I guess this question might have been discussed... is it possible to call
regular libc functions and rump APIs (such as rump_sys_XXXX) in the same C

If you are running in host namespace, yes. If you are running in full
rump kernel namespace, no. For examples of the former, see
buildrump.sh/tests. For examples of the latter, see rumprun.
For example, is there an easy way to implement a 'cp' command to copy
between Linux host FS and the rump FS ?
That's a very multifaceted question. You can use e.g. rumpctrl/dd to
move single files against live rump servers or the fsu_ecp command from
fs-utils against cold images. fs-utils doesn't not currently work
against live servers, but in theory it would not be a big task to adjust
it to work that way. (fs-utils is also a good example of how to call
both host syscalls and rump kernel syscalls in the same program)
