Java-style iterators are slower than STL-style ones, so
they should not be used in library code.
Replaced them with C++11 range-for, STL iterators or, in
one case, qDeleteAll().
In one case, avoid a double hash lookup by using erase(it)
instead of remove(it.key()), which we can now do without
detaching, due to the new erase() taking const_iterator.

In VcprojGenerator::collectDependencies(), a temporary QLinkedList
is created, then iterated over. There's no reason to use a node-
based container here: no references are taken, no erases happen,
esp. not in the middle...
Port to QVector instead and reserve it, since the maximum size is
known ahead of time, and the lifetime of the container is very
short.
Since the loop iterating over the linked list needed touching
anyway, port directly to C++11 range-for.

When building QNX on MS-Windows, make magically adds the Msys root as
prefix to variables whose values look like paths; this applies to both
environment variables and variables given values on the command-line.
When we don't actually want to install under the Msys root, this is
unwelcome "help". So (for MinGW's make) support a magic prefix of our
own, @msyshack@, that'll make a path value for INSTALL_ROOT not look
like a path to make; we can then strip it off when we come to use it.

this change is slightly backwards-incompatible, as invoking

This even applies (in test app code) to any #if-ery around the raw
string, since tokenization happens before preprocessor directives are
resolved. So the #if-ery on Q_COMPILER_RAW_STRINGS has to be in
tst_qmake.cpp, not the test app it builds.

When looking for the keyword in a preprocessor directive, we were
checking for non-word characters to find its end. If that check
failed (i.e. we had a word character) we would then check for EOL
(which necessarily failed, on a word character). That made no sense.
However, we genuinely have no interest in a directive with nothing
after the keyword, so do check for EOL after the loop (once we've
skipped spaces after the keyword).
The loop itself was made needlessly complicated by, on finding the end
of the keyword, skipping over later space inside the loop. Moved this
outside the loop.

Managed to contrive a suitably twisted change to findDeps test to
reveal the bug; broken previously, now fixed. Not ideal, as it relied
on another bug to fail previously - backslash-newline shouldn't end a
preprocessing directive line - but it should still pass once that's
fixed, too. Exercising a bug in qmake usually involves code that
won't compile anyway, making it tricky to write a test that reveals
the bug but that passes once it's fixed.
