In unix port, mem_info(1) now prints pretty GC alloc table.

Also move the raw bytecode printing code from emitglue to mp_bytecode_print.

While extension to file.readinto() definition of CPython, the additional arg
is similar to what in CPython available in socket.recv_into().

Addresses issue #927.

You can do:

make USE_PYDFU=1 deploy

to use pydfu.py

It's purpose is for internal errors that are not catastrophic (ie not as
bad as RuntimeError).  Since we don't use it, we don't need it.

This allows you to register ExtInt on the MMA interrupt pin.

TIM2_CH1_ETR is really bundling 2 functions to the same pin:
TIM2_CH1 (where its used as a channel)
TIM2_ETR (where iss used as an external trigger).

I fixed most of these a while back, but it looks like I missed this one.

There is no need, since we don't (currently) use the value.

Also make cc3k.send and cc3k.recv independent functions (not wrapped by
stream write/read).  Also make wiznet5k.recv more memory efficient.

This might address issue #920.

UART object now uses a stream-like interface: read, readall, readline,
readinto, readchar, write, writechar.

Timeouts are configured when the UART object is initialised, using
timeout and timeout_char keyword args.

The object includes optional read buffering, using interrupts.  You can set
the buffer size dynamically using read_buf_len keyword arg.  A size of 0
disables buffering.

stmhal: Set entry point for ELF binary debugging

mode argument is used to assert it works
encoding argument is used to make sure CPython uses the correct encoding
as it does not automatically use utf-8

This makes open() and _io.FileIO() more CPython compliant.
The mode kwarg is fully iplemented.
The encoding kwarg is allowed but not implemented; mainly to allow
the tests to specify encoding for CPython, see #874

When loading the ELF binary to the board with a debugger, the debugger
needs to know at which point to start executing the code. Currently the
entry point defaults to the start of the .text section.

This fixed an issue with a certain SD card sometimes not initialising
first time round.  See issue #822 for related, and thanks to
@iabdalkader for the idea.

Also, usocket.readinto(). Known issue is that .readinto() should be available
only for binary files, but micropython uses single method table for both
binary and text files.
