Ever read gdb output and you just kinda get a headache because you have
to infer what a thread is by reading the stack trace? It's not hard, but
we could also just never have to do that again, which is also not hard.
Sample:
(gdb) info thr
Id Target Id Frame
* 1 LWP 3719283 "nix-daemon" 0x00007e558587da0f in accept ()
from target:/nix/store/c10zhkbp6jmyh0xc5kd123ga8yy2p4hk-glibc-2.39-52/lib/libc.so.6
2 LWP 3719284 "signal handler" 0x00007e55857b2bea in sigtimedwait ()
from target:/nix/store/c10zhkbp6jmyh0xc5kd123ga8yy2p4hk-glibc-2.39-52/lib/libc.so.6
The API design for this is forced by the macOS pthread_setname_np only
being able to change the current thread's name, but if we just conform
everything to that, it works everywhere.

Lix now sets thread names on all of its secondary threads, which will make debugger usage slightly nicer and easier.
