As serde_json will otherwise read files 1 byte at a time.
Writing is a bit better, but syntacitcal elements (quotes, braces,
commas) still often show up as single write syscalls, so use BufWriter
there as well.
Note that while we do store the file in the resulting objects, we do not
need to keep the buffered read/writers as we always `seek` to the
beginning on further file operations.

added a parameter to the cli for importing tape key via a json-parameter or
via reading a exported paperkey-file or json-file.
For this i also added a backupkey parameter to the api, but here it only
accepts json.
The cli interprets the parameter first as json-string, then json-file
and last as paperkey-file.
functionality:
proxmox-tape key paperkey [fingerprint of existing key] > paperkey.backup
proxmox-tape key restore --backupkey paperkey.backup # key from line above
proxmox-tape key restore --backupkey paperkey.json # only the json
proxmox-tape key restore --backupkey '{"kdf": {"Scrypt": ...' # json as string
for importing the key as paperkey-file it is irrelevant, if the paperkey got exported as html
or txt.

the latest changes to this api call changed/removed some things that
were actually necessary for the gui. Readd those and document them this
time.
The change from u64 to i64 limits us to 8EiB of Datastore sizes (instead if
16EiB) but if we reach that, we must adapt most other parts to use 128bit
sizes anyway

when we use http to make the api call, we have to parse the parameters
before, else we might send the string "true" instead of the boolean true
and the api rejects it with a 'Parameter verification error'.
We already have all api call schemas here, so parsing is possible.

this can only real fail for two reasons:
* the format is wrong:
this should not happen unless the format changed, then it will
happen every time
* the file can't be read:
this can happen if a user deletes and recreates a dataset manually,
since the mapped file does not exist anymore but the dataset does
for the second case, delete the mapping from the hashmap, so that the
next call will refresh the mapping with the correct file

currently, we sort chunks by inode when verifying or backing up to tape.
we get the inode# by stat'ing each chunk, which may be more expensive
than the gains of reading the chunks in order
Since that is highly dependent on the underlying storage of the datastore,
introduce a tuning option so that the admin can tune that behaviour
for each datastore.
The default stays the same (sorting by inode)

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.

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 ;-)
