b4d3859b9e #6407 - Document Borg 1.2 pattern behavior change
Make clear that absolute paths always go into the matcher as if they are relative (without leading slash). Adapt all examples accordingly.

6bfdb3f630 refactor hardlink_master processing globally
borg now has the chunks list in every item with content.
due to the symmetric way how borg now deals with hardlinks using
item.hlid, processing gets much simpler.

but some places where borg deals with other "sources" of hardlinks
still need to do some hardlink management:
borg uses the HardLinkManager there now (which is not much more
than a dict, but keeps documentation at one place and avoids some
code duplication we had before).

item.hlid is computed via hardlink_id function.

support hardlinked symlinks, fixes #2379
as we use item.hlid now to group hardlinks together,
there is no conflict with the item.source usage for
symlink targets any more.

2nd+ hardlinks now add to the files count as did the 1st one.
for borg, now all hardlinks are created equal.
so any hardlink item with chunks now adds to the "file" count.

ItemFormatter: support {hlid} instead of {source} for hardlinks

(docs) Recommend umask for passphrase file perms
The previous sample for creating a ~/.borg-passphrase file creates it first and then chmod's it to 400 permissions. That's probably fine in practice, but means there's a tiny window where the passphrase file is sitting with default permissions (likely world readable, depending on the system umask).

It seems safer to first change the umask to remove all group & world bits (0077) _before_ creating the file. To be polite and avoid messing with the user's previous umask, we do this in a subshell. (Note that umask 0077 leads to a mode of 600 rather than the previous 400, because removing the owner write bit doesn't seem to buy much since the owner can just chmod the file anyway.)

e8069a8f80 import/export-tar: --tar-format=BORG: roundtrip ALL item metadata, fixes #5830
export-tar: just msgpack and b64encode all item metadata and
            put that into a BORG specific PAX header.
            this is *additional* to the standard tar metadata.

import-tar: when detecting the BORG specific PAX header, just get
            all metadata from there (and ignore the standard tar
            metadata).

37f237d3e0 remove PassphraseKey code and borg key migrate-to-repokey command
"passphrase" encryption mode repos can not be created since borg 1.0.
back then, users were advised to switch existing repos of that type
to repokey mode using the "borg key migrate-to-repokey" command.
that command is still available in borg 1.0, 1.1 and 1.2, but not
any more in borg >= 1.3.

while we still might see the PassphraseKey.TYPE byte in old repos,
it is handled by the RepoKey code since borg 1.0.

All these are unsupported since long.

Newer versions of LibreSSL have gained chacha20-poly1305 support,
but still lack aes256-ocb support.
Also they have the HMAC_CTX_new/free api now.

docs: openssl >= 1.1.1 is required now
anything older is out of support anyway.

94e93ba7e6 formula is only approximately correct
the movement of the start of the hashing window stops at (file_size - window_size), thus THAT would be the factor in that formula, not just file_size.

for medium and big files, window_size is much smaller than file_size, so guess we can just say "approximately" for the general case.

37e1ae4735 Fix exceptions thrown by setup.py build_man
While doing some doc updates I needed a way to test them - to build
the documentation and inspect the output. I ran into an issue:
running python setup.py build_man was throwing exceptions:

1. The import-tar parser had a None description causing:

    File "/home/user/borg/setup_docs.py", line 451, in write_heading
      write(char * len(header))
    TypeError: object of type 'NoneType' has no len()

2. There was no docs/usage/import-tar.rst causing an exception too

b8bb0494f6 create --sparse, file map support for the "fixed" chunker, see #14
a file map can be:

- created internally inside chunkify by calling sparsemap, which uses
  SEEK_DATA / SEEK_HOLE to determine data and hole ranges inside a
  seekable sparse file.
  Usage: borg create --sparse --chunker-params=fixed,BLOCKSIZE ...
  BLOCKSIZE is the chunker blocksize here, not the filesystem blocksize!

- made by some other means and given to the chunkify function.
  this is not used yet, but in future this could be used to only read
  the changed parts and seek over the (known) unchanged parts of a file.

sparsemap: the generate range sizes are multiples of the fs block size.
           the tests assume 4kiB fs block size.
