This is less erorr-prone, and easier for the user to reason about; it
preserves the man page's promise that only explicitly included
information will be copied.
ghc 8.8.4 seems to have changed something that broke code that has been
successfully using forkProcess since 2012. Likely a change to GC internals.
Since forkProcess has never had clear documentation about how to
use it safely, avoid using it at all. Instead, when git-annex needs to
daemonize itself, re-run the git-annex command, in a new process group
and session.

Sometimes users would get confused because an option they were looking
for was not mentioned on a subcommand's man page, and they had not
noticed that the main git-annex man page had a list of common options.
This change lets each subcommand mention the common options, similarly
to how the matching options are handled.

smudge: Fix a case where an unlocked annexed file that annex.largefiles
does not match could get its unchanged content checked into git, due to git
running the smudge filter unecessarily.
When the file has the same inodecache as an already annexed file,
we can assume that the user is not intending to change how it's stored in
git.
Note that checkunchangedgitfile already handled the inverse case, where the
file was added to git previously. That goes further and actually sha1
hashes the new file and checks if it's the same hash in the index.
It would be possible to generate a key for the file and see if it's the
same as the old key, however that could be considerably more expensive than
sha1 of a small file is, and it is not necessary for the case I have, at
least, where the file is not modified or touched, and so its inode will
match the cache.
fromkey: Create an unlocked file when used in an adjusted branch where the
file should be unlocked, or when configured by annex.addunlocked.
There is some overlap with code in Annex.Ingest, however it's not quite the
same because ingesting has a temp file with the content, where here the
content, if any, is in the annex object file. So it eg, makes sense for
Annex.Ingest to copy the execute mode of the content file, but it does not make
sense for fromkey to do that.
Also changed in passing to stage the file in git directly, rather than
using git add. One consequence of that is that if the file is gitignored,
it will still get added, rather than the old behavior:
The following paths are ignored by one of your .gitignore files:
ignored
hint: Use -f if you really want to add them.
hint: Turn this message off by running
hint: "git config advice.addIgnoredFile false"
git-annex: user error (xargs ["-0","git","--git-dir=.git","--work-tree=.","--literal-pathspecs","add","--"] exited 123)
That old behavior was a surprise to me, and so I consider it a bug, and doubt
anyone would have relied on it.
Note that, when on an --hide-missing branch, it is possible to fromkey a key
that is not present (needs --force). The annex link or pointer file still gets
written in this case. It doesn't seem to make any sense not to write it,
because then fromkey would not do anything useful in this case, and this way
the file can be committed and synced to master, and the branch re-adjusted to
hide the new missing file.

Which could happen occasionally before when concurrency is enabled.
While not much of a problem when it did happen, better to avoid it. Also,
since it seems likely the gpg-agent sometimes fails in such a situation,
this makes it not happen when running a single git-annex command with
concurrency enabled.

I had been assuming that numcopies would be a larger or at most equal to
mincopies, so no need to check both. But users get confused and use configs
that don't really make sense, so make sure to handle mincopies being larger
than numcopies.
Also add something to the mincopies man page to discourage this
misconfiguration.

Which has otherwise been supported since 2019, but was missing from the
list of allowed repo-global configs.
Reordered the list to match the order in the git-annex-config man page, to
make them easy to cross-compare.
