CogVM binaries as per VMMaker.oscog-eem.139/r2518.

Add access to VM arguments to Mac.  Make Windows, Mac and Unix consistent:

        Smalltalk getSystemAttribute:

                -1 => executable name

                -2 .. -n => VM arguments *including* image (if explicitly supplied).

Replace win32 command line parsing with unixesque code using CommandLineToArgvW.

linux launch script:

Cope with old linuxes use of /lib/tls hack for an optional thread-local-storage

version of libc/libpthread. The launch scripts add /lib/tls:/usr/lib/tls: to

LD_LIBRARY_PATH instead of /lib:/usr/lib: if the VM is linked to /lib/tls/libc.
