iovec-wrapper: rename iovw_append() to iovw_extend()
...
The naming is consistent with strv_extend().
This also
- introduces tiny iovw_extend_iov() wrapper,
- refuse when the source and target points to the same object,
- check the final count before extending in iovw_extend_iovw().

iovec-wrapper: introduce iovw_concat()
...
This is similar to iovw_to_cstring(), but allows embedded NUL, as this
just concat multiple iovec, the result may not be a string.
Now, iovw_to_cstring() internally uses iovw_concat().

iovec-wrapper: fix memleak in iovw_consume() when len == 0
...
This makes even when len == 0, the input buffer is freed.
The behavior is consistent with strv_consume() and friends.
