Jim Mussared 94beeabd2e py/obj: Convert make_new into a mp_obj_type_t slot.
Instead of being an explicit field, it's now a slot like all the other
methods.

This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.

Jim Mussared 662b9761b3 all: Make all mp_obj_type_t defs use MP_DEFINE_CONST_OBJ_TYPE.
In preparation for upcoming rework of mp_obj_type_t layout.

Jim Mussared 8a0ee5a5c0 py/objstr: Split mp_obj_str_from_vstr into bytes/str versions.
Previously the desired output type was specified.  Now make the type part
of the function name.  Because this function is used in a few places this
saves code size due to smaller call-site.

This makes `mp_obj_new_str_type_from_vstr` a private function of objstr.c
(which is almost the only place where the output type isn't a compile-time
constant).

This saves ~140 bytes on PYBV11.

Damien George efe23aca71 all: Remove third argument to MP_REGISTER_MODULE.
It's no longer needed because this macro is now processed after
preprocessing the source code via cpp (in the qstr extraction stage), which
means unused MP_REGISTER_MODULE's are filtered out by the preprocessor.

Jim Mussared 0e7bfc88c6 all: Use mp_obj_malloc everywhere it's applicable.
This replaces occurences of

    foo_t *foo = m_new_obj(foo_t);
    foo->base.type = &foo_type;

with

    foo_t *foo = mp_obj_malloc(foo_t, &foo_type);

Excludes any places where base is a sub-field or when new0/memset is used.

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.

Yonatan Goldschmidt e328b4593c extmod/moducryptolib: Refactor functions for clean interface with axTLS.
This will allow implementations other than axTLS.

This commit includes additions of checks and clarifications of exceptions
related to user input.

To make the interface cleaner, I've disallowed switching from encrypt to
decrypt in the same object, as this is not always possible with other
crypto libraries (not all libraries have AES_convert_key like axTLS).

enable them.

Paul Sokolovsky 567bc2d6ce extmod/moducryptolib: Add ucryptolib module with crypto functions.
The API follows guidelines of https://www.python.org/dev/peps/pep-0272/,
but is optimized for code size, with the idea that full PEP 0272
compatibility can be added with a simple Python wrapper mode.

The naming of the module follows (u)hashlib pattern.

At the bare minimum, this module is expected to provide:

* AES128, ECB (i.e. "null") mode, encrypt only

Implementation in this commit is based on axTLS routines, and implements
following:

* AES 128 and 256
* ECB and CBC modes
* encrypt and decrypt
