The included patch from upstream fixes the issue described here:
https://bugreports.qt.io/browse/QTBUG-48321
The backing store of certain widgets was being improperly invalidated,
leading to display bugs in, e.g. VLC.
This patch is included in Qt 5.6, so we should remove it when we
upgrade.
Multitarget option builds gdb with support for all targets. That's
similar to gdb-multiarch package in Ubuntu or gdb with multitarget
USE-flag in Gentoo.
Nobody seems to have noticed this (except @Profpatsch) that options with
a "package" type do not get included in the manual.
So debugging this was a bit more involving because while generating the
manual there is an optionList' attribute built from the collected
attributes of all the option declarations.
Up to that point everything is fine except if it comes to
builtins.toXML, where attributes with { type = "derivation" } won't get
included, for example see here:
nix-repl> builtins.toXML { type = "derivation"; foo = "bar"; }
"<?xml version='1.0' encoding='utf-8'?>\n<expr>\n <derivation>
<repeated />\n </derivation>\n</expr>\n"
nix-repl> builtins.toXML { type = "somethingelse"; foo = "bar"; }
"<?xml version='1.0' encoding='utf-8'?>\n<expr>\n <attrs>
<attr name=\"foo\">\n <string value=\"bar\" />\n </attr>
<attr name=\"type\">\n <string value=\"somethingelse\" />
</attr>\n </attrs>\n</expr>\n"
The following function in libexpr/eval.cc (Nix) is responsible for toXML
dropping the attributes:
bool EvalState::isDerivation(Value & v)
{
if (v.type != tAttrs) return false;
Bindings::iterator i = v.attrs->find(sType);
if (i == v.attrs->end()) return false;
forceValue(*i->value);
if (i->value->type != tString) return false;
return strcmp(i->value->string.s, "derivation") == 0;
}
So I've renamed this now to "package" which is not only more consistent
with the option type but also shouldn't cause similar issues anymore.
Tested this on base of b60ceea, because building the dependencies on
recent libc/staging changes on master took too long.

We don't want to build all those things along with the manual, so that's
what the defaultText attribute is for.
Unfortunately a few of them were missing, so let's add them.

It seemed very fine on Hydra before it was cancelled due to glibc rebuild,
in particular the nixpkgs unstable job succeeded except for
bootstrap-tarball tests which should be fine after ee994dfae6.
Therefore, let's avoid another mass rebuild by merging now when we don't
have binaries for master anyway.
I assume there's not much use for it during bootstrapping.
This fixes them as well, as curl was compiled against libnghttp2 but the
lib wasn't copied to the bootstrap tools.
