0c7b26c0f8 stream: Return errno value as first arg of OSError exception.

1d8816c36b Deal with reading a buffer less than what was allocated. 
With this fix, file_long_read now passes.

1694bc733d py: Add stream reading of n unicode chars; unicode support by default. 
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.

ec6fa8732b windows: Sync mpconfigport.h with the unix' version 
- rearrange/add definitions that were not there so it's easier to compare both
- use MICROPY_PY_SYS_PLATFORM in main.c since it's available anyway
- define EWOULDBLOCK, it is missing from ingw32

e22cddbe2a stream: Use mp_obj_is_true() for EOF testing. 
Getting a length of string may be expensive, depending on the underlying
implementation.

f600a6a085 py: Slightly improve efficiency of mp_obj_new_str; rename str_new. 
Reorder interning logic in mp_obj_new_str, to be more efficient.

str_new is globally accessible, so should be prefixed with mp_obj_.

a592104acd stream: Add compliant handling of non-blocking read()/write(). 
In case of empty non-blocking read()/write(), both return None. read()
cannot return 0, as that means EOF, so returns another value, and then
write() just follows. This is still pretty unexpected, and typical
"if not len:" check would treat this as EOF. Well, non-blocking files
require special handling!

This also kind of makes it depending on POSIX, but well, anything else
should emulate POSIX anyway ;-).

04b9147e15 Add license header to (almost) all files. 
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

27e735fd18 py: Replace stream_p with *stream_p in mp_obj_type_t. 
This is to reduce ROM usage.  stream_p is used in file and socket types
only (at the moment), so seems a good idea to make the protocol
functions a pointer instead of the actual structure.

It saves 308 bytes of ROM in the stmhal/ port, 928 in unix/.

c5966128c7 Implement proper exception type hierarchy. 
Each built-in exception is now a type, with base type BaseException.
C exceptions are created by passing a pointer to the exception type to
make an instance of.  When raising an exception from the VM, an
instance is created automatically if an exception type is raised (as
opposed to an exception instance).

Exception matching (RT_BINARY_OP_EXCEPTION_MATCH) is now proper.

Handling of parse error changed to match new exceptions.

mp_const_type renamed to mp_type_type for consistency.

698ec21e46 Make mp_obj_str_get_data return char* instead of byte*. 
Can't decide which is better for string type, char or byte pointer.
Changing to char removes a few casts.  Really need to do proper unicode.
