Instead, always write into a unique temporary directory in
QDir::tempPath().
Where applicable, read the test source from files instead of first
writing the file.
Some clean ups in test_codegen*.

By lexing the first token after a macro call (meaning: the token after
the closing parenthesis (which was passed to handleFunctionLikeMacro
which in turn pushed it back into the token buffer)), a token buffer
might be popped, which unblocks the macro that generated the actual
param pack. The effect was that if this happens in the expansion of a
recursive macro (with parameters!), the preprocessor ended up in an
infinite loop.

Doing so resulted in an incorrect position for the EOF token when the
preprocessed output would be parsed. That in turn leads to incorrect
insertion positions for refactoring actions.
This is especially true when a file contains only preprocessor
directives: the EOF token would point to line 1 column 1, which is
usually not the place where code should be inserted.

Summary of most relevant items:
- Preprocessor output format change. No more gen true/false. Instead
a more intuitive and natural expansion (like from a real compiler) is
performed directly corresponding to the macro invocation. Notice that
information about the generated tokens is not lost, because it's now
embedded in the expansion section header (in terms of lines and columns
as explained in the code). In addition the location on where the macro
expansion happens is also documented for future use.
- Fix line control directives and associated token line numbers.
This was not detected in tests cases because some of them were
actually wrong: Within expansions the line information was being
considered as originally computed in the macro definition, while
the desired and expected for Creator's reporting mechanism (just
like regular compilers) is the line from the expanded version
of the tokens.
- Do not allow for eager expansion. This was previously being done
inside define directives. However, it's not allowed and might
lead to incorrect results, since the argument substitution should
only happen upon the macro invocation (and following nested ones).
At least GCC and clang are consistent with that. See test case
tst_Preprocessor:dont_eagerly_expand for a detailed explanation.
- Revive the 'expanded' token flag. This is used to mark every token
that originates from a macro expansion. Notice, however, that
expanded tokens are not necessarily generated tokens (although
every generated token is a expanded token). Expanded tokens that
are not generated are those which are still considered by our
code model features, since they are visible on the editor. The
translation unit is smart enough to calculate line/column position
for such tokens based on the information from the expansion section
header.
- How expansions are tracked has also changed. Now, we simply add
two surrounding marker tokens to each "top-level" expansion
sequence. There is an enumeration that control expansion states.
Also, no "previous" token is kept around.
- Preprocessor client methods suffered a change in signature so
they now receive the line number of the action in question as
a paramater. Previously such line could be retrieved by the client
implementation by accessing the environment line. However, this
is not reliable because we try to avoid synchronization of the
output/environment lines in order to avoid unnecessary output,
while expanding macros or handling preprocessor directives.
- Although macros are not expanded during define directives (as
mentioned above) the preprocessor client is now "notified"
when it sees a macro. This is to allow usage tracking.
- Other small stuff.
This is all in one patch because the fixes are a consequence
of the change in preprocessing control.

Generated tokens do not have a position in any source file, so not try
to indent them. Previously, the 'source' used was the scratch buffer,
which would not contain newlines, so the indent depth would be the
length of the scratch buffer at that point.

This rewrite fixes a couple of issues with the pre-processor. It now
supports:
- macros in macro bodies
- stringification of parameters [cpp.stringize]
- the concatenation operator [cpp.concat]
- #include MACRO_HERE
- defined() inside macro bodies used in pp-conditions.
