A lot of code in Qt uses VAR=1 for enabling or disabling some feature
or other, ignoring qEnvironmentVariableIsSet(), which was added for
that purpose. Other code actually reads numerical values from
environment variables. For both use-cases, provide a non-throwing,
non-memory-allocating way to get the numerical (int) value of an
environment variable, complementing qEnvironmentVariableIs{Set,Empty}().
[ChangeLog][QtCore] Added qEnvironmentVariableIntValue().

The existing tst_qgetputenv shows that qputenv with an empty value
doesn't lead to the same result on Windows and on Unix, and there was
no way to fully delete an env var on Unix (which is needed for some
env vars where not-set and empty are different, such as TZ,
see `man tzset`).
This is also why qglobal has qEnvironmentVariableIsSet() vs
qEnvironmentVariableIsEmpty(), on the getter side.
Qt4's ifdefs around unsetenv in qapplication_x11.cpp show that this is
needed within Qt too (although this particular startup notification code
has to be re-imported into Qt5 still).

These functions are a faster version of {,!}qgetenv().is{Null,Empty}(),
a common pattern in Qt code.
Their main advantage is that they don't need to allocate memory, so
they can be used in noexcept functions, or dynamic initialisation of
namespace-scope statics, because throwing in these contexts invokes
std::terminate().

Qt 5.0 beta requires changing the default to the 5.0 API, disabling
the deprecated code. However, tests should test (and often do) the
compatibility API too, so turn it back on.

As in the past, to avoid rewriting various autotests that contain
line-number information, an extra blank line has been inserted at the
end of the license text to ensure that this commit does not change the
total number of lines in the license header.

These comments were mostly empty or inaccurate. Appropriate naming of
tests and appropriate placement of tests within the directory tree
provide more reliable indicators of what is being tested.

qttest_p4.prf was added as a convenience for Qt's own autotests in Qt4.
It enables various crufty undocumented magic, of dubious value.
Stop using it, and explicitly enable the things from it which we want.
