[Bug 1828215] Re: openssl ca -spkac output regressed

[Dimitri John Ledkov]

Run through CA setup, and ended up corrupting my terminal due to binary
output using the current bionic-updates 1.1.1-1ubuntu2.1~18.04.1

Upgraded to:
# dpkg-query -W openssl libssl1.1
libssl1.1:amd64	1.1.1-1ubuntu2.1~18.04.2
openssl	1.1.1-1ubuntu2.1~18.04.2

Rerun the procedure and ended up with text output:
...

0I0+Aaqph4FbJf8qlzeViPcb6P0MRdNr+6eLedKcDLTJHFWAGIn0ahKa
-----END CERTIFICATE-----
Data Base Updated

All is good.

Bug description:
  [Impact]

   * openssl command line utility option parsing has regressed in
  1.1.0i+ and produces binary output, where text output is expected,
  breaking applications that parse that.

  [Test Case]

  Setup CA:
  $ apt install openssl
  $ mkdir -p  demoCA/private demoCA/newcerts
  $ touch demoCA/index.txt
  $ echo 01 > demoCA/serial

  $ openssl req -new -x509 -days 365 -newkey rsa:4096 -keyout
  demoCA/private/cakey.pem -out demoCA/cacert.pem

  # Use password test
  # Accept defaults for all other settings

  $ openssl req -new -days 365 -newkey rsa:4096 -keyout
  demoCA/sslkey.pem -out demoCA/sslcert.pem

  Generate regular request / key:
  # Use password test
  # Set common name to: example.com
  # Accept defaults for all other settings

  Generate spkac request:
  $ openssl spkac -key demoCA/sslkey.pem -out demoCA/sslcert.spkac
  $ cat <<EOF >>demoCA/sslcert.spkac 
  countryName=AU
  stateOrProvinceName=Some-State
  organizationName=Internet Widgits Pty Ltd
  commonName=example.com
  EOF

  Sign spkac request:
  $ echo test | openssl ca -passin stdin -batch -spkac demoCA/sslcert.spkac -startdate 190121130654Z

  Expected: pure text output
  Unexpected: binary output for the signed cert

  
   Currently produces binary goop.

   Should produce PEM format Base64 encoded certificate data in a block surrounded
   with BEGIN/END certificate.

  [Regression Potential]

   * This is a regression in cosmic and up, and impeding regression in
  bionic with the upcoming 1.1.1 SRU. A bugfix exists upstream.
