malloc functions, which automatically cast to the same type they're allocating the size of. Should prevent any future errors involving mallocing the size of the wrong structure type, and will also make life easier if we ever need to turn the PuTTY core code from real C into C++-friendly C. I haven't touched the Mac frontend in this checkin because I couldn't compile or test it. [originally from svn r3014]
