I got a "rados: ret=-22" message as part of call I made. I'm a bit rusty with my
C stderror codes, which made the error a bit unhelpful.
This commit makes this particular error come out as "rados: invalid argument",
even if we don't need to explicitly create a Rados error variable for invalid
argument case. It does so by using C.strerror().
A further change is that with this, we do not need to explicitly code
RadosErrorNotFound and RadosErrorPermissionsDenied using a different error type
thank RadosError.
The current IOContext struct has a ListObjects() method that works well for
pools with a reasonable number of objects. However, for very large pools, having
finer control over the iteration may be desirable.
This commit adds a new Iter() interface for pools. It allows callers to stop
iterating at any time by issuing a iter.Close(). It also allows callers to
"Seek" into the pool list using a token object.
In Go, the "C" package is a special type of package that creates local symbols
names (non exportable) to the importing package. The result, in the case of
rados.GetRadosError() is that trying to use results in:
cannot use cerr (type C.int) as type rados.C.int in argument to rados.GetRadosError
It seems that "C.int" within 'rados' namespace produces a symbol of the type
`_Ctype_int`, which given it's first character `_` is not exported. As such, we
have the type being defined as `rados._Ctype_int`, which is not accessible
outside of the rados package.
This commit changes the interface to use the native Go `int` type.
* `ListOmapValues` allows to iterate on all the key feteched during
a read operation of an omap (the goal is to easily get the last
read key from the C iterator. This one can then be used in another
call as `startAfter` parameter).
* `GetAllOmapValues` returns all the keys / values of the whole omap
* `GetOmapValues` now uses `ListOmapValues`

Added a function to List Xattrs, which returns a map of all xattrs set
on an object, errors out otherwise
