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().
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().
All non-test users iovec_wrapper define the struct as a field in a
bigger structure, so we never free it individually. Let's simplify the
code and assume it is never null.
Let's not leak details from src/shared and src/libsystemd into
src/basic, even though you can't actually do anything useful with
just forward declarations from src/shared.
The sd-forward.h header is put in src/libsystemd/sd-common as we
don't have a directory for shared internal headers for libsystemd
yet.
Let's also rename forward.h to basic-forward.h to keep things
self-explanatory.
instead of passing a boolean picking the destruction method just have
different functions. That's much nicer in context of _cleanup_, and how
we usually do things.
