Various libs ported to RTEMS

[Sebastien Bourdeauducq]

Hi,

I recently got several 'standard' libraries to work under RTEMS:
* libgd (image manipulation)
* libcurl (network client library for HTTP and many other protocols)
* expat (XML parser)
* libconfig (configuration file management)
* openjpeg (JPEG2000)
* jbig2dec (JBIG2, a B&W image format)
* mupdf (PDF rendering)

If you are interested in them, some build instructions are available at:

So far, the only major problem that I have noticed is that timeouts do
not work in libcurl (CURLOPT_CONNECTTIMEOUT and CURLOPT_TIMEOUT).
