Harden the fetch functions on iOS and unix to check for out-of-memory. The plugin now seems to work on unix but much work needs to be done to platforms/unix/vm-display-x11/sqUnixX11.c because playing with e.g. firefox shows that copying HTML text has no effect on the results passed up from clipboardGetTypeNames et al.
