bc1488a05f stmhal: Improve REPL control codes; improve pyboard.py script.
Improvements are:

2 ctrl-C's are now needed to truly kill running script on pyboard, so
make CDC interface allow multiple ctrl-C's through at once (ie sending
b'\x03\x03' to pyboard now counts as 2 ctrl-C's).

ctrl-C in friendly-repl can now stop multi-line input.

In raw-repl mode, use ctrl-D to indicate end of running script, and also
end of any error message.  Thus, output of raw-repl is always at least 2
ctrl-D's and it's much easier to parse.

pyboard.py is now a bit faster, handles exceptions from pyboard better
(prints them and exits with exit code 1), prints out the pyboard output
while the script is running (instead of waiting till the end), and
allows to follow the output of a previous script when run with no
arguments.

480a7ce58f stmhal: Change SPI phase spec to 0,1 to match standard conventions.
Was 1 or 2, now 0 or 1 (respectively).  0 means sample MISO on first
edge, 1 means sample on second edge.

Addresses issue #936.

124df6f8d0 py: Add mp_pending_exception global variable, for VM soft interrupt.
This allows to implement KeyboardInterrupt on unix, and a much safer
ctrl-C in stmhal port.  First ctrl-C is a soft one, with hope that VM
will notice it; second ctrl-C is a hard one that kills anything (for
both unix and stmhal).

One needs to check for a pending exception in the VM only for jump
opcodes.  Others can't produce an infinite loop (infinite recursion is
caught by stack check).

d7353fe6fe stmhal: Change USB PID when in CDC+HID mode.
This gets CDC+HID working on Windows, since it needs a different PID for
a different USB configuration.

Thanks to tmbinc and dhylands.

d46a822262 Fixed TIM2_CH1 definition.
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.

3e42570538 stmhal: Change cc3k.recv to only make 1 call to underlying recv().
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.

481d714bd5 stmhal: Overhaul UART class to use read/write, and improve it.
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.

2fe4cf7761 Implement kwargs for builtin open() and _io.FileIO
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

abf0f07a5a stmhal: Set entry point for ELF binary debugging
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.

1a55b6a787 unix, stmhal: Implement file.readinto() method.
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.

1c795445b3 Add support for complimentary channel output and deadtime.
This patch enables output on the complimentary channels (TIMx_CHyN).
For timers 1 and 8, deadtime can also be inserted when the channels
transition. For the pyboard, TIM8_CH1/CH1N and TIM8_CH2/CH2N can
take advantage of this.

d03c681608 stmhal: Use mp_uint_t where appropriate.
Found these by compiling stmhal with mp_uint_t of type uint32_t instead
of unsigned int.  This actually makes a difference to the code, but just
a curiosity.

Timers now have the following new features:
- can init freq using floating point; eg tim.init(freq=0.1)
- tim.source_freq() added to get freq of timer clock source
- tim.freq() added to get/set freq
- print(tim) now prints freq

24119176e7 stmhal: Allow pyb.freq() function to change SYSCLK frequency.
Eg pyb.freq(120000000) sets the CPU to 120MHz.  The frequency can be set
at any point in the code, and can be changed as many times as you like.
Note that any active timers will need to be reconfigured after a freq
change.

Valid range is 24MHz to 168MHz (but not all freqs are supported).  The
code maintains a 48MHz clock for the USB at all times and it's possible
to change the frequency at a USB REPL and keep the REPL alive (well,
most of the time it stays, sometimes it resets the USB for some reason).
Note that USB does not work with pyb.freq of 24MHz.
