97da92d894 Whitespace cleanup: Remove all multiple newlines
This patch removes all occurrences of double and triple
newlines.

Command used for this:
find .  -type d \( -name ffmpeg \) -prune -o \
        -regex '\(.*\.[hc]\|.*\.cc\)' \
        -a -not -name 'adrian-aec.*' -a -not \
        -name reserve.c -a -not -name 'rtkit.*' \
        -exec sed -i -e '/^$/{N;s/^\n$//}' {} \;

Two passes were needed to remove triple newlines.
The excluded files are mirrored files from external sources.
