9804bdc34e tilelink: remove obsolete addr_lo signal (#895)
When we first implemented TL, we thought this was helpful, because
it made WidthWidgets stateless in all cases. However, it put too
much burden on all other masters and slaves, none of which benefitted
from this signal. Furthermore, even with addr_lo, WidthWidgets were
information lossy because when they widen, they have no information
about what to fill in the new high bits of addr_lo.

f0ffb7e31e tilelink: initialize toggle in Fragmenter (#894)
No strictly necessary, because the initial value does not matter, but good hygiene since it drives a cycle of logic.

c2b8b08461 tilelink: fix Fragmenter source re-use bug (#888)
Consider the following waveform for two 4-beat bursts:
---A----A------------
-------D-----DDD-DDDD
Under TL rules, the second A can use the same source as the first A,
because the source is released for reuse on the first response beat.

However, if we fragment the requests, it looks like this:
---3210-3210---------
-------3-----210-3210
... now we've broken the rules because 210 are twice inflight.

To solve this, we alternate an a.source bit every time D completes a txn.
