Fix/New: add variadic function args '...' support to @link

* src/util.h (substitute): add skip_seq to function declaration
* src/util.cpp (substitute): implement skip_seq to keep unchanged a
  given number of sequential chars otherwise targeted for substitution
* src/util.cpp (resolveRef): call substitute() with skip_seq set to 3
  to keep each '...' sequence of chars unchanged

For instance, the command {@link fun(int,...)} now keeps each '...'
sequence of chars unchanged to reference fun(int,...).  Before this
patch, each '.' was substituted into '::' by resolveRef() calling
substitute(), producing a weird reference to fun(int,::::::).
