currently, the iterator goes over *all* chunks of the index, even
those already backed up by a previous snapshots in the same tape
backup. this is bad since for each iterator, we stat each chunk to
sort by inode number. so to avoid stat'ing the same chunks over
and over for consecutive snapshots, add a 'skip_fn' to the iterator
and in the pool writer and check the catalog_set if we can skip it
this means we can drop the later check for the catalog_set
(since we don't modify that here)

Adds the '--force' flag to the proxmox-tape command allowing users
with root privileges to overwrite the passphrase of a given key.
Signed-off-by: Stefan Sterz <s.sterz@proxmox.com>
When force is used, the current passphrase is not required. Instead
it will be read from the file pointed to by TAPE_KEYS_FILENAME and
the old key configuration will be overwritten using the new
passphrase. Requires super user privileges.

the same navigation level, but if we switch to a completely different
component (e.g., fom `Options -> Others` to `Datastore foo`) we can

Avoids latency for restore-VMs that are finished fast but not ready
yet the first round while not checking to often for slower ones, iow,
we assume that the start up distribution is looking like a chi-square
Χ² with k=3.
With 25*round we get at max 45 rounds totalling to 25.875 s delay and
1.125 max between-round delay, which still provides an ok reaction
time.

glibc's malloc has a misguided heuristic to detect transient allocations that
will just result in allocation sizes below 32 MiB never using mmap.
That it turn means that those relatively big allocations are on the heap where
cleanup and returning memory to the OS is harder to do and easier to be blocked
by long living, small allocations at the top (end) of the heap.
Observing the malloc size distribution in a file-level backup run:

We see that all allocations will be on the heap, and that while most
allocations are small, the relatively few big ones will still make up most of
the RSS and if blocked from being released back to the OS result in much higher
peak and average usage for the program than actually required.
Avoiding the "dynamic" mmap-threshold increasement algorithm and fixing it at
the original default of 128 KiB reduces RSS size by factor 10-20 when running
backups. As with memory mappings other mappings or the heap can never block
freeing the memory fully back to the OS.
But, the drawback of using mmap is more wasted space for unaligned or small
allocation sizes, and the fact that the kernel allegedly zeros out the data
before giving it to user space. The former doesn't really matter for us when
using it only for allocations bigger than 128 KiB, and the latter is a
trade-off, using 10 to 20 times less memory brings its own performance
improvement possibilities for the whole system after all ;-)
