Here's an attempt to switch libuv to getexecpath(3).
It builds, tests pass, afaict it behaves the same as the other
implementations (i.e. it copies a truncated path and no error
when the path doesn't fit into the buffer).
In lang/node it allows me to drop the current workaround to make
process.execPath work.
It could probably use some adult supervision, though ...
