606d41187c Clang: Prepare for multi-threading
* Make the necessary data implicitly shared since it might get
  accessed/modified from two different threads with follow-up changes.
  This applies for UnsavedFiles/UnsavedFile and ProjectPart::arguments().

* Avoid returning references.

36e7f4541f Clang: Pass on file paths with native separators
libclang 3.8 seems to be sensitive to file paths separators [1]. On Windows,
this led to not updated document annotations and/or crashes after reparsing.

When passing file paths to libclang, convert to native separators.
When getting file paths from libclang, convert back.

This handles:
 * main file path
 * file paths of the unsaved files
 * -I<DIR> arguments, the resource path (for builtins) and the paths to the
   wrapped qt headers
 * included header files from libclang
 * source locations from libclang

Also, minimize the conversion in SourceLocation to a minimum by making
filePath() lazy.

05c1efd8ef Clang: Fix dot-arrow-correction for not-yet-parsed unsaved content
The issue was re-producible with e.g.:

    void g()
    {
        // Type 'foo.' as fast as possible in the next line

    }

This led to "foo->" with completion results as if there was no "foo." at
all in that line.

We relied on a correct position for
translationUnit.sourceLocationAtWithoutReparsing(), but the just typed
characters were not yet reparsed. And we do not want to reparse at that
point since takes too long. We already determine the utf8 position for
the dot character, so simply use that instead.

This completes commit 17c1325cc4.

17c1325cc4 Clang: Fix dot to arrow correction
The position of the dot character was determined on an outdated
translation unit.

We queried the translation unit for the source location of the dot
character, but apparently clang_codeCompleteAt() does not update the
source locations for the translation unit. And we do not want to reparse
since this is expensive. Thus, determine the byte position manually by
scanning over the document until the right line/column is reached.

8d6549fa74 Clang: Correct member access operator if possible
1 struct Foo { int member; };
 2 void f(Foo *foo)
 3 {
 4     foo.<REQUEST COMPLETION> // correct '.' to '->' and provide results
 5 }

The preferred approach would be to check if "foo" in line 4 is of
pointer type, but there is no suitable cursor (only CompoundStmt) at
that position since the code is usually not yet parsed and thus invalid.

Thus, just run the completion as is. If there are not any results for a
dot completion, re-run the completion with "." exchanged by "->". This
approach is inherently slower than the preferred approach implemented in
the built-in code model.

The following rare cases are not handled:

 1) Requesting completion after white space:
      Works: foo.<COMPLETE HERE>
      Fails: foo. <COMPLETE HERE>

 2) Opening a file and requesting completion (ctrl+space) without prior
    editing. No editing before triggering completion means that no
    unsaved file is generated on the backend side, which is a
    requirement for the correction.

f2b7371af1 Clang: Reparse only if files are changed
Includes are now watched by a file watcher. Unsaved file changes are
watched too. If they are changed the translation units which depend on
them are set to a state which require a reparse. Later the diagnostics
of this units are collected and send back to creator.

b3113bbbc6 Clang: Reparse always before you complete the code
There are two ways to hot fix the dependency problem. First version is to
disable the caching(not the preamble) but it is triggering bugs. Second 
version is to enable caching and reparse before every complete. I opted
for the second version because it is the commonly used path for most
implementations. Later we have to minimize the reparse calls but for that 
we need the cooperation of editor.
