Subject: Some more aacdec cleanups
X-Git-Tag: v0.2.14~132
X-Git-Url: http://git.tue.mpg.de/?a=commitdiff_plain;h=ede4d4615c5a0e41a1dffc83ad78e9aabe1d57a3;p=paraslash.git

Some more aacdec cleanups

rename the "decoder" field to "handle" as it is of type NeAACDecHandle.
Fix some typos in comments and make two more variables local.
