it is sometimes desirable to override values from the mkspec without
modifying (or wrapping) the spec itself. linux distributors do this on a
regular basis.
so far, we'd pick up CFLAGS, etc. from the environment, in a somewhat
autoconf-like fashion. however, over time, this approach proved
problematic: the concept doesn't mix particularly well with mkspecs to
start with, is unexpected (and therefore causes frustration), and
doesn't mix well with cross-building (at least the way it was realized).
ironically, it was implemented this way (quite a while ago) upon my
explicit request ...
the new mechanism uses explicit variable manipulations on the configure
command line, just like qmake itself understands. as it happens, this is
again quite similar to autoconf-generated configure scripts. however,
this time around we don't pretend to be actually autoconf-like, so we
also don't try to map any variable names (some of which have different
semantics anyway).
this commit also eliminates the last use of the QMakeVar() function,
so delete it and the underlying infrastructure.

it's really a bit weird that the windows configure has more options to
configure unix features than the unix one, even if some are just
workarounds for missing auto-detection.
unlike in configure.exe itself, -posix-iconv is now also understood for
symmetry with -gnu-iconv and -sun-iconv.

- remove the redundantly listed -no-* options and indicate the defaults
differently
- completely regroup the options into somewhat logical sections

These arguments were nonsensical, as they would lead to every single Qt
module linking to those libraries. This was probably some left-over from
old times, when Qt was just a single library.

Since the system proxies are on by default now then we turn off
libproxy support by default so that there is no risk of a conflict
occurring.
For instance on Linux, it is possible that libproxy indirectly causes
KDE 4 libraries to be loaded which will cause a conflict with the Qt 5
libraries. Therefore we turn it off by default, since the system
proxy setting is the overall better one to have.
[ChangeLog][Important Behavior Changes][QtNetwork] libproxy is now
turned off by default. Configure with -libproxy in order to enable it
again.

By changing the system proxies option default to being on, we
set it to be the more natural default setting. This is down
to the fact that people tend to assume that this is already
the default option.
[ChangeLog][Important Behavior Changes][QtNetwork] Proxies from
system settings will now be used by default. Configure with
-no-system-proxies to disable.
