Extract dir creation code snippet from copy_or_link_directory to its own
function named mkdir_if_missing. This change will help to remove
copy_or_link_directory's explicit recursion, which will be done in a
following patch. Also makes the code more readable.

Make the copy_or_link_directory function no longer skip hidden
directories. This function, used to copy .git/objects, currently skips
all hidden directories but not hidden files, which is an odd behaviour.
The reason for that could be unintentional: probably the intention was
to skip '.' and '..' only but it ended up accidentally skipping all
directories starting with '.'. Besides being more natural, the new
behaviour is more permissive to the user.
Also adjust tests to reflect this behaviour change.

Add the possibility of giving flags to dir_iterator_begin to initialize
a dir-iterator with special options.
Currently possible flags are:
- DIR_ITERATOR_PEDANTIC, which makes dir_iterator_advance abort
immediately in the case of an error, instead of keep looking for the
next valid entry;
- DIR_ITERATOR_FOLLOW_SYMLINKS, which makes the iterator follow
symlinks and include linked directories' contents in the iteration.
These new flags will be used in a subsequent patch.
Also add tests for the flags' usage and adjust refs/files-backend.c to
the new dir_iterator_begin signature.

dir_iterator_advance() is a large function with two nested loops. Let's
improve its readability factoring out three functions and simplifying
its mechanics. The refactored model will no longer depend on
level.initialized and level.dir_state to keep track of the iteration
state and will perform on a single loop.
Also, dir_iterator_begin() currently does not check if the given string
represents a valid directory path. Since the refactored model will have
to stat() the given path at initialization, let's also check for this
kind of error and make dir_iterator_begin() return NULL, on failures,
with errno appropriately set. And add tests for this new behavior.
Improve documentation at dir-iteration.h and code comments at
dir-iterator.c to reflect the changes and eliminate possible
ambiguities.
Finally, adjust refs/files-backend.c to check for now possible
dir_iterator_begin() failures.

Change warning(..., strerror(errno)) by warning_errno(...). This helps
to unify warning display besides simplifying a bit the code. Also,
improve warning messages by surrounding paths with quotation marks and
using more meaningful statements.

There is currently an odd behaviour when locally cloning a repository
with symlinks at .git/objects: using --no-hardlinks all symlinks are
dereferenced but without it, Git will try to hardlink the files with the
link() function, which has an OS-specific behaviour on symlinks. On OSX
and NetBSD, it creates a hardlink to the file pointed by the symlink
whilst on GNU/Linux, it creates a hardlink to the symlink itself.
On Manjaro GNU/Linux:
$ touch a
$ ln -s a b
$ link b c
$ ls -li a b c
155 [...] a
156 [...] b -> a
156 [...] c -> a
But on NetBSD:
$ ls -li a b c
2609160 [...] a
2609164 [...] b -> a
2609160 [...] c
It's not good to have the result of a local clone to be OS-dependent and
besides that, the current behaviour on GNU/Linux may result in broken
symlinks. So let's standardize this by making the hardlinks always point
to dereferenced paths, instead of the symlinks themselves. Also, add
tests for symlinked files at .git/objects/.
Note: Git won't create symlinks at .git/objects itself, but it's better
to handle this case and be friendly with users who manually create them.

Add tests for what happens when we perform a local clone on a repo
containing odd files at .git/object directory, such as symlinks to other
dirs, or unknown files.
I'm bending over backwards here to avoid a SHA-1 dependency. See [1]
for an earlier and simpler version that hardcoded SHA-1s.
This behavior has been the same for a *long* time, but hasn't been
tested for.
There's a good post-hoc argument to be made for copying over unknown
things, e.g. I'd like a git version that doesn't know about the
commit-graph to copy it under "clone --local" so a newer git version
can make use of it.
In follow-up commits we'll look at changing some of this behavior, but
for now, let's just assert it as-is so we'll notice what we'll change
later.

In commit 8daec1df03 ("merge-recursive: switch from (oid,mode) pairs
to a diff_filespec", 2019-04-05), we actually switched from
(oid,mode,path) triplets to a diff_filespec -- but most callsites in the
patch only needed to worry about oid and mode so the commit message
focused on that. The oversight in the commit message apparently spilled
over to the code as well; one of the dozen or so callsites accidentally
dropped the setting of the path in the conversion. Restore the path
setting in that location.
Also, this pointed out that our testsuite was lacking a good rename/add
test, at least one that involved the need for merge content with the
rename. Add such a test, and since rename/add vs. add/rename could
possibly be important, redo the merge the opposite direction to make
sure we don't have issues with the direction of the merge. These
testcases failed before restoring the setting of path, but with the
paths appropriately set the testcases both pass.
