2014-07-31py: Improve handling of long-int overflow.Damien George
This removes mpz_as_int, since that was a terrible function (it implemented saturating conversion). Use mpz_as_int_checked and mpz_as_uint_checked. These now work correctly (they previously had wrong overflow checking, eg print(chr(10000000000000)) on 32-bit machine would incorrectly convert this large number to a small int).
2014-07-31py: Make MP_OBJ_NEW_SMALL_INT cast arg to mp_int_t itself.Damien George
Addresses issue #724.
2014-07-31stmhal, accel: Increase start-up times to 30ms; add extra 30ms delay.Damien George
For accel to start-up reliably, need to wait 30ms between on/off, and 30ms for it to enter active mode. With this fix the accel can be read immediately after initialising it. Addresses issue #763.
2014-07-31stmhal: Add USB_VCP class/object, for direct USB VCP control.Damien George
Before, pyb.stdin/pyb.stdout allowed some kind of access to the USB VCP device, but it was basic access. This patch adds a proper USB_VCP class and object with much more control over the USB VCP device. Create an object with pyb.USB_VCP(), then use this object as if it were a UART object. It has send, recv, read, write, and other methods. send and recv allow a timeout to be specified. Addresses issue 774.
2014-07-31py: Add mp_obj_str_builder_end_with_len.Damien George
This allows to create str's with a smaller length than initially asked for.
2014-07-30py: Change lexer stream API to return bytes not chars.Damien George
Lexer is now 8-bit clean inside strings.
2014-07-29Merge pull request #738 from dhylands/except-argsDamien George
Add support for storing args during an exception raised by an irq.
2014-07-28py: Implement __file__ attribute for modules.Paul Sokolovsky
2014-07-28py: Make id() return small int for the most common address space mapping.Paul Sokolovsky
Many OSes/CPUs have affinity to put "user" data into lower half of address space. Take advantage of that and remap such addresses into full small int range (including negative part). If address is from upper half, long int will be used. Previously, small int was returned for lower quarter of address space, and upper quarter. For 2 middle quarters, long int was used, which is clearly worse schedule than the above.
2014-07-27py: Change stream protocol API: fns return uint; is_text for text.Damien George
2014-07-25Add support for storing args during an exception raised by an irq.Dave Hylands
The user code should call micropython.alloc_emergency_exception_buf(size) where size is the size of the buffer used to print the argument passed to the exception. With the test code from #732, and a call to micropython.alloc_emergenncy_exception_buf(100) the following error is now printed: ```python >>> import heartbeat_irq Uncaught exception in Timer(4) interrupt handler Traceback (most recent call last): File "0://heartbeat_irq.py", line 14, in heartbeat_cb NameError: name 'led' is not defined ```

2014-07-20stmhal: Fix REPL printing by cooking output sent to stdout_obj.Damien George
Recent changes to builtin print meant that print was printing to the mp_sys_stdout_obj, which was sending data raw to the USB CDC device. The data should be cooked so that \n turns into \r\n.
2014-07-20stmhal: Change calls to pfenv_printf to pfenv_vprintf.Damien George
Fixes printing bugs introduced by cb66f41ebc4980f4e6b7543bece19e3b9daac25c.
2014-07-19py: Make print() accept "file" argument, and actually print to stream.Paul Sokolovsky
And not system printf(), like it was before. For this, move pfenv_printf() from stmhal port to py/.

py: Add stream reading of n unicode chars; unicode support by default.
2014-07-19py: Add stream reading of n unicode chars; unicode support by default.Damien George
With unicode enabled, this patch allows reading a fixed number of characters from text-mode streams; eg file.read(5) will read 5 unicode chars, which can made of more than 5 bytes. For an ASCII stream (ie no chars > 127) it only needs to do 1 read. If there are lots of non-ASCII chars in a stream, then it needs multiple reads of the underlying object. Adds a new test for this case. Enables unicode support by default on unix and stmhal ports.

2014-07-13unix: file: Implement .flush() method.Paul Sokolovsky
This method apparently should be part of stream interface.
2014-07-13test: Add run-tests-exp.sh, script to run testsuite with only sh dependency.Paul Sokolovsky
This script uses expected test results as generated by run-tests --write-exp, and requires only standard unix shell funtionality (no bash). It is useful to run testsuite on embedded systems, where there's no CPython and Bash.
2014-07-13unix: Allow to disable MICROPY_EMIT_X64 from commandline.Paul Sokolovsky
emitnative in particular requires nlr_* to be real functions, so doesn't compile with MICROPY_NLR_SETJMP=1.
