0565f5a3bb hs: Make the service list pruning function public
The reason for making the temporary list public is to keep it encapsulated in
the rendservice subsystem so the prop224 code does not have direct access to
it and can only affect it through the rendservice pruning function.

It also has been modified to not take list as arguments but rather use the
global lists (main and temporary ones) because prop224 code will call it to
actually prune the rendservice's lists. The function does the needed rotation
of pointers between those lists and then prune if needed.

In order to make the unit test work and not completely horrible, there is a
"impl_" version of the function that doesn't free memory, it simply moves
pointers around. It is directly used in the unit test and two setter functions
for those lists' pointer have been added only for unit test.

f02868bb53 hs: Add service-side circuitmap API.
Now we have separate getters and setters for service-side and relay-side. I
took this approach over adding arguments to the already existing methods to
have more explicit type-checking, and also because some functions would grow
too large and dirty.

This commit also fixes every callsite to use the new function names which
modifies the legacy HS (v2) and the prop224 (v3) code.

6bacc3c7a8 hs: Change trunnel prop224 cell's namespace
One of the goals of this change is to have trunnel API/ABI being more explicit
so we namespace them with "trn_*". Furthermore, we can now create
hs_cells.[ch] without having to confuse it with trunnel which used to be
"hs_cell_*" before that change.

Here are the perl line that were used for this rename:

  perl -i -pe 's/cell_extension/trn_cell_extension/g;' src/*/*.[ch]
  perl -i -pe 's/cell_extension/trn_cell_extension/g;' src/trunnel/hs/*.trunnel
  perl -i -pe 's/hs_cell_/trn_cell_/g;' src/*/*.[ch]
  perl -i -pe 's/hs_cell_/trn_cell_/g;' src/trunnel/hs/*.trunnel

  And then "./scripts/codegen/run_trunnel.sh" with trunnel commit id
  613fb1b98e58504e2b84ef56b1602b6380629043.

Fixes #21919

e5fc02c81c config: Warn if EntryNodes and HiddenService are used together
Pinning EntryNodes along with hidden services can be possibly harmful (for
instance #14917 and #21155) so at the very least warn the operator if this is
the case.

26dd4d92cf Remove SR_COMMIT_LEN workaround

f15818f280 Make base64_decode() check actual decoded length
base64_decode() was applying an overly conservative check on the
output buffer length that could incorrectly produce an error if the
input encoding contained padding or newlines.  Fix this by checking
the output buffer length against the actual decoded length produced
during decoding.

4812441d34 Never read off the end of a buffer in base32_encode()
When we "fixed" #18280 in 4e4a7d2b0c
in 0291 it appears that we introduced a bug: The base32_encode
function can read off the end of the input buffer, if the input
buffer size modulo 5 is not equal to 0 or 3.

This is not completely horrible, for two reasons:
   * The extra bits that are read are never actually used: so this
     is only a crash when asan is enabled, in the worst case.  Not a
     data leak.

   * The input sizes passed to base32_encode are only ever multiples
      of 5. They are all either DIGEST_LEN (20), REND_SERVICE_ID_LEN
      (10), sizeof(rand_bytes) in addressmap.c (10), or an input in
      crypto.c that is forced to a multiple of 5.

So this bug can't actually trigger in today's Tor.

Closes bug 21894; bugfix on 0.2.9.1-alpha.

1e54bdd48a Make the warnings about terminating nuls a bit stronger
It looks like 32_encoded_size/64_encode_size APIs are inconsistent
not only in the number of "d"s they have, but also in whether they
count the terminating NUL.  Taylor noted this in 86477f4e3f,
but I think we should note the inconsistently more loudly in order
to avoid trouble.

(I ran into trouble with this when writing 30b13fd82e243713c6a0d.)
