We use "test-tool string-list remove_duplicates" to test the
"string_list_remove_duplicates" function. As we have introduced the unit
test, we'd better remove the logic from shell script to C program to
improve test speed and readability.
As all the tests in shell script are removed, let's just delete the
"t0063-string-list.sh" and update the "meson.build" file to align with
this change.
Also we could simply remove "DISABLE_SIGN_COMPARE_WARNINGS" due to we
have already deleted related code.
Unfortunately, we cannot totally remove "test-string-list.c" due to that
we would test the performance of sorting about string list by executing
"test-tool string-list sort" in "p0071-sort.sh".

We use "test-tool string-list filter" to test the "filter_string_list"
function. As we have introduced the unit test, we'd better remove the

We rely on "test-tool string-list" command to test the functionality of
the "string-list". However, as we have introduced clar test framework,
we'd better move the shell script into C program to improve speed and
readability.
Create a new file "u-string-list.c" under "t/unit-tests", then update
the Makefile and "meson.build" to build the file. And let's first move
"test_split" into unit test and gradually convert the shell script into
C program.
In order to create `string_list` easily by simply specifying strings in
the function call, create "t_vcreate_string_list_dup" function to do
this.
Then port the shell script tests to C program and remove unused
"test-tool" code and tests.

Mark code units that generate warnings with `-Wsign-compare`. This
allows for a structured approach to get rid of all such warnings over
time in a way that can be easily measured.

Enhance `string_list_split_in_place()` to accept multiple characters as
delimiters instead of a single character.
Instead of using `strchr(2)` to locate the first occurrence of the given
delimiter character, `string_list_split_in_place_multi()` uses
`strcspn(2)` to move past the initial segment of characters comprised of
any characters in the delimiting set.
When only a single delimiting character is provided, `strpbrk(2)` (which
is implemented with `strcspn(2)`) has equivalent performance to
`strchr(2)`. Modern `strcspn(2)` implementations treat an empty
delimiter or the singleton delimiter as a special case and fall back to
calling strchrnul(). Both glibc[1] and musl[2] implement `strcspn(2)`
this way.
This change is one step to removing `strtok(2)` from the tree. Note that
`string_list_split_in_place()` is not a strict replacement for
`strtok()`, since it will happily turn sequential delimiter characters
into empty entries in the resulting string_list. For example:
string_list_split_in_place(&xs, "foo:;:bar:;:baz", ":;", -1)
would yield a string list of:
["foo", "", "", "bar", "", "", "baz"]
Callers that wish to emulate the behavior of strtok(2) more directly
should call `string_list_remove_empty_items()` after splitting.
To avoid regressions for the new multi-character delimter cases, update
t0063 in this patch as well.

Add a sort command to test-string-list that reads lines from stdin,
stores them in a string_list and then sorts it. Use it in a simple
perf test script to measure the performance of string_list_sort().
