Patch extracted from a larger one by the PaX team. I added the testcases
and tightened error handling a bit.

[Sanitizer] move all the rest re-implementations of libc functions from ASan runtime to common sanitizer runtime

* Converted comments to use \brief to provide summaries;
* Fixed uses of \arg that should be \p;
* Fixed \param [in] [out] to \param [in,out];
* Made minor formatting fixes.

not \arg ParameterName (which should be used only when documenting that
parameter, not when referring to it from elsewhere).

* Escaped @ symbols that shouldn't be interpreted by Doxygen;
* Deleted \param documentation for function parameters that no longer exist;
* Fixed parameter names in \param Doxygen commands;
* Fixed some broken formatting.

on ASTContext::CreateTypeSourceInfo that duplicated information from the
(more complete) version in ASTContext.h.

* Add \brief to produce a summary in the Doxygen output;
* Add missing parameter names to \param commands;
* Fix mismatched parameter names for \param commands;
* Add a parameter name so that the \param has a target.

* Removed \param comments for parameters that no longer exist;
* Fixed a "\para" typo to "\param";
* Escaped @, # and \ symbols as needed in Doxygen comments;

* Added/tidied \brief summaries;
* Escaped # as needed for Doxygen;
* Drive-by: Fixed a rogue line > 80 columns.

* Add parameter names to various \param commands;
* Ensure that \brief summaries are followed by blank lines where needed to
  prevent subsequent text being merged into the summary;
* Mark code examples with \code...\endcode so that they're appropriately
  formatted by Doxygen.
* Add qualification for links to field of structs (specifically callbacks);
* Escape #, @ and < as needed to avoid them being interpreted by Doxygen;
* Remove incorrect uses of "\see name", preferring #name;
* Fix a glitchy "\param Returns..." to be "\returns";
* Fix parameter names given to \param, typos and otherwise.

semantics of a ctor/dtor function-try-block catch handler
by pushing a normal cleanup is not just overkill but actually
actively wrong when the handler contains an explicit return
(which is only legal in a dtor).  Just emit the rethrow as
ordinary code at the fallthrough point.  Fixes PR13102.

modes. For languages other than C99/C11, this isn't quite a conforming
extension, and for C++11, it breaks some reasonable code containing
user-defined literals.

In languages which don't officially have hexfloats, pare back this extension
to only apply in cases where the token starts 0x and does not contain an
underscore. The extension is still not quite conforming, but it's a lot closer
now.

annotations in many places where it involved little change, fixed some
examples and marked code examples with \code...\endcode, and changed a few
nearby mentions of C++0x to refer to C++11.
