clang_Type_getTemplateArgument
Note that these functions don't handle variadic templates -- see tests.

This commit improves libclang to report the error condition when
CXTranslationUnit can not be created because of a stale PCH file. This allows
the caller, for example, to rebuild the PCH file and retry the request.
There two are APIs in libclang that return a CXTranslationUnit and don't
support reporting detailed errors (the only error condition is a NULL result).
For these APIs, a second, superior, version is introduced --
clang_createTranslationUnit2 and clang_parseTranslationUnit2. These functions
return a CXTranslationUnit indirectly and also return an error code. Old
functions are still supported and are nothing more than convenience wrappers
that ignore extended error codes.
As a cleanup, this commit also categorizes some libclang errors in the
functions I had to modify anyway.

the build
When Clang loads the module, it verifies the user source files that the module
was built from. If any file was changed, the module is rebuilt. There are two
problems with this:
1. correctness: we don't verify system files (there are too many of them, and
stat'ing all of them would take a lot of time);
2. performance: the same module file is verified again and again during a
single build.
This change allows the build system to optimize source file verification. The
idea is based on the fact that while the project is being built, the source
files don't change. This allows us to verify the module only once during a
single build session. The build system passes a flag,
-fbuild-session-timestamp=, to inform Clang of the time when the build started.
The build system also requests to enable this feature by passing
-fmodules-validate-once-per-build-session. If these flags are not passed, the
behavior is not changed. When Clang verifies the module the first time, it
writes out a timestamp file. Then, when Clang loads the module the second
time, it finds a timestamp file, so it can compare the verification timestamp
of the module with the time when the build started. If the verification
timestamp is too old, the module is verified again, and the timestamp file is
updated.

Uses of clang_getSpellingLocation should eventually move to calling
clang_getFileLocation, and clang_getSpellingLocation should do what
its name represents and actually point at the 'spelling' location, e.g.
inside a macro definition if the spelling of a token came from that.

The implementation also includes a Relax NG schema and tests for the schema
itself. The schema is used in c-index-test to verify that XML documents we
produce are valid. In order to do the validation, we add an optional libxml2
dependency for c-index-test.

The only caveat is renumbering CXCommentKind enum for aesthetic reasons -- this
breaks libclang binary compatibility, but should not be a problem since API is
so new.
This also fixes PR13372 as a side-effect.

For testing, c-index-test now has even more output:
* HTML rendering of a comment
* comment AST tree dump in S-expressions like Comment::dump(), but implemented
* with libclang APIs.

given a cursor pointing to a C++ method call or an ObjC message,
returns non-zero if the method/message is "dynamic", meaning:
For a C++ method: the call is virtual.
For an ObjC message: the receiver is an object instance, not 'super' or a
specific class.

attached to a declaration in the completion string.
Since extracting comments isn't free, a new code completion option is
introduced.
A new code completion option that enables including brief comments
into CodeCompletionString should be a, err, code completion option.
But because ASTUnit caches global declarations during parsing before
even completion consumer is created, the option is duplicated as a
translation unit option (in both libclang and ASTUnit, like the option
to cache code completion results).

Most of the times there is only one range for the complete spelling but for
objc methods and objc message expressions, there are multiple pieces for each
selector identifier.

the new Objective-C NSArray/NSDictionary/NSNumber literal syntax.
This introduces a new library, libEdit, which provides a new way to support
migration of code that improves on the original ARC migrator. We now believe
that most of its functionality can be refactored into the existing libraries,
and thus this new library may shortly disappear.
