Modify the definition and use of EXPORT_SYMBOL as was done for libmnl in
commit 444d6dc9.
Additionally, avoid generating long (>80ch) lines when inserting
EXPORT_SYMBOL by splitting these lines at start of function name (was already
done in a few places).
Finally, re-align multi-line parameter blocks with opening parenthesis.
