  Hi,

This patch series adds a new nextpnr package (strongly based on former nextpnt-ice40), common to all derived nextpnr-xxx, which will inherit from it.

Other device packages will follow (nextpnr-ecp5, which uses prjtrellis as backend, for example). See [0]

First commit

- updates to 0.8
- updates substitutions in Makefiles

Second commit modifies the device specific nextpnr-ice40, which now inherits from nextpnr, using icestorm as a backend. With respect to nextpnr:

- adds icestorm as propagated input
- adds yosys as native input, for tests
- addapts config flags to ice40 architecture
- uses tests from icestorm/examples
