Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Dynamically load X11 libraries like we currently do for alsa, esd, etc. This allows you to run an SDL program on a system without Xlib, since it'll just report the x11 target unavailable at runtime.
