1. removed some duplicate symbol linker error
2. removed many compiler warnings (mainly size_t/int compatibility)
3. consistent definition of db::pcell_id_type
4. removed UTF-8 character codes from string constants
5. float constants for float arguments
6. timeout in tlHttp when no openssl lib is found (instead of stalling
app)
Sometimes, shapes from child cells were propagated into
parent cells in the L2N and LVSDB output.
Because of this fix, many testdata files have to be updated.
- some refactoring
- better performance (was slow because layer iteration
was done outside of loop and recursive cluster iterator)
- with selected nets, only the required hierarchy is
produced. For this a new argument is added to
LayoutToNetlist::create_cell_mapping (nets) which
allows selecting the nets for which a cell mapping
is requested
