    Reindent unix/dialog.c.

    Large chunks of the GTK setup code had a 2-space indent for some
    reason, in place of the usual 4-space in this code base. I've been
    meaning to sort it out for ages, because it makes it hard to have a
    single set of editor settings suitable for the whole code base.

    GTK: remove 'entrysig' in struct uctrl.

    The only *use* of it was removed in commit 6a743399b03e3d6, where
    instead of blocking the GTK signal that caused a string to be
    overwritten, I switched to making a temporary copy of the string. But
    I didn't notice that the declaration and assignments could be cleaned
    up too.

    New function dlg_editbox_select_range.

    This manipulates the selection inside an edit box, to select a
    specific range of characters in the contained text. The idea is that
    you can use it as a means of error highlighting, if the user has
    entered something invalid in that edit box and you want to draw their
    attention to the specific location of the part you're unhappy with.

    A few more ptrlen functions.

    ptrlen_contains and ptrlen_contains_only are useful for checking that
    a string is composed entirely of certain characters, or avoids them.

    ptrlen_end makes a pointer to the byte just past the end of the
    specified string. And it can be used with make_ptrlen_startend, which
    makes a ptrlen out of two pointers instead of a pointer and a length.

    Routines for %-encoding and %-decoding.

    These make a good storage format for mostly-textual data in
    configuration, if it can't afford to reserve any character as a
    delimiter. Assuming very few characters need to be escaped, the space
    cost is lower than base64, and also you can read it by eye.

    Certificate trust scope: change to a boolean-expression system.

    This replaces the previous placeholder scheme of having a list of
    hostname wildcards with implicit logical-OR semantics (if any wildcard
    matched then the certificate would be trusted to sign for that host).
    That scheme didn't allow for exceptions within a domain ('everything
    in example.com except extra-high-security-machine.example.com'), and
    also had no way to specify port numbers.

    In the new system, you can still write a hostname wildcard by itself
    in the simple case, but now those are just atomic subexpressions in a
    boolean-logic domain-specific language I've made up. So if you want
    multiple wildcards, you can separate them with || in a single longer
    expression, and also you can use && and ! to impose exceptions on top
    of that.

    Full details of the expression language are in the comment at the top
    of utils/cert-expr.c. It'll need documenting properly before release,
    of course.

    For the sake of backwards compatibility for early adopters who've
    already set up configuration in the old system, I've put in some code
    that will read the old MatchHosts configuration and automatically
    translate it into the equivalent boolean expression (by simply
    stringing together the list of wildcards with || between them).
