923a8a8320 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.

9b0b373e5e py: Fix GC realloc issue, where memory chunks were never shrunk. 
Previously, a realloc to a smaller memory chunk size would not free the
unused blocks in the tail of the chunk.

c14a81662c py: Add module weak link support. 
With this patch a port can enable module weak link support and provide
a dict of qstr->module mapping.  This mapping is looked up only if an
import fails to find the requested module in the filesystem.

This allows to have the builtin module named, eg, usocket, and provide
a weak link of "socket" to the same module, but this weak link can be
overridden if a file by the name "socket.py" is found in the import
path.

c4d0868df1 py: Implement proper context save/restore for eval/exec; factor code. 
This has benefits all round: code factoring for parse/compile/execute,
proper context save/restore for exec, allow to sepcify globals/locals
for eval, and reduced ROM usage by >100 bytes on stmhal and unix.

Also, the call to mp_parse_compile_execute is tail call optimised for
the import code, so it doesn't increase stack memory usage.

8b03d944e2 py: Remove IOError since it's deprecated; use OSError instead. 
In CPython IOError (and EnvironmentError) is deprecated and aliased to
OSError.  All modules that used to raise IOError now raise OSError (or a
derived exception).

In Micro Python we never used IOError (except 1 place, incorrectly) and
so don't need to keep it.

See http://legacy.python.org/dev/peps/pep-3151/ for background.

e9dac3b4d0 py: Add casting to viper; add native mem stores to viper. 
Viper can now do the following:

def store(p:ptr8, c:int):
    p[0] = c

This does a store of c to the memory pointed to by p using a machine
instructions inline in the code.
