3533924c36 extmod/moddeflate: Add deflate module providing the DeflateIO class.
This provides similar functionality to the former zlib.DecompIO and
especially CPython's gzip.GzipFile for both compression and decompression.

This class can be used directly, and also can be used from Python to
implement (via io.BytesIO) zlib.decompress and zlib.compress, as well as
gzip.GzipFile.

Enable/disable this on all ports/boards that zlib was previously configured
for.

add1200343 all: Remove the zlib module.
This will be replaced with a new deflate module providing the same
functionality, with an optional frozen Python wrapper providing a
replacement zlib module.

binascii.crc32 is temporarily disabled.

extmod/modbinascii: Fix buffer length error.
The mod_binascii_a2b_base64() function allocates a buffer which may be
too small. It needs to be no less than three-quarters of the input
length, but is calculated as (<length> / 4) * 3 + 1, which may be less
due to integer division. Changed to (<length> * 3) / 4 + 1.

Updates any includes, and references from Makefiles/CMake.

This essentially reverts what was done long ago in commit
