refactor(wininfo): change wininfo from a linked list to an array

Browse Source 
"wininfo" is going to be my next victim. The main problem with wininfo
is that it is "all or nothing", i e either all state about a buffer in a
window is considered valid or none of it is. This needs to be fixed to
address some long running grievances.

For now this is just a warmup: refactor it from a linked list to a
vector.
