xmlCtxtReadFile doesn't work with literal IPv6 URLs
https://bugzilla.gnome.org/show_bug.cgi?id=694185 RedHat Bug 624626 discusses the new behavior of libxml regarding brackets around IPv6 addresses. In earlier versions such as 2.6.27, uri.c stripped the brackets (e.g. uri->server == "fdf2:1e39:73d1:934e::119"); in the current version it returns IPv6 addresses with brackets intact (e.g. uri->server == "[fdf2:1e39:73d1:934e::119]"). Thus in 2.9.0, xmlCtxtReadFile() has a problem when it is passed a URL containing a literal IPv6 address. xmlCtxReadFile() and its subroutines pass uri->server unchanged to getaddrinfo(), which doesn't recognize a bracketed IPv6 address, so the read fails. This strips the [ and ] from IPv6 addresses allowing getaddrinfo() to work properly with such URIs.
