2019-05-19widgets/terminal: fix damage race conditionSimon Ser
Terminal.damage is accessed when drawing and when invalidating the widget. For this reason we need to protect it with a mutex. This seems to fix various damage issues I've been experiencing (where some regions of the terminal weren't correctly repainted).

2019-04-27lib/ui: introduce InvalidatableSimon Ser
Many Drawable implementations have their own Invalidate and OnInvalidate functions, with an unexported onInvalidate field. However OnInvalidate and Invalidate are usually not called in the same goroutine. This results in a race on this field, e.g.: Read at 0x00c000094748 by goroutine 7: git.sr.ht/~sircmpwn/aerc2/widgets.NewDirectoryList.func1() /home/simon/src/aerc2/widgets/dirlist.go:85 +0x56 git.sr.ht/~sircmpwn/aerc2/widgets.(*Spinner).Start.func1() /home/simon/src/aerc2/widgets/spinner.go:93 +0x1bb Previous write at 0x00c000094748 by main goroutine: [failed to restore the stack] Goroutine 7 (running) created at: git.sr.ht/~sircmpwn/aerc2/widgets.(*Spinner).Start() /home/simon/src/aerc2/widgets/spinner.go:46 +0x8f git.sr.ht/~sircmpwn/aerc2/widgets.NewDirectoryList() /home/simon/src/aerc2/widgets/dirlist.go:37 +0x286 git.sr.ht/~sircmpwn/aerc2/widgets.NewAccountView() /home/simon/src/aerc2/widgets/account.go:50 +0x5ca git.sr.ht/~sircmpwn/aerc2/widgets.NewAerc() /home/simon/src/aerc2/widgets/aerc.go:60 +0x800 main.main() /home/simon/src/aerc2/aerc.go:65 +0x33e To fix this, introduce a new type, Invalidatable, which protects the field. Unfortunately the Drawable must be passed to the callback function in Invalidate, so we still need to re-implement this in each Invalidatable user.
