When invoking podman/docker/etc. it is no longer needed to add fuse
support, or (AFAICT) keeping cap SYS_ADMIN.

Now that none of the tests need an external (fuse) mount of the fs under
test we can eliminate fuse from our ceph setup script.
Signed-off-by: John Mulligan <jmulligan@redhat.com>
Now that there are no tests using the fuse mount point and the useMount
function that detects an external mount point is needed, we can remove
the useMount function itself and the env var used to control it.

The external mount point was mainly used for stat prior to a Stat
function being part of go-ceph's cephfs package. Now that we have
Statx, we can replace the need for the external mount and os.Stat.

This adds a test that assures that the special //go:uintptrescapes comment
before the storeUntilRelease() function works as intended, that is the
garbage collector doesn't touch the object referenced by the uintptr until
the function returns after Release() is called. The test will fail if the
//go:uintptrescapes comment is disabled (removed) or stops working in future
versions of go.

In order to run CI jobs also on PRs that are based on other PRs, this
change adds the pattern 'pr/**' to the tested base branches. That
means, if PRs are pushed that are based on branches that start with
pr/... these PRs are also get tested. So, if we - by convention - push
PRs to branches like for example pr/ansiwen/myfix42, then all PRs
that are not based on master but another PR get tested as well.

The main motivation for PtrGuard was read and write buffers as they
are used in iovec. This change uses SyncBuffer for the iovec
implementation, so that the no-copy PtrGuard implementation can be
enabled with the with_ptrguard build tag.
Signed-off-by: Sven Anderson <sven@redhat.com>
In order to be able to swich on and off PtrGuard usage, SyncBuffer
implements a typical usage pattern of PtrGuard, that is a data buffer
referenced from inside a C allocated struct, in two ways: 1) using a
PtrGuard to dierctly store a pointer to the Go buffer in C memory, or
2) allocating a C buffer of same size and syncing data back with
C.memcpy(). The implementation can be chosen with the with_ptrguard
build tag.

As per go-ceph issue #427, and a discussion in #399 this change and
test ensure that the cephIoctx helper function, that extracts the
C.rados_ioctx_t from a Go rados.IOContext, never returns a nil/null
C type.
As these are always "programming errors" panicking is reasonable
behavior for this case.

The json key sent to retain snapshots on subvolume remove was misspelled
and had a dash in it rather than an underscore. Fix the incorrect key
and add a test, that needs to be able to run on version of cephfs w/o
snapshot retention, and verifies that flag does the correct thing.

Using WriteSame() to implement a zerofill function is less straight
forward than expected. `rbd_discard_on_zeroed_write_same` is a Ceph
option than affects the behaviour of WriteSame(). By default the option
is enabled, causing WriteSame() to call discard instead of writing
zeros.

Add functions:
* SetMirrorMode implementing rbd_mirror_mode_set
* GetMirrorMode implementing rbd_mirror_mode_get
* MirrorEnable implementing rbd_mirror_image_enable2
* MirrorDisable implementing rbd_mirror_image_disable
* MirrorPromote implementing rbd_mirror_image_promote
* MirrorDemote implementing rbd_mirror_image_demote
* MirrorResync implementing rbd_mirror_image_resync
* MirrorInstanceId implementing rbd_mirror_image_get_instance_id
For now, these mirroring related functions are only supported on octopus
builds. Right now the demand is for snapshot based mirroring, which is
new in octopus. We can always relax this in the future and add the
necessary support for nautilus, for journaling only based mirroring.

This change adds a new pointer alias CPtr, that should always only
contains pointers to C allocated memory and should always used for
such pointers in order to keep them separate from Go pointers more
easily. This is helpful, since only CPtr are allowed to be stored in
C allocated memory, and Go pointers can only be passed to C functions
if they don't point to memory not containing Go pointers again, that
is all pointers in such memory must be CPtr.
The change also adds aliases for C.malloc and C.free that return and
accept the CPtr type as a little safety measure.
Additionally there are some useful constants defined.
