- added more error log messages when proxy-protocol is used

Log message:
Update to 20220901. From the changelog:

- fixed randombytes(), uses getentropy() and /dev/urandom where
  getentropy() does not exist

Log message:
Apply upstream commit 0cb7bb4 to fall back to /dev/urandom on systems
where getentropy() is not present. Bump PKGREVISION.

Log message:
Update to 20220114. From the changelog:

- added "experimental" support for delayed encryption (option -nN)
- add tlswrapper-smtp (STARTTLS support for old inetd-style SMTP servers)

Log message:
Fix build on BSDs and Solarish.

Log message:
Add tlswrapper, an UCSPI/inetd-style TLS encryption wrapper.

tlswrapper is an TLS encryption wrapper between remote client and local
program prog. Systemd.socket/inetd/tcpserver/... creates the server
connection, tlswrapper encrypts/decrypts data stream and reads/writes
data from/to the program prog as follows:

Internet <--> systemd.socket/inetd/tcpserver/... <--> tlswrapper \ 
<--> prog

By running separate instance of tlswrapper for each TLS connection, a
vulnerability in the code (e.g. bug in the TLS library) can't be used to
compromise the memory of another connection.

To protect against secret-information leaks to the network connection
(such Heartbleed) tlswrapper runs two independent processes for every
TLS connection. One process holds secret-keys and runs secret-keys
operations and second talks to the network. Processes communicate with
each other through UNIX pipes.
