[pbs-devel] [PATCH v4 proxmox-backup 00/11] fix: #3847 pipe from STDIN to proxmox-backup-client

[Robert Obkircher <r.obkircher@proxmox.com>]

Add support for commands like:
    ssh host cmd | proxmox-backup-client backup data.img:/dev/stdin
    proxmox-backup-client backup a.img:<(mysqldump) b.img:<(pgdump)

Changes since v3:

From feedback:
- remove "fix" prefix from commits and ensure they all build
- preserve optional size in BackupEnvironment instead of updating it
- combine public methods of writer and remove Arc<ChunkStore>
- tests: use tmpdir, better names, additional asserts

New:
- use u64 instead of usize for content size
- centralize size computation and improve overflow checks
- mmap entire file to support larger page sizes
  - I'm working on separate patches to fix the Readers 
    (for #7244 - Support 16k page size)
