stream: Implement seek operation support via ioctl, wrapped in generic method.
...
Also, implement for unix port.

stream: Add optional 2nd "length" arg to .readinto() - extension to CPython.
...
While extension to file.readinto() definition of CPython, the additional arg
is similar to what in CPython available in socket.recv_into().

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.

stream: Handle non-blocking errors in readline() properly.
...
Just like they handled in other read*(). Note that behavior of readline()
in case there's no data when it's called is underspecified in Python lib
spec, implemented to behave as read() - return None.

Deal with reading a buffer less than what was allocated.

With this fix, file_long_read now passes.

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.

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

stream: Use mp_obj_is_true() for EOF testing.

Getting a length of string may be expensive, depending on the underlying
implementation.

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_.
