liboboe: rename Oboe to AAudio
All of the edits were done using scripts in media/liboboe/scripts.
The conversion is done using SED, which is called from
convert_oboe_aaudio.sh
The conversion can be reverted when debugging using revert_all_aaudio.sh
The string substitutions are in oboe_to_aaudio.sed
