merge_trees() did a variety of work, including:
* Calling get_unmerged() to get unmerged entries
* Calling record_df_conflict_files() with all unmerged entries to
do some work to ensure we could handle D/F conflicts correctly
* Calling get_renames() to check for renames.
An easily overlooked issue is that get_renames() can create more
unmerged entries and add them to the list, which have the possibility of
being involved in D/F conflicts. So the call to
record_df_conflict_files() should really be moved after all the rename
detection. I didn't come up with any testcases demonstrating any bugs
with the old ordering, but I suspect there were some for both normal
renames and for directory renames. Fix the ordering.

t3501 had a testcase originally added in 05f2dfb965 (cherry-pick:
demonstrate a segmentation fault, 2016-11-26) to ensure cherry-pick
wouldn't segfault when working with a dirty file involved in a rename.
While the segfault was fixed, there was another problem this test
demonstrated: namely, that git would overwrite a dirty file involved in a
rename. Further, the test encoded a "successful merge" and overwriting of
this file as correct behavior. Modify the test so that it would still
catch the segfault, but to require the correct behavior. Mark it as
test_expect_failure for now too, since this second bug is not yet fixed.

There are various git subcommands (among them, clone) which don't set up
the repository (that is, they lack RUN_SETUP or RUN_SETUP_GENTLY) but
end up needing to have information about the hash algorithm in use.
Because the hash algorithm is part of struct repository and it's only
initialized in repository setup, we can end up dereferencing a NULL
pointer in some cases if we call one of these subcommands and look up
the empty blob or empty tree values.
A "git clone" of a project that has two paths that differ only in
case suffers from this if it is run on a case insensitive platform.
When the command attempts to check out one of these two paths after
checking out the other one, the checkout codepath needs to see if
the version that is already on the filesystem (which should not
happen if the FS were case sensitive) is dirty, and it needs to
exercise the hashing code at that point.
In the future, we can add a command line option for this or read it
from the configuration, but until we're ready to expose that
functionality to the user, simply initialize the repository
structure to use the current hash algorithm, SHA-1.

We normally print full command line, including the program and its
argument. When git_cmd is set, we have a special code path to run the
right "git" program and child_process.argv[0] will not contain the
program name anymore. As a result, we print just the command
arguments.
I thought it was a regression when the code was refactored and git_cmd
added, but apparently it's not. git_cmd mode was introduced before
tracing was added in 8852f5d704 (run_command(): respect GIT_TRACE -
2008-07-07) so it's more like an oversight in 8852f5d704.
Fix it, print the program name "git" in git_cmd mode. It's nice to have
now. But it will be more important later when we start to print env

Split index mode only has a few dedicated tests, but as the index is
involved in nearly every git operation, this doesn't quite cover all the
ways repositories with split index can break. To use split index mode
throughout the test suite a GIT_TEST_SPLIT_INDEX environment variable
can be set, which makes git split the index at random and thus
excercises the functionality much more thoroughly.
As this is not turned on by default, it is not executed nearly as often
as the test suite is run, so occationally breakages slip through. Try
to counteract that by running the test suite with GIT_TEST_SPLIT_INDEX
mode turned on on travis.
To avoid using too many cycles on travis only run split index mode in
the linux-gcc target only. The Linux build was chosen over the Mac OS
builds because it tends to be much faster to complete.
The linux gcc build was chosen over the linux clang build because the
linux clang build is the fastest build, so it can serve as an early
indicator if something is broken and we want to avoid spending the extra
cycles of running the test suite twice for that.

In a96d3cc3f6 ("cache-tree: reject entries with null sha1", 2017-04-21)
we made sure that broken cache entries do not get propagated to new
trees. Part of that was making sure not to re-use an existing cache
tree that includes a null oid.
It did so by dropping the cache tree in 'do_write_index()' if one of
the entries contains a null oid. In split index mode however, there
are two invocations to 'do_write_index()', one for the shared index
and one for the split index. The cache tree is only written once, to
the split index.
As we only loop through the elements that are effectively being
written by the current invocation, that may not include the entry with
a null oid in the split index (when it is already written to the
shared index), where we write the cache tree. Therefore in split
index mode we may still end up writing the cache tree, even though
there is an entry with a null oid in the index.
Fix this by checking for null oids in prepare_to_write_split_index,
where we loop the entries of the shared index as well as the entries for
the split index.
This fixes t7009 with GIT_TEST_SPLIT_INDEX. Also add a new test that's
more specifically showing the problem.

read_index_from() takes a path argument for the location of the index
file. For reading the shared index in split index mode however it just
ignores that path argument, and reads it from the gitdir of the current
repository.
This works as long as an index in the_repository is read. Once that
changes, such as when we read the index of a submodule, or of a
different working tree than the current one, the gitdir of
the_repository will no longer contain the appropriate shared index,
and git will fail to read it.
For example t3007-ls-files-recurse-submodules.sh was broken with
GIT_TEST_SPLIT_INDEX set in 188dce131f ("ls-files: use repository
object", 2017-06-22), and t7814-grep-recurse-submodules.sh was also
broken in a similar manner, probably by introducing struct repository
there, although I didn't track down the exact commit for that.
be489d02d2 ("revision.c: --indexed-objects add objects from all
worktrees", 2017-08-23) breaks with split index mode in a similar
manner, not erroring out when it can't read the index, but instead
carrying on with pruning, without taking the index of the worktree into
account.
Fix this by passing an additional gitdir parameter to read_index_from,
to indicate where it should look for and read the shared index from.
read_cache_from() defaults to using the gitdir of the_repository. As it
is mostly a convenience macro, having to pass get_git_dir() for every
call seems overkill, and if necessary users can have more control by
using read_index_from().

When calling convert_to_git(), the checksafe parameter defined what
should happen if the EOL conversion (CRLF --> LF --> CRLF) does not
roundtrip cleanly. In addition, it also defined if line endings should
be renormalized (CRLF --> LF) or kept as they are.
checksafe was an safe_crlf enum with these values:
SAFE_CRLF_FALSE: do nothing in case of EOL roundtrip errors
SAFE_CRLF_FAIL: die in case of EOL roundtrip errors
SAFE_CRLF_WARN: print a warning in case of EOL roundtrip errors
SAFE_CRLF_RENORMALIZE: change CRLF to LF
SAFE_CRLF_KEEP_CRLF: keep all line endings as they are
In some cases the integer value 0 was passed as checksafe parameter
instead of the correct enum value SAFE_CRLF_FALSE. That was no problem
because SAFE_CRLF_FALSE is defined as 0.
FALSE/FAIL/WARN are different from RENORMALIZE and KEEP_CRLF. Therefore,
an enum is not ideal. Let's use a integer bit pattern instead and rename
the parameter to conv_flags to make it more generically usable. This
allows us to extend the bit pattern in a subsequent commit.
