14ba97f81c alloc: allow arbitrary repositories for alloc functions
We have to convert all of the alloc functions at once, because alloc_report
uses a funky macro for reporting. It is better for the sake of mechanical
conversion to convert multiple functions at once rather than changing the
structure of the reporting function.

We record all memory allocation in alloc.c, and free them in
clear_alloc_state, which is called for all repositories except
the_repository.

18cfc08866 submodule.c: move submodule merging to merge-recursive.c
In a later patch we want to improve submodule merging by using the output()
function in merge-recursive.c for submodule merges to deliver a consistent
UI to users.

To do so we could either make the output() function globally available
so we can use it in submodule.c#merge_submodule(), or we could integrate
the submodule merging into the merging code. Choose the later as we
generally want to move submodules closer into the core.

Therefore we move any function related to merging submodules
(merge_submodule(), find_first_merges() and print_commit) to
merge-recursive.c.  We'll keep add_submodule_odb() in submodule.c as it
is used by other submodule functions. While at it, add a TODO note that
we do not really like the function add_submodule_odb().

This commit is best viewed with --color-moved.

e30d833671 git-submodule.sh: try harder to fetch a submodule
This is the logical continuum of fb43e31f2b (submodule: try harder to
fetch needed sha1 by direct fetching sha1, 2016-02-23) and fixes it as
some assumptions were not correct.

The commit states:
> If $sha1 was not part of the default fetch ... fail ourselves here
> assumes that the fetch_in_submodule only fails when the serverside does
> not support fetching by sha1.

There are other failures, why such a fetch may fail, such as
    fatal: Couldn't find remote ref HEAD
which can happen if the remote side doesn't advertise HEAD and we do not
have a local fetch refspec.

Not advertising HEAD is allowed by the protocol spec and would happen,
if HEAD points at an unborn branch for example.

Not having a local fetch refspec can happen when submodules are fetched
shallowly, as then git-clone doesn't setup a fetch refspec.

So do try even harder for a submodule by ignoring the exit code of the
first fetch and rather relying on the following is_tip_reachable to
see if we try fetching again.

4362da078e t7005-editor: get rid of the SPACES_IN_FILENAMES prereq
The last two tests 'editor with a space' and 'core.editor with a

ensure that they are only run on filesystems that allow, well, spaces
in filenames.  However, we have been putting a space in the name of
the trash directory for just over a decade now, so we wouldn't be able
to run any of our tests on such a filesystem in the first place.

This prereq is therefore unnecessary, remove it.

d16ab63429 t/test-lib: add an SHA1 prerequisite
There are some basic tests in our codebase that test that we get fixed
SHA-1 values.  These are valuable because they make sure that our SHA-1
implementation is free of bugs, but obviously these tests will fail with
a different hash.

There are also tests which intentionally produce objects that have
collisions when truncated to a certain length to test our handling of
these cases.  These tests, too, will fail with a different hash.

Add an SHA1 prerequisite to annotate both of these types of tests and
disable them when we're using a different hash.  In the future, we will
create versions of these tests which handle both SHA-1 and NewHash.

8702b30fd7 mark_parents_uninteresting(): avoid most allocation
Commit 941ba8db57 (Eliminate recursion in setting/clearing
marks in commit list, 2012-01-14) used a clever double-loop
to avoid allocations for single-parent chains of history.
However, it did so only when following parents of parents
(which was an uncommon case), and _always_ incurred at least
one allocation to populate the list of pending parents in
the first place.

We can turn this into zero-allocation in the common case by
iterating directly over the initial parent list, and then
following up on any pending items we might have discovered.

43fc643b75 mark_parents_uninteresting(): replace list with stack
The mark_parents_uninteresting() function uses two loops:
an outer one to process our queue of pending parents, and an
inner one to process first-parent chains. This is a clever
optimization from 941ba8db57 (Eliminate recursion in
setting/clearing marks in commit list, 2012-01-14) to limit
the number of linked-list allocations when following
single-parent chains.

Unfortunately, this makes the result a little hard to read.
Let's replace the list with a stack. Then we don't have to
worry about doing this double-loop optimization, as we'll
just reuse the top element of the stack as we pop/push.

577dd0d29b mark_parents_uninteresting(): drop missing object check
We allow UNINTERESTING objects in a traversal to be
unavailable. As part of this, mark_parents_uninteresting()
checks whether we have a particular uninteresting parent; if
not, we will mark it as "parsed" so that later code skips
it.

This code is redundant and even a little bit harmful, so
let's drop it.

It's redundant because when our parse_object() call in
add_parents_to_list() fails, we already quietly skip
UNINTERESTING parents. This redundancy is a historical
artifact. The mark_parents_uninteresting() protection is
from 454fbbcde3 (git-rev-list: allow missing objects when
the parent is marked UNINTERESTING, 2005-07-10). Much later,
aeeae1b771 (revision traversal: allow UNINTERESTING objects
to be missing, 2009-01-27) covered more cases by making the
actual parse more gentle.

  As an aside, even if this weren't redundant, it would be
  insufficient. The gentle parsing handles both missing and
  corrupted objects, whereas the has_object_file() check
  we're getting rid of covers only missing ones.

And the code we're dropping is harmful for two reasons:

  1. We spend extra time on the object lookup, even though
     we don't actually need the information at this point
     (and will just repeat that lookup later when we parse
     for the common case that we _do_ have the object).

  2. It "lies" about the commit by setting the parsed flag,
     even though we didn't load any useful data into the
     struct. This shouldn't matter for the UNINTERESTING
     case, but we may later clear our flags and do another
     traversal in the same process. While pretty unlikely,
     it's possible that we could then look at the same
     commit without the UNINTERESTING flag, in which case
     we'd produce the wrong result (we'd think it's a commit
     with no parents, when in fact we should probably die
     due to the missing object).

a5411df0d9 mark_tree_contents_uninteresting(): drop missing object check
It's generally acceptable for UNINTERESTING objects in a
traversal to be unavailable (e.g., see aeeae1b771). When
marking trees UNINTERESTING, we access the object database
twice: once to check if the object is missing (and return
quietly if it is), and then again to actually parse it.

We can instead just try to parse; if that fails, we can then
return quietly. That halves the effort we spend on locating
the object.

Note that this isn't _exactly_ the same as the original
behavior, as the parse failure could be due to other
problems than a missing object: it could be corrupted, in
which case the original code would have died. But the new
behavior is arguably better, as it covers the object being
unavailable for any reason. We'll also still issue a warning
to stderr in such a case.
