The "word" referred to by BYTES_PER_WORD is actually the size of mp_obj_t
which is not always the same as the size of a pointer on the target
architecture. So rename this config value to better reflect what it
measures, and also prefix it with MP_.
For uses of BYTES_PER_WORD in setting the stack limit this has been
changed to sizeof(void *), because the stack usually grows with
machine-word sized values (eg an nlr_buf_t has many machine words in it).

This is to be consistent with the same change in the unix port,
4ab8bee82f7d095c10c624de93da12a7aa1af8fd.

Change mp_uint_t to size_t to match the mp_print_strn_t function prototype.
This fixes a compiler warning when mp_uint_t and size_t are not the same
size.

This is run with uncrustify 0.70.1, and black 19.10b0.

Selectable via the command line: -march=xtensawin.

Fixes #5059. Done in collaboration with Jim Mussared.

mp_compile no longer takes an emit_opt argument, rather this setting is now
provided by the global default_emit_opt variable.
Now, when -X emit=native is passed as a command-line option, the emitter
will be set for all compiled modules (included imports), not just the
top-level script.
In the future there could be a way to also set this variable from a script.
Fixes issue #4267.

Prints something like:

Header files that are considered internal to the py core and should not
normally be included directly are:
py/nlr.h - internal nlr configuration and declarations
py/bc0.h - contains bytecode macro definitions
py/runtime0.h - contains basic runtime enums
Instead, the top-level header files to include are one of:
py/obj.h - includes runtime0.h and defines everything to use the
mp_obj_t type
py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h,
and defines everything to use the general runtime support functions
Additional, specific headers (eg py/objlist.h) can be included if needed.

Also renames "stmhal" to "stm32" in documentation and everywhere else.

This is a fix for https://github.com/micropython/micropython/issues/2209:
by default a file created using open() uses text translation mode so writing
\n to it will result in the file having \r\n. This is obviously problematic
for binary .mpy files, so provide functions for setting the open mode
and use binary mode in mpy-cross' main().

.mpy files contain the name of the source file that they were compiled
from. This patch adds a way to change this name to an arbitrary string,
specified on the command line with the -s option. The default is to use
the full name of the input filename.
This new -s option is useful to strip off a leading directory name so
that mpy-tool.py can freeze packages.

This component allows to generate .mpy files (pre compiled bytecode)
which can be executed within any MicroPython runtime/VM.
