previous commits that changed the
layout of mp_obj_type_t have changed the native ABI.

b41aaaa8a9 py/obj: Optimise code size and performance for make_new as a slot.
The check for make_new (i.e. used to determine something's type) is now
more complicated due to the slot access.  This commit changes the inlining
of a few frequently-used helpers to overall improve code size and

94beeabd2e py/obj: Convert make_new into a mp_obj_type_t slot.
Instead of being an explicit field, it's now a slot like all the other
methods.

This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.

6da41b5900 py/obj: Merge getiter and iternext mp_obj_type_t slots.
The goal here is to remove a slot (making way to turn make_new into a slot)
as well as reduce code size by the ~40 references to mp_identity_getiter
and mp_stream_unbuffered_iter.

This introduces two new type flags:
- MP_TYPE_FLAG_ITER_IS_ITERNEXT: This means that the "iter" slot in the
  type is "iternext", and should use the identity getiter.
- MP_TYPE_FLAG_ITER_IS_CUSTOM: This means that the "iter" slot is a pointer
  to a mp_getiter_iternext_custom_t instance, which then defines both
  getiter and iternext.

And a third flag that is the OR of both, MP_TYPE_FLAG_ITER_IS_STREAM: This
means that the type should use the identity getiter, and
mp_stream_unbuffered_iter as iternext.

Finally, MP_TYPE_FLAG_ITER_IS_GETITER is defined as a no-op flag to give
the default case where "iter" is "getiter".

3ac8b5851e py/obj: Add slot-index mp_obj_type_t representation.
The existings mp_obj_type_t uses a sparse representation for slots for the
capability methods of the type (eg print, make_new).  This commit adds a
compact slot-index representation.  The basic idea is that where the
mp_obj_type_t struct used to have 12 pointer fields, it now has 12 uint8_t
indices, and a variable-length array of pointers.  So in the best case (no
fields used) it saves 12x4-12=36 bytes (on a 32-bit machine) and in the
common case (three fields used) it saves 9x4-12=24 bytes.

Overall with all associated changes, this slot-index representation reduces
code size by 1000 to 3000 bytes on bare-metal ports.  Performance is
marginally better on a few tests (eg about 1% better on misc_pystone.py and
misc_raytrace.py on PYBv1.1), but overall marginally worse by a percent or
so.

See issue #7542 for further analysis and discussion.

fb2a57800a all: Simplify buffer protocol to just a "get buffer" callback.
The buffer protocol type only has a single member, and this existing layout
creates problems for the upcoming split/slot-index mp_obj_type_t layout
optimisations.

If we need to make the buffer protocol more sophisticated in the future
either we can rely on the mp_obj_type_t optimisations to just add
additional slots to mp_obj_type_t or re-visit the buffer protocol then.

This change is a no-op in terms of generated code.

makeversionhdr should be unforgiving
Recently(?) github started making it the default to only copy a single
branch (e.g., main) and NO TAGS into new forks.

This makes the step of the build process that determines the CircuitPython
version not work, because tags are expected to be present. When tags are
not present, the version number is only a git hash. The version number
ends up being 0.0.0.

This causes problems with libraries that check for CircuitPython version
to determine compatibility, among other things.

We'll do other things to improve the situation, such as document it.
But it'd also be good if the build stopped when this detectable condition
occurs.

Previously the desired output type was specified.  Now make the type part

This makes `mp_obj_new_str_type_from_vstr` a private function of objstr.c
(which is almost the only place where the output type isn't a compile-time
constant).
