Leo Moser 6c82468031 fabulous: add `-ff` option, remove legacy `-plib`/`-complex-dff` option 
The concept of 'COMPLEX_DFF' is deprecated. Instead, simply specify the supported flip-flops using `-ff <cell_type_pattern> <init_values>` and supply the mapping file.

Fix some synth_* help messages 
Mostly memory_libmap arg checks; puts the checks into an else block on the `if (help_mode)` check to avoid cases like `synth_ice40` listing `-no-auto-huge [-no-auto-huge]`.
Also fix `map_iopad` section being empty in `synth_fabulous`.
