clang-format: Switch to ColumnLimit 0

clang-format: Switch to ColumnLimit 0

In some cases an actual ColumnLimit leads to unfortunate
formatting. So leave the decision to developers after all.

This commit contains:
 - changes that clang-format did as reaction to the config
   change
 - manual cleanups of these changes
 - manual cleanup of some previous changes done
   with ColumnLimit 100
