Problem was that the malloc-replacing tools (memcheck, addrcheck, massif, helgrind) would assert if a too-big malloc was attempted. Now they return 0 to the client. I also cleaned up the code handling heap-block-metadata in Massif and Addrcheck/Memcheck a little. This exposed a nasty bug in VG_(client_alloc)() which wasn't checking if find_map_space() was succeeding before attempting an mmap(). Before I added the check, very big mallocs (eg 2GB) for Addrcheck were overwriting the client space at address 0 and causing crashes. Added a regtest to all the affected skins for this. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@2462
