21eac1e8d8 dns: Make TTLs fuzzy at exit relays 
This change mitigates DNS-based website oracles by making the time that
a domain name is cached uncertain (+- 4 minutes of what's measurable).

Resolves TROVE-2021-009.

Fixes #40674

780ca741f3 relay: Cache onion queue parameters on consensus change 
This is part of the fast path so we need to cache consensus parameters
instead of querying it everytime we need to learn a value.

e3f6908984 relay: Make the max pending tasks per CPU a consensus parameter 
Until now, there was this magic number (64) used as the maximum number
of tasks a CPU worker can take at once.

This commit makes it a consensus parameter so our future selves can
think of a better value depending on network conditions.

ee38514cc4 build: fix -Wstrict-prototypes (Clang 16) 
Clang 16 warns on -Wstrict-prototypes in preparation for C23 which can
among other things, lead to some configure tests silently failing/returning the wrong result.

Fixes this error:
```
-ignoreme: warning: a function declaration without a prototype is deprecated in all versions of C [-Wstrict-prototypes]
+ignoreme: error: a function declaration without a prototype is deprecated in all versions of C [-Werror,-Wstrict-prototypes]
 main ()
```

75d12dffe7 Remove BUG() in Windows process read callback. 
This BUG() was added when the code was written to see if this callback
was ever executed after we marked the handle as EOF. It turns out, it
does, but we handle it gracefully. We can therefore remove the BUG().

Fixes tpo/core/tor#40596.
