Add an option, --stdin, to merge-tree which will accept lines of input
with two branches to merge per line, and which will perform all the
merges and give output for each in turn. This option implies -z, and
modifies the output to also include a merge status since the exit code
of the program can no longer convey that information now that multiple
merges are involved.
This could be useful, for example, by Git hosting providers. When one
branch is updated, one may want to check whether all code reviews
targetting that branch can still cleanly merge. Avoiding the overhead
of starting up a separate process for each of those code reviews might
provide significant savings in a repository with many code reviews.

When running `git merge-tree --write-tree`, we previously would only
return an exit status reflecting the cleanness of a merge, and print out
the toplevel tree of the resulting merge. Merges also have
informational messages, such as:
* "Auto-merging <PATH>"
* "CONFLICT (content): ..."
* "CONFLICT (file/directory)"
* etc.
In fact, when non-content conflicts occur (such as file/directory,
modify/delete, add/add with differing modes, rename/rename (1to2),
etc.), these informational messages may be the only notification the
user gets since these conflicts are not representable in the contents
of the file.
Add a --[no-]messages option so that callers can request these messages
be included at the end of the output. Include such messages by default
when there are conflicts, and omit them by default when the merge is
clean.

This adds the ability to perform real merges rather than just trivial
merges (meaning handling three way content merges, recursive ancestor
consolidation, renames, proper directory/file conflict handling, and so
forth). However, unlike `git merge`, the working tree and index are
left alone and no branch is updated.
The only output is:
- the toplevel resulting tree printed on stdout
- exit status of 0 (clean), 1 (conflicts present), anything else
(merge could not be performed; unknown if clean or conflicted)
This output is meant to be used by some higher level script, perhaps in
a sequence of steps like this:
NEWTREE=$(git merge-tree --write-tree $BRANCH1 $BRANCH2)
test $? -eq 0 || die "There were conflicts..."
NEWCOMMIT=$(git commit-tree $NEWTREE -p $BRANCH1 -p $BRANCH2)
git update-ref $BRANCH1 $NEWCOMMIT
Note that higher level scripts may also want to access the
conflict/warning messages normally output during a merge, or have quick
access to a list of files with conflicts. That is not available in this
preliminary implementation, but subsequent commits will add that
ability (meaning that NEWTREE would be a lot more than a tree in the
case of conflicts).
This also marks the traditional trivial merge of merge-tree as
deprecated. The trivial merge not only had limited applicability, the
output format was also difficult to work with (and its format
undocumented), and will generally be less performant than real merges.

Note that real merges differ from trivial merges in that they handle:
- three way content merges
- recursive ancestor consolidation
- renames
- proper directory/file conflict handling

As the previous commit shows, the presence of an oid in each level of
the traverse_info is confusing and ultimately not necessary. Let's drop
it to make it clear that it will not always be set (as well as convince
us that it's unused, and let the compiler catch any merges with other
branches that do add new uses).
Since the oid is part of name_entry, we'll actually stop embedding a
name_entry entirely, and instead just separately hold the pathname, its
length, and the mode.
This makes the resulting code slightly more verbose as we have to pass
those elements around individually. But it also makes it more clear what
each code path is going to use (and in most of the paths, we really only
care about the pathname itself).
A few of these conversions are noisier than they need to be, as they
also take the opportunity to rename "len" to "namelen" for clarity
(especially where we also have "pathlen" or "ce_len" alongside).

We assume that if setup_traverse_info() is passed a non-empty "base"
string, that string is pointing into a tree object and we can read the
object oid by skipping past the trailing NUL.
As it turns out, this is not true for either of the two calls, and we
may end up reading garbage bytes:
1. In git-merge-tree, our base string is either empty (in which case
we'd never run this code), or it comes from our traverse_path()
helper. The latter overallocates a buffer by the_hash_algo->rawsz
bytes, but then fills it with only make_traverse_path(), leaving
those extra bytes uninitialized (but part of a legitimate heap
buffer).
2. In unpack_trees(), we pass o->prefix, which is some arbitrary
string from the caller. In "git read-tree --prefix=foo", for
instance, it will point to the command-line parameter, and we'll
read 20 bytes past the end of the string.
Interestingly, tools like ASan do not detect (2) because the process
argv is part of a big pre-allocated buffer. So we're reading trash, but
it's trash that's probably part of the next argument, or the
environment.
You can convince it to fail by putting something like this at the
beginning of common-main.c's main() function:
{
int i;
for (i = 0; i < argc; i++)
argv[i] = xstrdup_or_null(argv[i]);
}
That puts the arguments into their own heap buffers, so running:
make SANITIZE=address test
will find problems when "read-tree --prefix" is used (e.g., in t3030).
Doubly interesting, even with the hackery above, this does not fail
prior to ea82b2a085 (tree-walk: store object_id in a separate member,
2019-01-15). That commit switched setup_traverse_info() to actually
copying the hash, rather than simply pointing to it. That pointer was
always pointing to garbage memory, but that commit started actually
dereferencing the bytes, which is what triggers ASan.
That also implies that nobody actually cares about reading these oid
bytes anyway (or at least no path covered by our tests). And manual
inspection of the code backs that up (I'll follow this patch with some
cleanups that show definitively this is the case, but they're quite
invasive, so it's worth doing this fix on its own).
So let's drop the bogus hashcpy(), along with the confusing oversizing
in merge-tree.

When parsing a tree, we read the object ID directly out of the tree
buffer. This is normally fine, but such an object ID cannot be used with
oidcpy, which copies GIT_MAX_RAWSZ bytes, because if we are using SHA-1,
there may not be that many bytes to copy.
Instead, store the object ID in a separate struct member. Since we can
no longer efficiently compute the path length, store that information as
well in struct name_entry. Ensure we only copy the object ID into the
new buffer if the path length is nonzero, as some callers will pass us
an empty path with no object ID following it, and we will not want to
read past the end of the buffer.

The interface into "xdiff" library used to discover the offset and

out. A new interface has been introduced to allow callers a more
direct access to them.

diff: discard hunk headers for patch-ids earlier
diff: avoid generating unused hunk header lines
xdiff-interface: provide a separate consume callback for hunks
xdiff: provide a separate emit callback for hunks
The xdiff library always emits hunk header lines to our callbacks as
formatted strings like "@@ -a,b +c,d @@\n". This is convenient if we're
going to output a diff, but less so if we actually need to compute using
those numbers, which requires re-parsing the line.
In preparation for moving away from this, let's teach xdiff a new
callback function which gets the broken-out hunk information. To help
callers that don't want to use this new callback, if it's NULL we'll
continue to format the hunk header into a string.
Note that this function renames the "outf" callback to "out_line", as
well. This isn't strictly necessary, but helps in two ways:
1. Now that there are two callbacks, it's nice to use more descriptive
names.
2. Many callers did not zero the emit_callback_data struct, and needed
to be modified to set ecb.out_hunk to NULL. By changing the name of
the existing struct member, that guarantees that any new callers
from in-flight topics will break the build and be examined
manually.

Using the more restrictive oideq() should, in the long run,
give the compiler more opportunities to optimize these
callsites. For now, this conversion should be a complete
noop with respect to the generated code.
The result is also perhaps a little more readable, as it
avoids the "zero is equal" idiom. Since it's so prevalent in
C, I think seasoned programmers tend not to even notice it
anymore, but it can sometimes make for awkward double
negations (e.g., we can drop a few !!oidcmp() instances
here).
This patch was generated almost entirely by the included
coccinelle patch. This mechanical conversion should be
completely safe, because we check explicitly for cases where
oidcmp() is compared to 0, which is what oideq() is doing
under the hood. Note that we don't have to catch "!oidcmp()"
separately; coccinelle's standard isomorphisms make sure the
two are treated equivalently.
I say "almost" because I did hand-edit the coccinelle output
to fix up a few style violations (it mostly keeps the
original formatting, but sometimes unwraps long lines).
