When processing a new block, attemps to make the scope of the
corresponding `txhashet` lock as small as possible. The idea is
to avoid bad interactions with orphan locks or block post
processing (i.e. adapter events, etc)
Mostly to support let's encrypt. It requires to switch from native-tls and friends to rustls and friends, which perhap is a good thing per se, rustls looks more modern and for sure more Rusty.
Alternative would be manually convert pkcs12 certificates to pem, which requires openssl tools to be installed and make transparent integration whith let's encrypt much harder (this is out of the scope for now, perhaps in near future)
* Go back to db for head and header_head
* Use batch consistently for db access
* Pass active txhashset and batch in the ctx
* Only update head in db if total work increases
* Only updated header_head if total work (on header chain) increases
Picks a random defunct peer and marks it healthy again anytime
we're querying peers to find more. Over enough time, any peer will
see another as defunct, leading to peer list atrophy. This
allows us random retries.
In addition, we need to cleanup peers after a while, we quickly
accumulate hundreds of dead peers over time. This should be
tracked by a different issue however.

* Allow TLS for Wallet APIs
This PR adds an optional support of TLS for wallet APIs. Only PKCS12 format is supported, will address .pem support in next PR and provide some documentation.
Address #1425
According to rfc2616[1], the response from a server to a request with
bad credentials should be a 401 instead of a 403. Grin does not have
the concept of identities so it does not actually recognize a user
request with bad credentials.
