cb0fc063ed objmemoryview: Introduce mp_obj_new_memoryview(). 
This follows existing pattern for object constructor API and allows to
create memoryview objects e.g. in external modules.

24c1000741 objarray: Support array('O'), array of objects, as extension to CPython. 
Might be useful at least for memoryview hacks.

3665d0b2ff py: Simplify some inline-assembler error messages, but retain meaning. 
Just to reduce code size.  Messages are still to the point and
unambiguous.

67c5f89af5 py: In inline assembler, fix branch out-of-range error reporting. 
Should only give an error on the last pass of the assembler, since
that's when we are certain about the branch size.

cefcbb22b2 objarray: Implement array slice assignment. 
This is rarely used feature which takes enough code to implement, so is
controlled by MICROPY_PY_ARRAY_SLICE_ASSIGN config setting, default off.
But otherwise it may be useful, as allows to update arbitrary-sized data
buffers in-place.

Slice is yet to implement, and actually, slice assignment implemented in
such a way that RHS of assignment should be array of the exact same item
typecode as LHS. CPython has it more relaxed, where RHS can be any sequence
of compatible types (e.g. it's possible to assign list of int's to a
bytearray slice).

Overall, when all "slice write" features are implemented, it may cost ~1KB
of code.

4852e09c79 py: Fix adding of traceback so that it appends to existing info. 
This makes exception traceback info self contained (ie doesn't rely on
list object, which was a bit of a hack), reduces code size, and reduces
RAM footprint of exception by eliminating the list object.

Addresses part of issue #1126.

12d6d777e1 py: Small optimisation of logic flow in BC_WITH_CLEANUP bytecode. 
Slightly smaller code, and does not need to use C stack to save
temporaries.

71ebd4b7f0 py: Implement UnicodeError. 
Still too shy to implement UnicodeEncodeError which was really needed for
micropython-lib case.

5cbeacebdb py: Make math special functions configurable and disabled by default. 
The implementation of these functions is very large (order 4k) and they
are rarely used, so we don't enable them by default.

They are however enabled in stmhal and unix, since we have the room.

1f91e92cc6 py: Revamp mp_obj_print() to use Python streams. 
Most of printing infrastructure now uses streams, but mp_obj_print() used
libc's printf(), which led to weird buffering issues in output. So, switch
mp_obj_print() to streams too, even though it may make sense to move it to
a separate file, as it is purely a debugging function now.

9e6c82960e builtinimport: Revamp&refactor handling of relative imports. 
Relative imports are based of a package, so we're currently at a module
within a package, we should get to package first.

Also, factor out path travsering operation, but this broke testing for
boundary errors with relative imports. TODO: reintroduce them, together
with proper tests.

fa3b895145 objexcept: Optimize traceback allocation for exception. 
Traceback allocation for exception will now never lead to recursive
MemoryError exception - if there's no memory for traceback, it simply
won't be created.

29c4f92e13 objexcept: Optimize using messages without formatting substitutions.

3077fbff26 nlr: Add even more optional debugging logging. 
Has to be enabled by manual editing, but at least it's there, as debugging
NLR issues may be weird.

e89cc13e5c nlr: If DEBUG, guard against recursive nlr_push(). 
Pushing same NLR record twice would lead to "infinite loop" in nlr_jump
(but more realistically, it will crash as soon as NLR record on stack is
overwritten).
