Readability, no change in behaviour, but for one log line:
- The routes a peer holds from us were counted twice over, differently,
in the exporter: once per learned-route batch and once per originated
route. Learned::held_by_peer counts the learned ones in one place, and
ExportLimits::exceeded_by returns the limit that was passed instead of a
bool, so that ending the session no longer has to dig it out again with
a default that could not happen.
- The two hold-downs for a limit passed, ours or the peer's, were two
near-identical blocks; they are one match.
- How a session ended is put into words in one place
(SessionEnd::reason), for the dialer's backoff and the passive peer's
state alike.
- parse_export_limits parses one block; what a missing block means (no
limits at the top, the top's limits for a peer) is said where it
differs, instead of Option in and Option out.
- The startup warnings about export limits are a function of their own,
and the peers without limits are named in one line rather than one
line each: a router with eighty sessions does not need eighty warnings.
The warning about a peer without a role is gone: the configuration now
refuses one.
- Hex formatting of attribute octets is one function; the text for an
unknown attribute is built in three plain steps.
- The exporter's test fixture returns a named struct, not a tuple.
