[BBDB] ChangeLog 2022-03-26 (increase version number, snarf vCards)

I have pushed several changes for BBDB, see the ChangeLog below.

- BBDB now uses user-error where appropriate

- For Gnus bbdb-message-header now considers the parent summary buffer
  (Bug#54423).

- I have increased the version number to 3.2.2 so that recent changes
  including the above become visible in GNU Elpa

- I have added yet experimental code for snarfing vCards.  Recently I
  had to import the content of several vCards into BBDB.  I could spent
  my time either by doing this "by hand" or trying to automate this.  So
  I did the latter.  Yet my real-world examples for testing the code
  were limited.  It is my understanding that RFC 6350 is one thing and
  implementations of the vCard standard by other applications is a
  separate story.  So I tried to make the snarfing code as
  fault-tolerant and flexible as possible (based on the limited set of
  vCards with which I could test the code).

  Currently the code snarfs the n, fn, adr, nickname, email, tel, org,
  uid, url, and note properties, and it considers the pref and type
  parameters.  The parsing of vCards happens in
  bbdb-snarf-vcard-property.  It can still be improved.  The remaining
  functions then use it to populate the BBDB record.  The modular design
  of snarfing rules should help with customizing and extending this.
  The user commands for this are bbdb-snarf-vcard and
  bbdb-snarf-vcard-buffer.

  Also, I added a new function bbdb-snarf-sanity-check to all snarfing
  rules.  Probably, it can likewise still be improved.

  Suggestions and comments welcome!
