* a bug in "git fetch"'s s_update_ref, which trusts the result of an
errno == ENOTDIR check to detect D/F conflicts
ENOTDIR makes sense as a sign that a file was in the way of a
directory we wanted to create. Should "git fetch" also look for
ENOTEMPTY or EEXIST to catch cases where a directory was in the way
of a file to be created?

refs.c: add a strbuf argument to ref_transaction_commit for error logging
Add a strbuf argument to _commit so that we can pass an error string back to
the caller. So that we can do error logging from the caller instead of from
_commit.
Longer term plan is to first convert all callers to use onerr==QUIET_ON_ERR
and craft any log messages from the callers themselves and finally remove the
onerr argument completely.

refs.c: allow passing NULL to ref_transaction_free
Allow ref_transaction_free(NULL) as a no-op. This makes ref_transaction_free
easier to use and more similar to plain 'free'.
In particular, it lets us rollback unconditionally as part of cleanup code
after setting 'transaction = NULL' if a transaction has been committed or
rolled back already.

refs.c: constify the sha arguments for ref_transaction_create|delete|update
ref_transaction_create|delete|update has no need to modify the sha1
arguments passed to it so it should use const unsigned char* instead
of unsigned char*.
Some functions, such as fast_forward_to(), already have its old/new
sha1 arguments as consts. This function will at some point need to
use ref_transaction_update() in which case this change is required.

We do not yet need both a rollback and a free function for transactions.
Remove ref_transaction_rollback and use ref_transaction_free instead.
At a later stage we may reintroduce a rollback function if we want to start
adding reusable transactions and similar.

Patch id changes if users reorder file diffs that make up a patch.
As the result is functionally equivalent, a different patch id is
surprising to many users.
In particular, reordering files using diff -O is helpful to make patches
more readable (e.g. API header diff before implementation diff).
Add an option to change patch-id behaviour making it stable against
these kinds of patch change:
calculate SHA1 hash for each hunk separately and sum all hashes
(using a symmetrical sum) to get patch id
We use a 20byte sum and not xor - since xor would give 0 output
for patches that have two identical diffs, which isn't all that
unlikely (e.g. append the same line in two places).
The new behaviour is enabled
- when patchid.stable is true
- when --stable flag is present
Using a new flag --unstable or setting patchid.stable to false force
the historical behaviour.
In the documentation, clarify that patch ID can now be a sum of hashes,
not a hash.
Document how command line and config options affect the
behaviour.

string-list: spell all values out that are given to a string_list initializer
STRING_LIST_INIT_{NODUP,DUP} initializers list values only
for earlier structure members, relying on the usual
convention in C that the omitted members are initailized to
0, i.e. the former is expanded to the latter:
struct string_list l = STRING_LIST_INIT_DUP;
struct string_list l = { NULL, 0, 0, 1 };
and the last member that is not mentioned (i.e. 'cmp') is
initialized to NULL.
While there is nothing wrong in this construct, spelling out
all the values where the macros are defined will serve also
as a documentation, so let's do so.
