Simplify flow within loop: first decide whether to keep the reference,
then keep/free it. This makes it clearer that each ref has exactly
two possible destinies, and removes duplication of the code for
appending the reference to the linked list.

Instead of temporarily storing matched refs to temporary array
"return_refs", simply append them to newlist as we go. This changes
the order of references in newlist to strictly sorted if "--all" and
"--depth" and named references are all specified, but that usage is
broken anyway (see the last two tests in t5500).
This changes the last test in t5500 from segfaulting into just
emitting a spurious error (this will be fixed in a moment).

Remove any references that are available from the remote from the
sought list (rather than overwriting their names with NUL characters,
as previously). Mark matching entries by writing a non-NULL pointer
to string_list_item::util during the iteration, then use
filter_string_list() later to filter out the entries that have been
marked.
Document this aspect of fetch_pack() in a comment in the header file.
(More documentation is obviously still needed.)

fetch_pack() removes duplicates from the "sought" list, thereby
shrinking the list. But previously, the caller was not informed about
the shrinkage. This would cause a spurious error message to be
emitted by cmd_fetch_pack() if "git fetch-pack" is called with
duplicate refnames.
Instead, remove duplicates using string_list_remove_duplicates(),
which adjusts sought->nr to reflect the new length of the list.
The last test of t5500 inexplicably *required* "git fetch-pack" to
fail when fetching a list of references that contains duplicates;
i.e., it insisted on the buggy behavior. So change the test to expect
the correct behavior.

Once a match has been found at sought_pos, the entry is zeroed and no
future attempts will match that entry. So increment sought_pos to
avoid checking against the zeroed-out entry during the next iteration.

Document some bugs in "git fetch-pack":
1. If "git fetch-pack" is called with "--all", "--depth", and an
explicit existing non-tag reference to fetch, then it falsely reports
that the reference was not found, even though it was fetched
correctly.
2. If "git fetch-pack" is called with "--all", "--depth", and an
explicit existing tag reference to fetch, then it segfaults in
filter_refs() because return_refs is used without having been
initialized.

Add two new functions, string_list_split() and
string_list_split_in_place(). These split a string into a string_list
on a separator character. The first makes copies of the substrings
(leaving the input string untouched) and the second splits the
original string in place, overwriting the separator characters with
NULs and referring to the original string's memory.
These functions are similar to the strbuf_split_*() functions except
that they work with the more powerful string_list interface.

When a path being merged is auto detected to be a binary file, we
warned "Cannot merge binary files" before switching to activate the
binary ll-merge driver. When we are merging with the -Xours/theirs
option, however, we know what the "clean" merge result is, and the
warning is inappropriate.
In addition, when the path is explicitly marked as a binary file,
this warning was not issued, even though without -Xours/theirs, we
cannot cleanly automerge such a path, which was inconsistent.
Move the warning code from ll_xdl_merge() to ll_binary_merge(), and
issue the message only when we cannot cleanly automerge.

"git blame file" has always meant "find the origin of each line of
the file in the history leading to HEAD, oh by the way, blame the
lines that are modified locally to the working tree".
This teaches "git blame" that during a conflicted merge, some
uncommitted changes may have come from the other history that is
being merged.
The verify_working_tree_path() function introduced in the previous
patch to notice a typo in the filename (primarily on case insensitive
filesystems) has been updated to allow a filename that does not exist
in HEAD (i.e. the tip of our history) as long as it exists one of the
commits being merged, so that a "we deleted, the other side modified"
case tracks the history of the file in the history of the other side.

checkout operates in three different modes. On top of that it tries to
be smart by guessing the branch name for switching. This results in
messy option handling code. This patch reorders it so that
- cmd_checkout() is responsible for parsing, preparing input and
determining mode
- Code of each mode is in checkout_paths() and checkout_branch(),
where sanity checks are performed
Another slight improvement is always print branch name (or commit
name) when printing errors related ot them. This helps catch the case
where an option is mistaken as branch/commit.
