For builds where mp_uint_t is larger than size_t, it doesn't make
sense to use such a wide type for qstrs. There can only be as many
qstrs as there is address space on the machine, so size_t is the correct
type to use.
Saves about 3000 bytes of code size when building unix/ port with
MICROPY_OBJ_REPR_D.
This patch consolidates all global variables in py/ core into one place,
in a global structure. Root pointers are all located together to make
GC tracing easier and more efficient.
Blanket wide to all .c and .h files. Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.
Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
The autogenerated header files have been moved about, and an extra
include dir has been added, which means you can give a custom
BUILD=newbuilddir option to make, and everything "just works"
Also tidied up the way the different Makefiles build their include-
directory flags
