Attached is a new version of the patch that implements strace-like
functionallity for linux-user. Unlike the previous patch, this one
can be considered "complete" and ready for inclusion, and has already
proven to be useful for debugging problems.

Improvement over the previous patch include:

 	Activated by setting QEMU_STRACE env variable
 	cleaner integration into do_syscall()
 	Per syscall override of the output function to allow for
 		a more customized display of the parameters.
 	Per syscall override of the return value output function.
 	custom format string for a few more syscalls
