[pbs-devel] [PATCH v5 proxmox proxmox-backup 0/6] fix 4788: statically linked proxmox-backup-client

[Christian Ebner <c.ebner@proxmox.com>]

As discussed in issue #4788 [0], statically linking of the
`proxmox-backup-client` still suffers from possible incompatible
dependencies on the NSS module libraries, further described in
[1].

This patch series provides the means to statically compile the client
with a workaround for the NSS lib limitation by relying on
`hickory-dns` [2], as suggested by Thomas.
The hickory-resolver is used for name resolution with the statically
compiled binary instead of the default `getaddrinfo` based
`GaiResolver`.

Since hickory-resolver depends on `ipconfig` for Windows targets when
the `system-config` feature is enabled (required to read nameservers
from `/etc/resolv.conf`), also the dependency on `ipconfig` is
required by cargo. To workaround this, a dummy crate is registered in
the cargo registry.

Changes since version 4:
- Incorporated additions and suggestions regarding debian packaging

Changes since version 3:
- Added default type GaiResolver to HttpsConnector
- Include patch to mention different name resolution behavior in docs

Changes since version 2:
- Use packaged version for hickory-resolver
- Drop unneeded `ipconfig` dependency workaround
- Rebased onto current master
