The arguments passed to Copy() would normally be pointers, just like it
is done with other similar functions. This never worked correctly, as
the arguments were not validated correctly (not recognized) and the
error "Must specify either destination pool or destination image" always
got returned.
Modifying Image.Copy() into something usable would result in a complete
rewrite. Instead of a single Image.Copy() function that tries to cover
rbd_copy() and rbd_copy2(), provide Image.Copy() and Image.Copy2() so
that the API matches the librbd.so interface.

Now that cephfs_test.go is part of the cephfs package, the linter is
checking it and finding errors. Fix them.

Convert cephfs packages previously unexposed type to a public one and
replace a bunch of the existing boilerplate error handling with a
convenience function similar to those found ind rbd and rados.

The return value of rbd_discard() is the number of bytes that have been
discarded, or in case of an error, a negative errno value.
It seems Image.Discard() never can have worked as intended, unless the
error was disregarded. Just like Image.Write(), Image.Discard() should
return a tuple of the number of bytes discarded and an error.

rbd_get_features() returns a uint64_t with the features that are set in
the image. That means combining (with logical OR) features should result
in a uint64 too. Marking all features explicitly uint64 makes it easier
and cleaner to set/test features.

Keeping the _test.go code in the same package allows for the testing
of private functions. AFAWK it is more conventional as well.

We recently created errors in the rbd that match the golang convention
but left aliases for external code. Switch the test code to use the
newer more standard form instead of the "aliases."

A recent PR added new error values that were similar to the existing
naming convention but were not the normal go convention. Change all the
errors to match typical convention but leave the older names as aliases
such that older code will continue to work (for now).

By convention many projects are separating the golang stdlib imports
from other imports. Do that as well for rbd.go.

After discussion we decided to entirely drop logging from the library.
Future users should rely instead of the error types and values the

Revive is a tool similar to golint but can be configured. Add an initial
configuration for revive.
This configuration reduces the initial issue list to something more
manageable and that can be worked on incrementally rather than trying to
boil to ocean to make the checker happy.

Make it possible to easily validate the *Image and *Snapshot objects
before using them. This makes the use of go-ceph for RBD functions more
stable, and it is less likely that incorrect use causes Go panics.

Oddly, probably a historical artifact, the .go files in the root of the
go-ceph tree were named "rados". As rados is one of our sub-packages it
seemed more correct to call the package "ceph". This was chosen as
"go-ceph" is not a valid identifier in go and since this is already go
code prefixing with "go" seems a bit redundant.

The C library offers rbd_create2() and rbd_create3() and does not try to
cover all options with rbd_create(). For users that are familiar with
the C API, the Create2() and Create3() functions have been added.
The existing Create() API still handles the complete set of
rbd_create*() functions, so backwards compatibility is covered.

According to the 'go test' help, "The idiomatic way to disable test
caching explicitly is to use -count=1." This removes GOCACHE=off in

Adds cli parsing to the entrypoint script allowing for:
1. Custom path to micro-osd script
This allows easier testing of the script itself or quick
and dirty customization for special one-off tests
2. Selecting tests to run (or "ALL" or "NONE")
This allows the user to run only a subset of the tests as needed.
3. Option to pause indefinitely after tests complete
This keeps the containerized environment alive after tests
have run for debugging or just for creating a quick and dirty
ceph environment for playing around.
