No MapScript mechanism to process POST requests when not using cgi

[warmerdam]

Currently in non-cgi mapscript environments (such as when using php or python as a loaded module in Apache), it is not possible to process post requests because there is no mechanism to push the posted xml document into the msio subsystem.

To implement this, we would need to actually implement the msIO_bufferRead() function in mapio.c, and add a function to push data into this buffer (something roughly like msIO_getStdoutBufferString() and msIO_getStdoutBufferBytes() from mapscript/swiginc/msio.i but in the opposite direction).

While I understand what needs to be done, I'm not prepared to spend the time doing it since the need seems somewhat limited.

NOTE: This issue only affects someone wanting to use POST requests to WxS services from mapscript in a non-cgi environment (like mod_php or mod_python).

Frank: feel free to ping me for testing/etc.

Ditto. If you want to work on implementing this I'm available for debugging and testing.
