perf(l2): long lists build only the rows on screen

New message, Nodes (and its Scan popup), Admin and Messages show their
items through one virtual list: a screenful of rows, handed to the next
item as one scrolls out, the scroll extent from the items' heights. 256
contacts: 522 objects and ~950 ms of filling in (frames up to 96 ms)
before, 19 objects at once now; a scrolled frame 28.5 -> 11.7 ms. Nodes
257 -> 49 objects. A new message rewrites Messages' rows in place
(46 -> 20 ms) instead of building the screen again; it's rebuilt only
when "Read all" comes or goes. A held row keeps what it shows until let
go. Perf tools: -D PERF_LISTS, -D PERF_LIST_MUL.
