bugzilla: add XMLRPC interface.

Add support for access to Bugzilla via the XMLRPC interface.

This requires a single username and password used to log in to Bugzilla,
plus the URL of the Bugzilla installation. Commit messages are added to
bugs as before, but security only permits them to be added as the
username used to log in.

Simple commands:

  $ echo foo
  foo
  $ printf 'oh no'
  oh no (no-eol)
  $ printf 'bar\nbaz\n' | cat
  bar
  baz

Multi-line command:

  $ foo() {
  >     echo bar
  > }
  $ foo
  bar

Regular expressions:

  $ echo foobarbaz
  foobar.* (re)
  $ echo barbazquux
  .*quux.* (re)

Globs:

  $ printf '* \\foobarbaz {10}\n'
  \* \\fo?bar* {10} (glob)

Literal match ending in " (re)":

  $ echo 'foo (re)'
  foo (re)

Exit code:

  $ (exit 1) 
  [1]
