Ongoing documentation cleanup: fixed Doxygen markup errors, added \brief
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.

PR12717: Clang supports hexadecimal floating-point literals in all language
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.

It turns out that implementing the rethrow-on-fallthrough
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.

Documentation cleanup for clang-c:
* 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.
