Remove the #ident and $Log$ strings from all the header files and almost all of the C/C++ source files. I think it is better to get this done all at once, then to wait for each of the files to be touched and edited in unrelated patches.

* The vvp_fun_bufif functor implements the logic of bufif0/1 and
|
|
* notif0/1 gates. Input 0 is the value to be buffered, and input 1 is
|
|
* the enable. The gate processes vectors as bit slices handled by an
|
|
* array of gates.
|
|
*
|
|
* The output from the gate is a vvp_vector8_t. The gate adds
|
|
* strengths to the buffered value, and sends H/L in response to
|
|
* unknown enable bits.
