The undefined behavior sanitizer complains about unaligned

practice. It's possible that they _are_ a problem, of
course, but since it's a known tradeoff the UBSan errors are
just noise.

You can already build and test with ASan by doing:
make CFLAGS=-fsanitize=address test
but there are a few slight annoyances:
1. It's a little long to type.
2. It override your CFLAGS completely. You'd probably
still want -O2, for instance.
3. It's a good idea to also turn off "recovery", which
lets the program keep running after a problem is
detected (with the intention of finding as many bugs as
possible in a given run). Since Git's test suite should
generally run without triggering any problems, it's
better to abort immediately and fail the test when we
do find an issue.
With this patch, all of that happens automatically when you
run:
make SANITIZE=address test

By default, ASan will exit with code 1 when it sees an
error. This means we'll notice a problem when we expected
git to succeed, but not in a test_must_fail block.
Let's ask it to actually raise SIGABRT instead. That will
give us a signal death that test_must_fail will notice. As a
bonus, it may also leave a coredump, which can be handy for
digging into a failure.

We turn off ASan's leak detection by default in the test
suite because it's too noisy. But we don't do so until
part-way through test-lib. This is before we've run any
tests, but after we do our initial "./git" to see if the
binary has even been built.
When built with clang, this seems to work fine. However,
using "gcc -fsanitize=address", the leak checker seems to
complain more aggressively:
$ ./git
...
==5352==ERROR: LeakSanitizer: detected memory leaks

#7 0x7f120dabd2b0 in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x202b0)
This is a leak in the sense that we never free it, but it's
in a global that is meant to last the whole program. So it's
not really interesting or in need of fixing. And at any
rate, mentioning leaks outside of the test_expect blocks is
certainly unwelcome, as it pollutes stderr.
Let's bump the setting of ASAN_OPTIONS higher in test-lib.sh
to catch our initial "can we even run git?" test. While
we're at it, we can add a comment to make it a bit less
inscrutable.

Store the pointer to the string allocated by shorten_unambiguous_ref in
a dedicated variable, short_base, and keep base unchanged. A non-const
variable is more appropriate for such an object. It avoids having to
cast const away on free and stops redefining the meaning of base, making
the code slightly clearer.

The values in struct throughput are only updated every 0.5 seconds. If
we're all done before that time span then the final update will show a
rate of 0 bytes/s, which is misleading if some bytes had been handled.
Remember the start time and show the total throughput instead.
And avoid division by zero by enforcing a minimum time span value of 1
(unit: 1/1024th of a second). That makes the resulting rate an
underestimation, but it's closer to the actual value than the currently
shown 0 bytes/s.

Since 949af0684 (branch: use ref-filter printing APIs,
2017-01-10), git-branch's output is generated by passing a
custom format to the ref-filter code. This format forgot to
pass BRANCH_COLOR_LOCAL, meaning that local branches
(besides the current one) were never colored at all.
We can add it in the %(if) block where we decide whether the
branch is "current" or merely "local". Note that this means
the current/local coloring is either/or. You can't set:
[color "branch"]
local = blue
current = bold
and expect the current branch to be "bold blue". This
matches the pre-949af0684 behavior.

When assembling the ref-filter format to show "git branch"
output, we put the "%(if)%(HEAD)" conditional at the start
of the overall format. But there's no point in checking
whether a remote branch matches HEAD, as it never will.
The check should go inside the local conditional; we
assemble that format inside the "local" strbuf.
By itself, this is just a minor optimization. But in a
future patch, we'll need this refactoring to fix
local-branch coloring.

When we encounter an error adding reflogs for a walk, we try
to free any logs we have read. But we didn't free all
fields, meaning that we could in theory leak all of the
"items" array (which would consitute the bulk of the
allocated memory).
This patch adds a helper which frees all of the entries and
uses it as appropriate.
As it turns out, the leak seems impossible to trigger with
the current code. Of the three error paths that free the
complete_reflogs struct, two only kick in when the items
array is empty, and the third was removed entirely in the
previous commit.
So this patch should be a noop in terms of behavior, but it
fixes a potential maintenance headache should anybody add a
new error path and copy the partial-free code. Which is
what happened in 5026b47175 (add_reflog_for_walk: avoid
memory leak, 2017-05-04), though its leaky call was the
third one that was recently removed.
