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 ()
```

256339712d Strip "__.SYMDEF*" before re-archiving in combine_libs on macOS and iOS.
This patch changes how combine_libs works on Darwin like platforms to
make sure we don't include any `__.SYMDEF` and `__.SYMDEF SORTED`
symbols on the archive before we repack and run ${RANLIB} on the
archive.
