Make the codebase compatible with PHP 7.1

This is the bash script used to make this patch:

for f in $(find src/ tests/ -type f -not -wholename 'tests/ProxyManagerTestAsset/*')
do
    echo $f
    sed -i 's/\(\(public\|protected\|private\) \(static \)*\)\(?*[a-zA-Z|_][a-zA-Z|_0-9]* \)*\$/\1\$/' $f
    sed -i 's/ *: ?*object\(;*\)$/\1/' $f
    sed -i 's/\((\|, \|^  *\)?*object *\(& \)*\$/\1\2$/g' $f
    sed -i 's/\([^ ]*\) ??=/\1 = \1 ??/' $f
    sed -i 's/^\([A-Z][A-Z_]*\),/\1\n,/' $f
done
