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.

Jim Mussared 45ac651d1a all: Rename *umodule*.c to remove the "u" prefix. 
Updates any includes, and references from Makefiles/CMake.

This essentially reverts what was done long ago in commit
