mq: smarter handling of plain headers

6333412245ec and 5ccced6eab0b fixed issue4453 with a simple insertplainheader
function that fixed the regression but didn't make the implementation more
stable.

Now we introduce plain header handling similar to how we handle hg patches. The
whole header is scanned for fields to update while determining the best
position for inserting the field if it is missing. It also makes sure there is
an empty line between headers and body.

    This tests for edge cases in url.URL's parsing algorithm. Most of
    these aren't useful for documentation purposes, so they aren't
    part of the class's doc tests.

    Query strings and fragments:

    >>> url('http://host/a?b#c')
    <url scheme: 'http', host: 'host', path: 'a', query: 'b', fragment: 'c'>
    >>> url('http://host/a?')
    <url scheme: 'http', host: 'host', path: 'a'>
    >>> url('http://host/a#b#c')
    <url scheme: 'http', host: 'host', path: 'a', fragment: 'b#c'>
    >>> url('http://host/a#b?c')
    <url scheme: 'http', host: 'host', path: 'a', fragment: 'b?c'>
    >>> url('http://host/?a#b')
    <url scheme: 'http', host: 'host', path: '', query: 'a', fragment: 'b'>
    >>> url('http://host/?a#b', parsequery=False)
    <url scheme: 'http', host: 'host', path: '?a', fragment: 'b'>
    >>> url('http://host/?a#b', parsefragment=False)
    <url scheme: 'http', host: 'host', path: '', query: 'a#b'>
    >>> url('http://host/?a#b', parsequery=False, parsefragment=False)
    <url scheme: 'http', host: 'host', path: '?a#b'>

    IPv6 addresses:

    >>> url('ldap://[2001:db8::7]/c=GB?objectClass?one')
    <url scheme: 'ldap', host: '[2001:db8::7]', path: 'c=GB',
         query: 'objectClass?one'>
    >>> url('ldap://joe:xxx@[2001:db8::7]:80/c=GB?objectClass?one')
    <url scheme: 'ldap', user: 'joe', passwd: 'xxx', host: '[2001:db8::7]',
         port: '80', path: 'c=GB', query: 'objectClass?one'>

    Missing scheme, host, etc.:

    <url scheme: 'http', host: 'x.com', query: 'arg=/foo'>
    >>> url('http://joe:xxx@/foo')
    <url scheme: 'http', user: 'joe', passwd: 'xxx', path: 'foo'>

    Just a scheme and a path:

    >>> url('mailto:[e-mail]')
    <url scheme: 'mailto', path: '[e-mail]'>
    >>> url('a:b:c:d')
    <url path: 'a:b:c:d'>
    >>> url('aa:bb:cc:dd')
    <url scheme: 'aa', path: 'bb:cc:dd'>

    SSH examples:

    >>> url('ssh://joe@host//home/joe')
    <url scheme: 'ssh', user: 'joe', host: 'host', path: '/home/joe'>
    >>> url('ssh://joe:xxx@host/src')
    <url scheme: 'ssh', user: 'joe', passwd: 'xxx', host: 'host', path: 'src'>

    >>> url('ssh://joe@host')
    <url scheme: 'ssh', user: 'joe', host: 'host'>
    >>> url('ssh://host')
    <url scheme: 'ssh', host: 'host'>
    >>> url('ssh://')
    <url scheme: 'ssh'>
    >>> url('ssh:')
    <url scheme: 'ssh'>

    Non-numeric port:

    >>> url('http://example.com:dd')
    <url scheme: 'http', host: 'example.com', port: 'dd'>
    >>> url('ssh://joe:xxx@host:ssh/foo')
    <url scheme: 'ssh', user: 'joe', passwd: 'xxx', host: 'host', port: 'ssh',
         path: 'foo'>

    Bad authentication credentials:
