Revert "copiousoutput: cleanup after copiousoutput handling. Temporary files should"

I am reverting all copiousoutput support because of bug 917.
This reverts commit 4dc4ea47f2.

Conflicts:

	src/network/connection.h: After the original commit, the declaration
	  of copiousoutput_data had been changed to use the LIST_OF macro.
	  Also, connection.cgi had been added next to the connection.popen
	  member added by the original commit.
	src/session/download.c: After the original commit, the definition of
	  copiousoutput_data had been changed to use the INIT_LIST_OF macro.
