A recurring problem with the Q_NAMESPACE macro is that it declares
an object (staticMetaObject) in the surrounding namespace. That
object lacks any export/import qualification to make it usable
with shared libraries.
Introduce therefore another macro to work around this issue, allowing
the user to prefix the object with an exporting macro, f.i. like this:
Q_NAMESPACE_EXPORT(Q_CORE_EXPORT)
The old macro can simply then be rewritten in terms of this new one,
supplying an empty export macro.
Note that NOT passing an argument to a macro expecting one is well
defined behavior in C99 -- the macro will expand an empty token.
Of course, MSVC doesn't like this and emits warnings. As a
workaround, use a variadic macro.
[ChangeLog][QtCore] Added the new Q_NAMESPACE_EXPORT macro. It
can be used just like Q_NAMESPACE to add meta-object information
to a namespace; however it also supports exporting of such
information from shared libraries.
[ChangeLog][Potentially Source-Incompatible Changes] Prefixing
Q_NAMESPACE with an export macro may no longer work. Use the new
Q_NAMESPACE_EXPORT macro for that use case.

Information about header files is cached by qmake. The key is the
filename of the #include directive. For system includes (<stdio.h>) this
is unique, according to the search order in INCLUDE_PATH.
For local includes, given as "foo.h", there may be name collisions. Usually a
compiler first searches in the directory of the current file (stored in the
sourceDir variable), and only in case of a miss the INCLUDE_PATH is
considered.
The dependency generation now distinguishes local header files by their full
relative path. This is implemented by forcing the use of the full relative
path as key into the SourceFiles data structure if the flag try_local is set.

A macro name ending in R might expand to a string; if this precedes a
string constant, we're juxtaposing the strings. My first parser for
raw strings would mistake it for a raw string instead, ignoring the
part of the identifier before R. Re-worked the exploration of what
came before the string to catch these cases, too.
The backwards parsing would also allow any messy jumble of [RLUu8]* as
prefix for the string; but in fact R must (if present) be last in the
prefix and *it* can have at most one prefix, [LUu] or u8. Anything
else is an identifier that happens to precede the string. Reworked
the parsing to allow only one prefix and not treat R specially unless
it's immediately (modulo BSNL) before the string's open-quotes.
Add link to the cppreference page about string literals, on which the
grammar now parsed is based.
Added a test for the issue this addresses.
Verified that this fails on 5.6, dev and 5.9 without the fix.
Expanded the existing test to cover R-with-prefix cases.

Can't sensibly test unless the compiler does support raw strings,
since any test that would catch qmake's (prior) inability to parse raw
strings would necessarily confuse the C++ compiler in the same way.
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.

A loop to skip space and comments was meant to break on anything else
but would have not broken on a division operator (where it should) due
to it getting caught in the check for a comment-start, without falling
back suitably when it didn't complete that check.
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.

in most cases, it actually means normalizePath() (because the file name is
used with qt i/o functions afterwards).
this affects QMakeLocalFile::local() as well, so many not immediately
obvious places are affected as well.
there was also one case of fixPathToTargetOS() falling into this category.
this is mostly a no-op, as the qt functions are agnostic to the path
separator.
in some other cases (in particular in the vcproj generator), it actually
means fixPathToTargetOS().
this is mostly a no-op as well, as the two functions are equal except on
msys anyway.
in the <meta file>FileName() functions, the use of a fixPath*() function
is bogus in the first place - fileFixify() already does
fixPathToTargetOS(), and this is correct when the file name is used
verbatim in a make command (which it is). otherwise it's irrelevant.

Assume that C and C++ headers found in system paths will not change,
so we don't need to tell Make about them, nor do we need to scan their

The previous qmake behavior matched gcc's -M switch; it now matches
the -MM switch:
-M Instead of outputting the result of preprocessing, output a
rule suitable for make describing the dependencies of the
main source file.
-MM Like -M but do not mention header files that are found in
system header directories, nor header files that are
included, directly or indirectly, from such a header.
This goes hand-in-hand with our use of -isystem to pass system paths
