Change Details

Construct a struct image_args with the help of new exec_args_*() helper functions and call kern_execve(). The previous code mapped a page in userspace, copied arguments out to it one at a time, and then constructed a struct execve_args all so that sys_execve() can call exec_copyin_args() to copy the data back in to a struct image_args. Unlike sys_execve() we don't call pre_execve()/post_execve() as we don't need to worry about killing other threads in an old process.

Opencode the part of pre_execve()/post_execve() that releases a reference to the initial vmspace. We don't need to stop threads like they do.
