Paul Sokolovsky 1b146e9de9 py/mpconfig: Introduce reusable MP_HTOBE32(), etc. macros. 
Macros to convert big-endian values to host byte order and vice-versa.
These were defined in adhoc way for some ports (e.g. esp8266), allow
reuse, provide default implementations, while allow ports to override.

POSIX requires malloc(), etc. to set ENOMEM on the failure, and e.g.
BerkeleyDB relies on this:

This should fix confusing OSError exceptions with 0 error code when
working with btree module.
