Damien George e08ca78f40 py/stream: Remove mp_stream_errno and use system errno instead. ... This change is made for two reasons: 1. A 3rd-party library (eg berkeley-db-1.xx, axtls) may use the system provided errno for certain errors, and yet MicroPython stream objects that it calls will be using the internal mp_stream_errno. So if the library returns an error it is not known whether the corresponding errno code is stored in the system errno or mp_stream_errno. Using the system errno in all cases (eg in the mp_stream_posix_XXX wrappers) fixes this ambiguity. 2. For systems that have threading the system-provided errno should always be used because the errno value is thread-local. For systems that do not have an errno, the new lib/embed/__errno.c file is provided.		2020-04-27 23:58:46 +10:00
