Comment (by yawning):

 To keep this on people's radar... I pushed a bunch more commits to the _v3
 branch, that I shall squash/rebase once it's passed review.

 tests....disturbing.</span>

 This should be the last thing required.

 >  * What motivates the memwipe in crypto_pk_base64_encode() ?

 aa5af50a32719c2ade2d9b86b1c0ae26686e92c4 - adds a comment.  The correct
 fix requires #15652.

 >  * Can we split the command-parsing part of add_onion handling into its
 own function, so that it can be tested separately?  It's pretty bulky...

 9d2b42fd61e63c9b9e9ea1bdcb3b77a58a72eb20 - Carves out the key argument
 parsing stuff.
 8c31713d34287232461f21d4f7d02992b2c25aa7 - Makes add_onion use the
 rend_service port config parser.

 It's still a tad bulky, but significantly less so, and more testable.
 Reducing it further is possible, but all the control code tends to be a
 gigantic ball of bulk, so I don't feel too bad about it in it's current
 state.

 >  * Let's turn the return values from rend_service_add_ephemeral into an
 enum.

 >  * I'm not fond of naming variables l, because of I and 1.

 >  * The new return value for rend_add_service needs to get documented.

 Just needs tests at this point.  I'll write ones for the new stuff in
 `common/crypto.c` and the testable parts of the add_onion handler.
