The original purpose of this commit is to replace some for loops with list_find. But while doing this I found the workspace_prev_next_impl functions to be difficult to read and also contained a bug, so I refactored them and fixed the bug. To reproduce the bug: * Have two outputs, where the left output has workspaces 1, 2, 3 and the right output has workspaces 4, 5, 6. Make workspace 2 focused_inactive and workspace 4 focused. * Run `workspace prev`. * Previously it would visit the left output, then apply `workspace prev` to workspace 2, which focuses workspace 1. * Now it will focus the rightmost workspace on the left output (workspace 3). The refactoring I made to the workspace functions are: * Added the static keyword. * They now accept an int dir rather than bool, to avoid an unnecessary conversion. * Rather than preparing start and end variables for the purpose of iterating, just iterate everything. * Replace for loops with list_find. * Don't call workspace_output_prev_next_impl (this fixes the bug).
