no_std support?

[hadronized]

Hey,

I’d be interested in using this library, but I need the no_std support. Do you have anything for this? Would you accept a patch for it (if it’s easy)? Otherwise, I’ll just wrap my own functions in my (very specific) code, but if others are interested…

Kudos for the good work!

I'm interested in this too. Both crates already use the libc crate, which provides primitives like c_int that the x11 library relies on. x11-dl would be harder, since it relies on lazy_static, and spinlocking might not be in the best interest here. I could probably write this PR by the end of the week.
