7417ccfb0d py/formatfloat: Add ability to format doubles with exponents > 99.
For single prec, exponents never get larger than about 37.  For double
prec, exponents can be larger than 99 and need 3 bytes to format.  This
patch makes the number of bytes needed configurable.

Addresses issue #1772.

d3b1f0b627 py/runtime: mp_stack_ctrl_init() should be called immediately on startup.
Calling it from mp_init() is too late for some ports (like Unix), and leads
to incomplete stack frame being captured, with following GC issues. So, now
each port should call mp_stack_ctrl_init() on its own, ASAP after startup,
and taking special precautions so it really was called before stack variables
get allocated (because if such variable with a pointer is missed, it may lead
to over-collecting (typical symptom is segfaulting)).

6a804cbaba lib/utils/printf: Fix printf on release builds
When using newer glibc's the compiler automatically sets
_FORTIFY_SOURCE when building with -O1 and this causes
a special inlined version of printf to be declared which
then bypasses our version of printf.

7b05b1b225 py/bc: Update opcode format table now that MP_BC_NOT opcode is gone.
MP_BC_NOT was removed and the "not" operation made a proper unary
operator, and the opcode format table needs to be updated to reflect
this change (but actually the change is only cosmetic).

8f54c08691 py/inlineasm: Add ability to specify return type of asm_thumb funcs.
Supported return types are: object, bool, int, uint.

For example:

@micropython.asm_thumb
def foo(r0, r1) -> uint:
    add(r0, r0, r1)

a53af6c875 extmod/modurandom: Add some extra random functions.
Functions added are:
- randint
- randrange
- choice
- random
- uniform

They are enabled with configuration variable
MICROPY_PY_URANDOM_EXTRA_FUNCS, which is disabled by default.  It is
enabled for unix coverage build and stmhal.

ee1656e148 extmod/moduhashlib: Add support for SHA1 (based on axTLS).
SHA1 is used in a number of protocols and algorithm originated 5 years ago
or so, in other words, it's in "wide use", and only newer protocols use
SHA2.

The implementation depends on axTLS enabled. TODO: Make separate config
option specifically for sha1().

df4ce930e3 py/modmicropython: Add stack_use, heap_lock and heap_unlock functions.
micropython.stack_use() returns an integer being the number of bytes used
on the stack.

micropython.heap_lock() and heap_unlock() can be used to prevent the
memory manager from allocating anything on the heap.  Calls to these are
allowed to be nested.

42a6364a31 stmhal: Add support for building frozen files.
This allows FROZEN_DIR=some-directory to be specified on the make
command line, which will then add all of the files contained within
the indicated frozen directory as frozen files in the image.

There is no change in flash/ram usage if not using the feature.

This is especially useful on smaller MCUs (like the 401) which only
has 64K flash file system.

f8ba2eca80 builtin property: accept keyword arguments
this allows python code to use property(lambda:..., doc=...) idiom.

named versions for the fget, fset and fdel arguments are left out in the
interest of saving space; they are rarely used and easy to enable when
actually needed.

a test case is included.

5b3f0b7f39 py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.
The first argument to the type.make_new method is naturally a uPy type,
and all uses of this argument cast it directly to a pointer to a type
structure.  So it makes sense to just have it a pointer to a type from
the very beginning (and a const pointer at that).  This patch makes
such a change, and removes all unnecessary casting to/from mp_obj_t.

a0c97814df py: Change type of .make_new and .call args: mp_uint_t becomes size_t.
This patch changes the type signature of .make_new and .call object method
slots to use size_t for n_args and n_kw (was mp_uint_t.  Makes code more
efficient when mp_uint_t is larger than a machine word.  Doesn't affect
ports when size_t and mp_uint_t have the same size.
