Fixed markdown formatting in porting README for doxygen output. The underscores and the newlines for the list were lost before.

Porting
=======
Fixed crash if initialization of EGL failed but was tried again later. The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly uninitialized data structure if loading the library first failed. A later try to use EGL then skipped initialization and assumed it was previously successful because the data structure now already existed. This led to at least one crash in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was dereferenced to make a call to eglBindAPI().

* Porting To A New Platform
The first thing you have to do when porting to a new platform, is look at
include/SDL_platform.h and create an entry there for your operating system.

The standard format is "__PLATFORM__", where PLATFORM is the name of the OS.

Ideally SDL_platform.h will be able to auto-detect the system it's building
on based on C preprocessor symbols.
There are two basic ways of building SDL at the moment:
1. The "UNIX" way: ./configure; make; make install
If you have a GNUish system, then you might try this. Edit configure.in,
take a look at the large section labelled:

Add a section for your platform, and then re-run autogen.sh and build!
2. Using an IDE:
If you're using an IDE or other non-configure build system, you'll probably
want to create a custom SDL_config.h for your platform. Edit SDL_config.h,
add a section for your platform, and create a custom SDL_config_{platform}.h,
Updated file name in porting README.

Once you have a working library without any drivers, you can go back to each
of the major subsystems and start implementing drivers for your platform.
If you have any questions, don't hesitate to ask on the SDL mailing list:

Enjoy!
