Fix timer overflow code.

39296b40d4 Fix timer overflow code.
Teensy doesn't need to worry about overflows since all of
its timers are only 16-bit.

For PWM, the pulse width needs to be able to vary from 0..period+1
(pulse-width == period+1 corresponds to 100% PWM)

I couldn't test the 0xffffffff cases since we can't currently get a
period that big in python. With a prescaler of 0, that corresponds
to a freq of 0.039 (i.e. cycle every 25.56 seconds), and we can't
set that using freq or period.

I also tested both stmhal and teensy with floats disabled, which
required a few other code changes to compile.

133b083b89 py: Clean up nlr*.S to make it easier to read; fix clang .bss error.
It seems that newer versions of clang don't like the .bss directive, so
we don't use it for OSX.

Addressing issues #865 and #875.

b766e79510 stmhal: Initial implementation of cc3k module and driver.
Pulled in and modified work done by mux/iabdalkader on cc3k driver, from
iabdalkader-cc3k-update branch.  That branch was terribly messy and had
too many conflicts to merge neatly.

cde0ca21bf py: Simplify JSON str printing (while still conforming to JSON spec).
The JSON specs are relatively flexible and allow us to use one function
to print strings, be they ascii, bytes or utf-8 encoded.

b0261341d3 py: For malloc and vstr functions, use size_t exclusively for int type.
It seems most sensible to use size_t for measuring "number of bytes" in
malloc and vstr functions (since that's what size_t is for).  We don't
use mp_uint_t because malloc and vstr are not Micro Python specific.

52b5d76a6b py: Free non-interned strings in the parser when not needed.
mp_parse_node_free now frees the memory associated with non-interned
strings.  And the parser calls mp_parse_node_free when discarding a
non-used node (such as a doc string).

Also, the compiler now frees the parse tree explicitly just before it
exits (as opposed to relying on the caller to do this).

Addresses issue #708 as best we can.

eaaebf3291 stmhal: Initialise stack pointer correctly.
Stack is full descending and must be 8-byte aligned.  It must start off
pointing to just above the last byte of RAM.

Previously, stack started pointed to last byte of RAM (eg 0x2001ffff)
and so was not 8-byte aligned.  This caused a bug in combination with
alloca.

This patch also updates some debug printing code.

Addresses issue #872 (among many other undiscovered issues).

0e58c5810d stmhal: Add pulse_width_ratio to timer channel object.
This allows to set the pulse width (for PWM mode) as a ratio relative to
the period of the timer.  Eg, 0.5 is a 50% duty cycle.  You can set the
ratio in the channel init, or using channel.pulse_width_ratio; the
latter can also read the pulse width as a ratio.

8a9b999f1c py: Make dict use a bit less RAM when iterating; properly del values.
Heap RAM was being allocated to print dicts and do some other types of
iterating.  Now these iterations use 1 word of state on the stack.

Deleting elements from a dict was not allowing the value to be reclaimed
by the GC.  This is now fixed.

1d7fb82f0a stmhal: Change 64-bit arithmetic to 32-bit for SD card block addressing.
By measuring SD card addresses in blocks and not bytes, one can get away
with using 32-bit numbers.

This patch also uses proper atomic lock/unlock around SD card
read/write, adds SD.info() function, and gives error code for failed
read/writes.

b92cbe6129 py: Move definition of mp_sys_exit to core.
sys.exit always raises SystemExit so doesn't need a special
implementation for each port.  If C exit() is really needed, use the
standard os._exit function.

Also initialise mp_sys_path and mp_sys_argv in teensy port.
