whitequark 1b54eb80da vendor.board: split off into nmigen-boards package. 
The iCE40 programmers are also moved, since they're board-specific.
(It looks like iceprog isn't, but it only works with Lattice
evaluation kits.)

Fixes #80.

whitequark f417725b10 build.res: if not specified, request resource #0. 
This markedly differs from oMigen system, which would request
consecutive resources. The difference is deliberate; most resources
are singular, so it does not matter for them, and for resources where
it does matter, which pins are requested should not depend on order
of execution of `platform.request`.

whitequark aed2062101 Remove examples/tbuf.py. 
This example predates the plans for nmigen.build, and indeed
get_tristate and TSTriple no longer exist.

whitequark 44711b7d08 hdl.ir: detect elaboratables that are created but not used. 
Requres every elaboratable to inherit from Elaboratable, but still
accepts ones that do not, with a warning.

Fixes #3.
