Damien George fa873ce67c minimal/mpconfigport.h: Disable features that are not needed.
Now that there are feature levels, and that this port uses
MICROPY_CONFIG_ROM_LEVEL_MINIMUM, it's easy to see what optional features
can be disabled.  And this commit disables them.

Jim Mussared c9c55032dc minimal/Makefile: Don't force a 32-bit build.
Word-size specific configuration is now done automatically, so it no longer
requires this to match the ARM configuration.

Also it's less common to have 32-bit compilation support installed, so this
will make it work "out of the box" for more people.

Jim Mussared 910e060f93 minimal/mpconfigport.h: Use MICROPY_CONFIG_ROM_LEVEL_MINIMUM.
Update minimal port to use the new "minimal" rom level config (this is a
no-op change, the binary is the same size and contains the exact same
symbols).

Damien George 2c5993c59e ports: Disable MICROPY_PY_ASSIGN_EXPR in bare-arm and minimal ports.
To keep these ports as minimal as possible.

Damien George 8e591d412a minimal: Make build more flexible and work as 64-bit build.
Changes are:
- string0 is no longer built when building for host as the target, because
  it'll be provided by the system libc and may in some cases clash with the
  system one (eg on OSX).
- mp_int_t/mp_uint_t are defined in terms of intptr_t/uintptr_t to support
  both 32-bit and 64-bit builds.
- Configuration values which are the default in py/mpconfig.h are removed
  from mpconfigport.h to make the configuration a bit more minimal, eg as
  a better starting point for new ports.

stijn 84fa3312cf all: Format code to add space after C++-style comment start.
Note: the uncrustify configuration is explicitly set to 'add' instead of
'force' in order not to alter the comments which use extra spaces after //
as a means of indenting text for clarity.

stijn 30840ebc99 all: Enable extra conversion warnings where applicable.
Add -Wdouble-promotion and -Wfloat-conversion for most ports to ban out
implicit floating point conversions, and add extra Travis builds using
MICROPY_FLOAT_IMPL_FLOAT to uncover warnings which weren't found
previously.  For the unix port -Wsign-comparison is added as well but only
there since only clang supports this but gcc doesn't.

Jim Mussared 073b9a5eb8 ports: Enable error text compression for various ports, but not all.
Enabled on: bare-arm, minimal, unix coverage/dev/minimal, stm32, esp32,
esp8266, cc3200, teensy, qemu-arm, nrf.  Not enabled on others to be able
to test the code when the feature is disabled (the default case).

Damien George f8fc78691d py/mpconfig.h: Enable MICROPY_MODULE_GETATTR by default.
To enable lazy loading of submodules (among other things), which is very
useful for MicroPython libraries that want to have optional subcomponents.

Disabled explicitly on minimal ports.

David Lechner 3b07736b6d unix,windows: Use STDIN_FILENO, STDOUT_FILENO macros where appropriate.
This replaces 0 and 1 with STDIN_FILENO and STDOUT_FILENO to make the
intention of the code clearer.

Damien George 3f39d18c2b all: Add *FORMAT-OFF* in various places.
This string is recognised by uncrustify, to disable formatting in the
region marked by these comments.  This is necessary in the qstrdef*.h files
to prevent modification of the strings within the Q(...).  In other places
it is used to prevent excessive reformatting that would make the code less
readable.

David Lechner e79424d672 ports: Allow overriding CROSS_COMPILE in a custom makefile.
Many ports already allow overriding CROSS_COMPILE.  This modifies the
remaining ports to allow it as well.

Damien George b45f9de809 bare-arm, minimal: Set CSUPEROPT=-Os to get minimal firmware size.
This option affects py/vm.c and py/gc.c and using -Os gets them compiling a
bit smaller, and small firmware is the aim of these two ports.  Also,
having these files compiled with -Os on these ports, and -O3 as the default
on other ports, gives a better understanding of code-size changes when
making changes to these files.

Damien George af20c2ead3 py: Add global default_emit_opt variable to make emit kind persistent.
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.

Damien George 999733b1fb minimal: Use soft float for CROSS=1 Cortex-M4 target.
When compiled with hard float the system should enable FP access when it
starts or else FP instructions lead to a fault.  But this minimal port does
not enable (or use) FP and so, to keep it minimal, switch to use soft
floating point.  (This became an issue due to the recent commit
34c04d2319 which saves/restores FP registers
in the NLR state.)

it saves 408 bytes on x86.

Damien George a36c700d9b minimal/Makefile: Explicitly include lib/utils/printf.c in build.
The bare-metal port needs it and it's no longer included by default since

Damien George 9df6451ec5 ports/{bare-arm,minimal}/Makefile: Only build with core source files.
These ports don't need anything from extmod so don't include those files
at all in the build.  This speeds up the build by about 10% when building
with a single core.

Damien George a3dc1b1957 all: Remove inclusion of internal py header files.
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.

Damien George 01dd7804b8 ports: Make new ports/ sub-directory and move all ports there.
This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
