Since CPython 3.8 the optional "sep" argument to hexlify is officially
supported, so update comments in the code and the docs to reflect this.

'force' in order not to alter the comments which use extra spaces after //

This commit makes all functions and function wrappers in modubinascii.c
STATIC and conditional on the MICROPY_PY_UBINASCII setting, which will
exclude the file from qstr/ compressed-string searching when ubinascii is
not enabled. The now-unused modubinascii.h header file is also removed.
The cc3200 port is updated accordingly to use this module in its entirety
instead of providing its own top-level definition of ubinascii.
This was originally like this because the cc3200 port has its own ubinascii
module which referenced these methods. The plan appeared to be that the
API might diverge (e.g. hardware crc), but this should be done similar to
I2C/SPI via a port-specific handler, rather than the port having its own
definition of the module. Having a centralised module definition also
enforces consistency of the API among ports.
This saves code space in builds which use link-time optimization.
The optimization drops the untranslated strings and replaces them
with a compressed_string_t struct. It can then be decompressed to
a c string.
Builds without LTO work as well but include both untranslated
strings and compressed strings.
This work could be expanded to include QSTRs and loaded strings if
a compress method is added to C. Its tracked in #531.
Textualy, the files in lib/uzlib/src were identical to the ones committed
in extmod/uzlib so there should be no behavioral change possible as a
result of this commit.
.. this maybe should be subject to MICROPY_CPYTHON_COMPAT, except that
is not defined in the main circuitpython ports so it would be a change
that makes no difference.
Header files that are considered internal to the py core and should not
normally be included directly are:
py/nlr.h - internal nlr configuration and declarations
py/bc0.h - contains bytecode macro definitions
py/runtime0.h - contains basic runtime enums
Instead, the top-level header files to include are one of:
py/obj.h - includes runtime0.h and defines everything to use the
mp_obj_t type
py/runtime.h - includes mpstate.h and hence nlr.h, obj.h, runtime0.h,
and defines everything to use the general runtime support functions
Additional, specific headers (eg py/objlist.h) can be included if needed.
This implementation ignores invalid characters in the input. This allows
it to decode the output of b2a_base64, and also mimics the behavior of
CPython.
- Changed: ValueError, TypeError, NotImplementedError
- OSError invocations unchanged, because the corresponding utility
function takes ints, not strings like the long form invocation.
- OverflowError, IndexError and RuntimeError etc. not changed for now
until we decide whether to add new utility functions.
With this patch str/bytes construction is streamlined. Always use a
vstr to build a str/bytes object. If the size is known beforehand then
use vstr_init_len to allocate only required memory. Otherwise use
vstr_init and the vstr will grow as needed. Then use
mp_obj_new_str_from_vstr to create a str/bytes object using the vstr
memory.
Saves code ROM: 68 bytes on stmhal, 108 bytes on bare-arm, and 336 bytes
on unix x64.
