12a9cfed76 modsocket: Make .send() support arbitrary objects with buffer interface. 
This is CPython-compliant (except that CPython doesn't support buffer
protocol for str).

45fb143ba6 streams: Make .write() support arbitrary objects with buffer interface.

1463c1fa82 py: Add MICROPY_ENABLE_DOC_STRING, disabled by default. 
Also add a few STATIC's to some compile functions that should have them.

daab651c5c py, gc: Zero out newly allocated blocks in the GC. 
Also add some more debugging output to gc_dump_alloc_table().

Now that newly allocated heap is always zero'd, maybe we just make this
a policy for the uPy API to keep it simple (ie any new implementation of
memory allocation must zero all allocations).  This follows the D
language philosophy.

Before this patch, a previously used memory block which had pointers in
it may still retain those pointers if the new user of that block does
not actually use the entire block.  Eg, if I want 5 blocks worth of
heap, I actually get 8 (round up to nearest 4).  Then I never use the
last 3, so they keep their old values, which may be pointers pointing to
the heap, hence preventing GC.

In rare (or maybe not that rare) cases, this leads to long, unintentional
"linked lists" within the GC'd heap, filling it up completely.  It's
pretty rare, because you have to reuse exactly that memory which is part
of this "linked list", and reuse it in just the right way.

This should fix issue #522, and might have something to do with
issue #510.

5d3a830171 modsocket: Clean up OSError-like exception a bit. 
Some BSD socket functions don't return error numbers in errno namespace, but
rather in other error namespaces. CPython resolves this by using OSError
subclasses for them. We don't do that so far, so there's ambiguity here.

6125ba4a7f stmhal: Make switch a class, to follow suit of all other modules. 
Instead of pyb.switch() as a function, it's more consistent (with
respect to all the other modules and peripherals) to have
pyb.Switch() create a switch object.  This then generalises to having
multiple switches.  Call the object to get its state.  Use sw.callback
to set the callback function for when the switch is pressed.

Simple but functional timer control.  More sophistication will
eventually be added, or for now just use direct register access :)

7533700393 stmhal: Rename USART to UART. 
It's really a UART because there is no external clock line (and hence no
synchronous ability, at least in the implementation of this module).
USART should be reserved for a module that has "S"ynchronous capabilities.

Also, UART is shorter and easier to type :)

is probably not a complete fix.
