globbing supports character classes now and ^EN string building construct to escape glob patterns

 * globbing is fnmatch(3) compatible, now on every supported platform.
 * which means that escaping of glob patterns is possible now.
   ^ENq has been introduced to ease this task.
 * This finally allows you to pass unmodified filenames to EB.
   Previously it was impossible to open file names containing glob wildcards.
 * this was achieved by moving from GPattern to GRegex as the underlying
   implementation.
 * The glob pattern is converted to a regular expression before being
   compiled to a GRegex.
   This turned out to be trickier than anticipated (~140 lines of code)
   and has a runtime penalty of course (complexity is O(2*n) over the
   pattern length).
   It is IMHO still better than the alternatives, like importing
   external code from libiberty, which is potentially non-cross-platform.
 * Using GRegex also opens the potential of supporting brace "expansions"
   later in the form of glob pattern constructs
   (they won't actually expand but match alternatives).
 * is_glob_pattern() has been simplified and moved to Globber::is_pattern().
   It makes sense to reuse the Globber class namespace instead of using
   plain functions for functions working on glob patterns.
 * The documentation has a new subsection on glob patterns now.
 * Testsuite extended with glob pattern test cases

 Features:
- * Glob patterns: GPattern, currently used in glob.cpp is
-   not very powerful and does not allow character classes or
-   escaping of glob patterns.
-   Unfortunately glob(3) or fnmatch(3) are POSIX-only, so
-   using them is not an option and does not resolve the
-   escaping issue in general.
-   We'd either have to import fnmatch(3) via Libiberty on non-POSIX
-   platforms, OR convert glob patterns to regexps and use
-   GRegEx as the underlying matcher.
-   The latter has the advantage that we could also provide
-   brace "expansion" usually performed by POSIX shells.
- * Document how to escape magic characters in glob patterns.
-   There should be a string building construct to escape
-   glob characters (e.g. ^EN)
  * Auto-indention could be implemented via context-sensitive
    immediate editing commands similar to tab-expansion.
    Avoids having to make LF a magic character in insertion
