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 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).

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 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.)

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
the Makefile now uses $(PY_CORE_O).

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 4a93801c12 all: Update Makefiles and others to build with new ports/ dir layout.
Also renames "stmhal" to "stm32" in documentation and everywhere else.

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.
