In addition to the .pxarexclude files, glob match patterns can be passed to pxar
also via cli parameters.
Therefore the warning is rephrased to be more ambiguous.

- do not "double"-block_in_place() (it may not be nested)
- do not call block_in_place() in non-worker threads
is_in_tokio() isn't sufficient, we need to actually know
that we're in a worker-thread, so we do this by remembering
that we're blocking.

tokio now has Handle::try_current() allowing us to
generally check for a tokio runtime even if spawned by
someone else

We want to avoid pbs if possible and also avoid placing internal
binaries, not intended for human direct use, in /bin or /sbin paths.

Modeled after the one from PVE, but using rust instead of perl for
resolving the nodename and writing to /etc/issue
Behavior differs a bit. We write all non-loopback addresses to this
file, as the gui accepts connections from them all, so limiting it to
the first one is not really sensible.
Further an error to resolve, or only getting loopback addresses won't
write out an empty /etc/issue file, but a note about the error at the
place where the address would be displayed.
Named it "pbsbanner", not "proxmox-backup-banner" as it's rather an
internal tool anyway and mirrors pvebanner, pmgbanner

Two or more successive slashes should be allowed and treated as a single slash.
We also do not treat two successive slashes at the beginning of a path any
different.

Context::find_goodbye_entry() is removed and incorporated into the lookup
callback in order to take advantage of the entry_cache and since it is only used
inside this callback.
All entries read on lookup are cached.

By storing the payload start offset in the `DirectoryEntry` and passing this
information to `Decoder::read()`, the payload can be read directly and a repeated
re-reading of the entry information is avoided.

ACLs are stored separately in the pxar archive. This implements the functionality
needed to read the ACLs and return them as extended attributes in the getxattr

The goodbye table of directory entries is cached in a LRU cache to speed up
subsequent accesses.
This is especially important for directories with many entries, as then the
readdirplus callback is called repeatedly because of the limited reply buffer
size.
`DirectoryEntry`s are cached for subsequent access in their own LRU cache,
independent of the goodbye tables.
In order to avoid borrow conflicts, the `Context` provides a fn as_mut_refs
as well as a fn run_with_context_refs.
