metadata --batch --json: Reject input whose "fields" does not consist of
arrays of strings. Such invalid input used to be silently ignored.
Used to be that parseJSON for a JSONActionItem ran parseJSON separately
for the itemAdded, and if that failed, did not propagate the error. That
allowed different items with differently named fields to be parsed.
But it was actually only used to parse "fields" for metadata, so that
flexability is not needed.
The fix is just to parse "fields" as-is. AddJSONActionItemFields is needed
only because of the wonky way Command.MetaData adds onto the started json
object.
Note that this line got a dummy type signature added,
just because the type checker needs it to be some type.
itemFields = Nothing :: Maybe Bool
Since it's Nothing, it doesn't really matter what type it is,
and the value gets turned into json and is then thrown away.

Turns out that CommandStart actions do not have their exceptions caught,
which is why the giveup was causing a crash. Mostly these actions
do not do very much work on their own, but it does seem possible there
are other commands whose CommandStart also throws an exception.
So, my first attempt at a fix was to catch those exceptions. But,
--json-error-messages then causes a difficulty, because in order to output
a json error message, an action needs to have been started; that sets up
the json object that the error message will be included in a field of.
While it would be possible to output an object with just an error field,
this would be json output of a format that the user has no reason to
expect, that happens only in an exceptional circumstance. That is something
I have always wanted to avoid with the json output; while git-annex man
pages don't document what the json looks like, the output has always
been made to be self-describing. Eg, it includes "error-messages":[]
even when there's no errors.
With that ruled out, it doesn't seem a good idea to catch CommandStart
exceptions and display the error to stderr when --json-error-messages
is set. And so I don't know if it makes sense to catch exceptions from that
at all. Maybe I'd have a different opinion if --json-error-messages did not
exist though.
So instead, output a blank line like other batch commands do.
This also leaves open the possibility of implementing support for matching
object with metadata --json, which would also want to output a blank line
when the input didn't match.

addurl: Support adding the same url to multiple files at the same time when
using -J with --batch --with-files.
Implementation was easier than expected, was able to reuse OnlyActionOn.
While it will download the url's content multiple times, that seems like
the best thing to do; see my comment for why.

This makes it be displayed in the error-messages field with
--json-error-messages. And with --quiet, it will let it be displayed,
which makes sense because it's telling the user why what they requested
to do has failed to happen.
This opens the potential for the object file to be in place but
git-annex is interrupted before it can freeze it. git-annex fsck already
fixes that situation, which can also occur when lockContentForRemoval
thaws content.
Also improve comment to not be Windows-specific.
This change better supports Windows ACL management using
annex.freezecontent-command and annex.thawcontent-command and matches
the behaviour of adding an unlocked file.
By calling freezeContent after the file has moved into the annex,
the file's delete permission can be denied. If the file's delete
permission is denied before moving into the annex, the file cannot
be moved or deleted. If the file's delete permission is not denied after
moving into the annex, it will likely inherit a grant for the delete
permission which allows it to be deleted irrespective of the permissions
of the parent directory.
Caused by dirContains ".." "foo" being incorrectly False.
Also added a test of dirContains, which includes all the previous bug fixes
I could find and some obvious cases.

Fix bug that caused stale git-annex branch information to read when
annex.private or remote.name.annex-private is set.
The private journal file should not prevent reading more current
information from the git-annex branch, but used to.
Note that, overBranchFileContents has to do additional work now, when
there's a private journal file, it reads from the branch redundantly
and more slowly.
