py: Make dict use a bit less RAM when iterating; properly del values.
...
Heap RAM was being allocated to print dicts and do some other types of
iterating. Now these iterations use 1 word of state on the stack.
Deleting elements from a dict was not allowing the value to be reclaimed
by the GC. This is now fixed.

stmhal: Change 64-bit arithmetic to 32-bit for SD card block addressing.
...
By measuring SD card addresses in blocks and not bytes, one can get away
with using 32-bit numbers.
This patch also uses proper atomic lock/unlock around SD card
read/write, adds SD.info() function, and gives error code for failed
read/writes.

py: Load strings as objects when compiling viper.
...
Eventually, viper wants to be able to use raw pointers to strings and
arrays for efficient access. But for now, let's just load strings as a
Python object so they can be used as normal. This will anyway be
compatible with eventual intended viper behaviour.

py: Fix definition of sys.maxsize with mpz changes.

9a21d2e070
py: Make mpz able to use 16 bits per digit; and 32 on 64-bit arch.
...
Previously, mpz was restricted to using at most 15 bits in each digit,
where a digit was a uint16_t.
With this patch, mpz can use all 16 bits in the uint16_t (improvement
to mpn_div was required). This gives small inprovements in speed and
RAM usage. It also yields savings in ROM code size because all of the
digit masking operations become no-ops.
Also, mpz can now use a uint32_t as the digit type, and hence use 32
bits per digit. This will give decent improvements in mpz speed on
64-bit machines.
Test for big integer division added.
