d8a3d6f378 internal: cleanup proc macro server error handlig 
When dealing with proc macros, there are two very different kinds of
errors:

* first, usual errors of "proc macro panicked on this particular input"
* second, the proc macro server might day if the user, eg, kills it

First kind of errors are expected and are a normal output, while the
second kind are genuine IO-errors.

For this reason, we use a curious nested result here: `Result<Result<T,
E1>, E2>` pattern, which is 100% inspired by http://sled.rs/errors.html

f5c9407a8f This patch shortens the spawned threads' names, as threads on Linux 
have an upper limit of 16 characters for their names.

5e6eee5f63 Explicitly name all spawned threads 
The thread name is shown in debugger as well as panic messages and this
patch makes it easier to follow a thread instead of looking through
full backtrace, by naming all spawned threads according to their
functioning.

9260: tree-wide: make rustdoc links spiky so they are clickable r=matklad a=lf-

Rustdoc was complaining about these while I was running with --document-private-items and I figure they should be fixed.
