As the option name suggests this does make things slower, e.g. for

Benchmark 2: LSAN_OPTIONS=fast_unwind_on_malloc=1 make T=t0001-init.sh

1.08 ± 0.03 times faster than 'LSAN_OPTIONS=fast_unwind_on_malloc=0 make T=t0001-init.sh'
I think that's more than worth it to get the more meaningful stack

one-off "fast" runs.

Change the GIT_BUILD_DIR from a path like "/path/to/build/t/.." to
"/path/to/build". The "TEST_DIRECTORY" here is already made an
absolute path a few lines above this.
We could simply do $(cd "$TEST_DIRECTORY"/.." && pwd) here, but as
noted in the preceding commit the "$TEST_DIRECTORY" can't be anything
except the path containing this test-lib.sh file at this point, so we
can more cheaply and equally strip the "/t" off the end.
This change will be helpful to LSAN_OPTIONS which will want to strip
the build directory path from filenames, which we couldn't do if we
had a "/.." in there.

Correct a misleading comment added by me in 62f539043c (test-lib:
Allow overriding of TEST_DIRECTORY, 2010-08-19), and add an assertion
that TEST_DIRECTORY cannot point to any directory except the "t"
directory in the top-level of git.git.
This assertion is in effect not new, since we'd already die if that
wasn't the case[1], but it and the updated commentary help to make
that clearer.
The existing comments were also on the wrong arms of the
"if". I.e. the "allow tests to override this" was on the "test -z"
arm. That came about due to a combination of 62f539043c and
85176d7251 (test-lib.sh: convert $TEST_DIRECTORY to an absolute path,
2013-11-17).
Those earlier comments could be read as allowing the "$TEST_DIRECTORY"
to be some path outside of t/. As explained in the updated comment
that's impossible, rather it was meant for *tests* that ran outside of
t/, i.e. the "t0000-basic.sh" tests that use "lib-subtest.sh".
Those tests have a different working directory, but they set the
"TEST_DIRECTORY" to the same path for bootstrapping. The comments now
reflect that, and further comment on why we have a hard dependency on
this.

Change our ASAN_OPTIONS and LSAN_OPTIONS to set defaults for those
variables, rather than punting out entirely if we already have them in
the environment.
We want to take any user-provided settings over our own, but we can do
that by prepending our defaults to the variable. The libsanitizer
options parsing has "last option wins" semantics.
It's now possible to do e.g.:
LSAN_OPTIONS=report_objects=1 ./t0006-date.sh
And not have the "report_objects=1" setting overwrite our sensible
default of "abort_on_error=1", but by prepending to the list we ensure
that:
LSAN_OPTIONS=report_objects=1:abort_on_error=0 ./t0006-date.sh
Will take the desired "abort_on_error=0" over our default.
See b0f4c9087e (t: support clang/gcc AddressSanitizer, 2014-12-08)
for the original pattern being altered here, and
85b81b35ff (test-lib: set LSAN_OPTIONS to abort by default,
2017-09-05) for when LSAN_OPTIONS was added in addition to the
then-existing ASAN_OPTIONS.

In sparse-checkout add/set under cone mode, the arguments passed are
supposed to be directories rather than gitignore-style patterns.
However, given the amount of effort spent in the manual discussing
patterns, it is easy for users to assume they need to pass patterns such
as
/foo/*
or
!/bar/*/
or perhaps they really do ignore the directory rule and specify a
random gitignore-style pattern like
*.c
To help catch such mistakes, throw an error if any of the positional
arguments:
* starts with any of '/!'
* contains any of '*?[]'
Inform users they can pass --skip-checks if they have a directory that
really does have such special characters in its name. (We exclude '\'
because of sparse-checkout's special handling of backslashes; see
the MINGW test in t1091.46.)

The set and add subcommands accept multiple positional arguments.
The meaning of these arguments differs slightly in the two modes:
Cone mode only accepts directories. If given a file, it would
previously treat it as a directory, causing not just the file itself to
be included but all sibling files as well -- likely against users'
expectations. Throw an error if the specified path is a file in the
index. Provide a --skip-checks argument to allow users to override
(e.g. for the case when the given path IS a directory on another
branch).
Non-cone mode accepts general gitignore patterns. There are many
reasons to avoid this mode, but one possible reason to use it instead of
cone mode: to be able to select individual files within a directory.
However, if a file is passed to set/add in non-cone mode, you won't be
selecting a single file, you'll be selecting a file with the same name
in any directory. Thus users will likely want to prefix any paths they
specify with a leading '/' character; warn users if the patterns they
specify exactly name a file because it means they are likely missing
such a leading slash.

In cone mode, non-option arguments to set & add are clearly paths, and
as such, we should pay attention to prefix.
In non-cone mode, it is not clear that folks intend to provide paths
since the inputs are gitignore-style patterns. Paying attention to
prefix would prevent folks from doing things like
git sparse-checkout add /.gitattributes
git sparse-checkout add '/toplevel-dir/*'
In fact, the former will result in
fatal: '/.gitattributes' is outside repository...
while the later will result in
fatal: Invalid path '/toplevel-dir': No such file or directory
despite the fact that both are valid gitignore-style patterns that would
select real files if added to the sparse-checkout file. This might lead
people to just use the path without the leading slash, potentially
resulting in them grabbing files with the same name throughout the
directory hierarchy contrary to their expectations. See also [1] and
[2]. Adding prefix seems to just be fraught with error; so for now
simply throw an error in non-cone mode when sparse-checkout set/add are
run from a subdirectory.
