Even though the "struct odb_transaction" member is at the beginning
of the containing "struct odb_transaction_files", i.e., at offset 0,
using container_of() to add offset 0 to a NULL pointer gets flagged
as a bad behaviour under SANITIZE=undefined.
Use container_of_or_null() to work around this issue.

The 'flags' and 'track_flags' fields in symlinks.c are used
strictly as a collection of bits (using bitwise operators including
&, |, ~). Using a signed integer for bitmasks may lead to undefined
behavior with shift operations and logic errors if the MSB is touched.
Change these fields from 'int' to 'unsigned int' to match our usage
patterns.

Small clean-up of xdiff library to remove unnecessary data
duplication.
* pw/xdiff-cleanups:
xdiff: remove unused data from xdlclass_t
xdiff: remove "line_hash" field from xrecord_t
When a strip option to the %(refname) placeholder is asked to leave N
path components, we first count up the path components to know how many
to remove. That happens with a loop like this:
/* Find total no of '/' separated path-components */
for (i = 0; p[i]; p[i] == '/' ? i++ : *p++)
;
which is a little hard to understand for two reasons.
First, the dereference in "*p++" is seemingly useless, since nobody
looks at the result. And static analyzers like Coverity will complain
about that. But removing the "*" will cause gcc to complain with
-Wint-conversion, since the two sides of the ternary do not match (one
is a pointer and the other an int).
Second, it is not clear what the meaning of "p" is at each iteration of
the loop, as its position with respect to our walk over the string
depends on how many slashes we've seen. The answer is that by itself, it
doesn't really mean anything: "p + i" represents the current state of
our walk, with "i" counting up slashes, and "p" by itself essentially
meaningless.
None of this behaves incorrectly, but ultimately the loop is just
counting the slashes in the refname. We can do that much more simply
with a for-loop iterating over the string and a separate slash counter.
We can also drop the comment, which is somewhat misleading. We are
counting slashes, not components (and a comment later in the function
makes it clear that we must add one to compensate). In the new code it
is obvious that we are counting slashes here.

Two tests in t6006 depend on the iconv(1) prerequisite to reencode a
commit message. This executable may not even exist though in case the
prereq is not set, which will cause the tests to fail.
Fix this by using UTF-8 instead when the prereq is not set.

We've got a bunch of tests in t5550 that connect to "$HTTPD_URL/error"
to ensure that error messages are properly forwarded. This URL executes
the "t/lib-httpd/error.sh" script, which in turn depends on the iconv(1)
executable to reencode the message.
This executable may not exist on platforms, which will make the tests
fail. Guard them with the ICONV prereq to fix such failures.

In t4205 we have a bunch of tests that depend on the iconv prereq. This
is for most of the part because we format commit messages that have been
encoded in an encoding different than UTF-8.
Those tests fall into two classes though:
- One class of tests outputs the data as-is without reencoding.
- One class of tests outputs the data with "i18n.logOutputEncoding" to
reencode it.
Curiously enough, both of these classes are marked with the ICONV
prereq, even though one might expect that the first class wouldn't need
the prereq. This is because we unconditionally use ISO-8859-1 encoding
for the initial commit message, and thus we depend on converting to
UTF-8 indeed.
This creates another problem though: when the iconv(1) executable does
not exist the test setup fails, even in the case where the ICONV prereq
has not been set.
Fix these issues by making the test encoding conditional on ICONV: if
it's available we use ISO-8859-1, otherwise we use UTF-8. This fixes the
test setup on platforms without iconv(1), and it allows us to drop the
ICONV prereq from a bunch of tests.
