[evolution-patches] 313284, valgrind issues in camel stuff

[Not Zed <notzed ximian com>]

I dont know how important these are, but they fix some minor bugs in the
code.  Some could lead to buffer overruns (reading only), which may end
up with invalid data elsewhere down the track.

It removes a bunch of warnings that users dont need to see too, like
charset things.

+
+	* camel-mime-parser.c (folder_scan_content): make sure *data is
+	set to something before we exit.
+
+	* camel-mime-parser.c (folder_read): use memmove, not memcpy,
+	since memory areas could overlap.
+
+	* camel-html-parser.c (tokenise_step): use the length from the
+	utf8 conversion, it isn't 0 terminated.
+
+	* camel-mime-utils.c (header_decode_quoted_string): if we run out
+	of string, then don't go past the 0.

 	* camel-store.c (camel_store_get_folder): add some debug logging.
