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.

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.

Offsets can be get wrong because of the utf8 <-> utf16 differences. Line
and columns are not that sensitive to it.

Prepare the move of the semantic highlighting to the clang back end. We
have it under tests too so it should be quite easy to make changes or
corrections.

Diagnostics are now moved to the clang backend process. Fixits are
supported too.
