In brief: we go through a lot of gymnastics to handle huge protover
numbers, but after years of development we're not even close to 10
for any of our current versions. We also have a convenient
workaround available in case we ever run out of protocols: if (for
example) we someday need Link=64, we can just add Link2=0 or
something.
This patch is a minimal patch to change tor's behavior; it doesn't
take advantage of the new restrictions.
Implements #40133 and proposal 318.
If at least one service is configured as a version 2, a log warning is emitted
once and only once.
Closes#40003

First, we introduce a flag to teach src/test/test to split its work
into chunks. Then we replace our invocation of src/test/test in our
"make check" target with a set of 8 scripts that invoke the first
8th of the tests, the second 8th, and so on.
This change makes our "make -kj4 check" target in our hardened
gitlab build more than twice as fast, since src/test/test was taking
the longest to finish.
Closes 40098.
The rend_cache/entry_free was missing the rend cache allocation increment
before freeing the object.
Without it, it had an underflow bug:
Sep 17 08:40:13.845 [warn] rend_cache_decrement_allocation(): Bug: Underflow
in rend_cache_decrement_allocation (on Tor 0.4.5.0-alpha-dev
7eef9ced61)
Fixes#40125

Opening a new listener connection can fail in many ways like a bind()
permission denied on a low port for instance.
And thus, we should expect to handle an error when creating a new one instead
of assert() on it.
To hit the removed assert:
ORPort 80
KeepBindCapabilities 0
Start tor. Then edit torrc:
ORPort <some-IP>:80
HUP tor and the assert is hit.
