[PATCH] Several patches to improve libstdc++ API docs

[Jonathan Wakely <jwakely at redhat dot com>]

I've just committed a series of patches to improve the organization
and formatting of the Doxygen-generated API documentation.

- Update libstdc++ Doxygen config
- Adjust Doxygen processing of pb_ds containers
- Fix markup for Parallel Mode docs
- Improve Doxygen docs for nested namespaces
- Improve API docs for mathematical special functions
- Improve API docs for <memory> and <scoped_allocator>
- Improve docs for Filesystem TS
- Improve docs for Library Fundamentals TS
- Improve docs for Networking TS
- Improve docs for C++17 Filesystem library
- Improve docs for mutexes
- Allow Markdown formatting in Doxygen comments
- Miscellaneous API doc improvements

The patch is large so I've bzipped it, but it's almost entirely
changes to comments, with a couple of small re-arrangements of code to
improve the generated HTML docs.

Committed to trunk.

More changes coming soon too (including enabling Doxygen processing
for the C++17 components).
