86699b42f6 Switch to potentially-sparse net users array 
This uses a new data structure for net.users that allows gaps, so
removing a port from a net is no longer an O(n) operation on the number
of users the net has.

3894a36ddb gowin: recognize partnumbers of GW1NZ-1 
The model should be recognized by the partnumber, --family is needed
only if the same partnumbers belong to different models.
This is done in order to automatically generate parameters for calling
nextpnr from Gowin files without problems: there also only partnumber is
used and only in some cases the model is specified with the -name
parameter and GW1NZ-1 is not such a case.

ad49b7c78d gowin: Add support for true differential output 
The new primitive appears as an amalgamation of two existing OBUF
primitives.  Compatible with older versions of apicula, although, of
course, using TLVDS_OBUF with old databases will not bring the desired
result, but no crash.

5c30093360 nexus: reduce OSCA worst case to 7% 
The current version of Crosslink-NX Family Data Sheet lists the high
frequency oscillator maximum frequency as 481.5MHz (that is, 7% higher
than its nominal 450MHz):

https://www.latticesemi.com/-/media/LatticeSemi/Documents/DataSheets/CrossLink/FPGA-DS-02049-1-2-1-CrossLink-NX-Family.ashx?document_id=52780

Older documents listed a wider frequency range but ±7% is the range for
production parts.

230de1e68a gowin: add an option to manually specify family 
In the vendor IDE, there's a device family named GW1N-9C (which seems to
mean C revision of GW1N-9), in which the model numbers are all the same
with GW1N-9.

Add an option to nextpnr-gowin to allow manually specified family for
this situation.
