ede8a0235b py/vstr: Raise a RuntimeError if fixed vstr buffer overflows.
Current users of fixed vstr buffers (building file paths) assume that there
is no overflow and do not check for overflow after building the vstr.  This
has the potential to lead to NULL pointer dereferences
(when vstr_null_terminated_str returns NULL because it can't allocate RAM
for the terminating byte) and stat'ing and loading invalid path names (due
to the path being truncated).  The safest and simplest thing to do in these
cases is just raise an exception if a write goes beyond the end of a fixed
vstr buffer, which is what this patch does.  It also simplifies the vstr
code.

7885a425d7 py/stream: Remove unnecessary checks for NULL return from vstr_add_len.
The vstr argument to the calls to vstr_add_len are dynamically allocated
(ie fixed_buf=false) and so vstr_add_len will never return NULL.  So
there's no need to check for it.  Any out-of-memory errors are raised by
the call to m_renew in vstr_ensure_extra.

96fd80db13 py/objexcept: Prevent infinite recursion when allocating exceptions.
The aim of this patch is to rewrite the functions that create exception
instances (mp_obj_exception_make_new and mp_obj_new_exception_msg_varg) so
that they do not call any functions that may raise an exception.  Otherwise
it's possible to create infinite recursion with an exception being raised
while trying to create an exception object.

The two main things that are done to accomplish this are:
1. Change mp_obj_new_exception_msg_varg to just format the string, then
   call mp_obj_exception_make_new to actually create the exception object.
2. In mp_obj_exception_make_new and mp_obj_new_exception_msg_varg try to
   allocate all memory first using functions that don't raise exceptions
   If any of the memory allocations fail (return NULL) then degrade
   gracefully by trying other options for memory allocation, eg using the
   emergency exception buffer.
3. Use a custom printer backend to conservatively format strings: if it
   can't allocate memory then it just truncates the string.

As part of this rewrite, raising an exception without a message, like
KeyError(123), will now use the emergency buffer to store the arg and
traceback data if there is no heap memory available.

Memory use with this patch is unchanged.  Code size is increased by:

   bare-arm:  +136
minimal x86:  +124
   unix x64:   +72
unix nanbox:   +96
      stm32:   +88
    esp8266:   +92
     cc3200:   +80

9dce823cfd py/modbuiltins: Implement abs() by dispatching to MP_UNARY_OP_ABS.
This allows user classes to implement __abs__ special method, and saves
code size (104 bytes for x86_64), even though during refactor, an issue
was fixed and few optimizations were made:

* abs() of minimum (negative) small int value is calculated properly.
* objint_longlong and objint_mpz avoid allocating new object is the
  argument is already non-negative.

d7cd1d2027 stm32/timer: Make pyb.Timer() instances persistent.
Prior to this patch calling pyb.Timer(id) would always create a new timer
instance, even if there was an existing one.  This patch fixes this
behaviour to match other peripherals, like UART, such that constructing a
timer with just the id will retrieve any existing instances.

The patch also refactors the way timers are validated on construction to
simplify and reduce code size.

eb84a830df py/runtime: Implement dispatch for "reverse op" special methods.
If, for class X, X.__add__(Y) doesn't exist (or returns NotImplemented),
try Y.__radd__(X) instead.

This patch could be simpler, but requires undoing operand swap and
operation switch to get non-confusing error message in case __radd__
doesn't exist.

9b4666dad5 esp8266/posix_helpers: Set ENOMEM on memory alloc failure.
POSIX requires malloc(), etc. to set ENOMEM on the failure, and e.g.
BerkeleyDB relies on this:

19f1b39d6f stm32/i2c: When scanning for I2C devices only do 1 probe per address.
Previous to this patch the i2c.scan() method would do up to 100 probes per
I2C address, to detect the devices on the bus.  This repeated probing was a
relic from when the code was copied from the accelerometer initialisation,
which requires to do repeated probes while waiting for the accelerometer
chip to turn on.

But I2C devices shouldn't need more than 1 probe to detect their presence,
and the generic software I2C implementation uses 1 probe successfully.  So
this patch changes the implementation to use 1 probe per address, which
significantly speeds up the scan operation.

b8ee7ab5b9 py/runtime0.h: Put inplace arith ops in front of normal operations.

c460f6f15a py/runtime0.h: Regroup operations a bit.
Originally, there were grouped in blocks of 5, to make it easier e.g.
to assess and numeric code of each. But now it makes more sense to
group it by semantics/properties, and then split in chunks still,
which usually leads to chunks of ~6 ops.

50b9329eba py/runtime0.h: Move MP_BINARY_OP_DIVMOD to the end of mp_binary_op_t.
It starts a dichotomy of mp_binary_op_t values which can't appear in the
bytecode. Another reason to move it is to VALUES of OP_* and OP_INPLACE_*
nicely adjacent. This also will be needed for OP_REVERSE_*, to be soon
introduced.
