Explicitly mention every options in .clang-format to protect us from possible
future changes.
Remove separate InnoDB style.
Change style to look more like this script:
for x in $@
do
indent -kr -bl -bli0 -l79 -i2 -nut -c48 -dj -cp0 $x
sed -ri -e 's/ = /= /g'\
-e '/switch.*\)$/{N;s/\n[ ]+/ /}' $x
done
Significant different is that 'switch' and '{' are put on different lines
because it's impossible in clang-format to set formatting rules just for
'switch' statement.
