test-chmtime: Fix exit code on Windows

MinGW's bash does not recognize an exit code -1 as failure. See also
47e3de0e (MinGW: truncate exit()'s argument to lowest 8 bits) and 2488df84
(builtin run_command: do not exit with -1). Exit code 1 is good enough.

t2100: modernize style and unroll a loop of test cases

In particular, move all test preparations inside test_expect_success.

In a subsequent patch, we are going to move test case path3 out of the
loop of test cases. Use this opportunity to linearize the tests.

tests: introduce test_ln_s and test_ln_s_add

Add new functions that create symbolic links and add them to the index to
be used in cases where a symbolic link is not required on the file system.
We will use them to remove many SYMLINKS prerequisites from test cases.

tests: use test_ln_s_add to remove SYMLINKS prerequisite (trivial cases)

There are many instances where the treatment of symbolic links in the
object model and the algorithms are tested, but where it is not
necessary to actually have a symbolic link in the worktree. Make
adjustments to the tests and remove the SYMLINKS prerequisite when
appropriate in trivial cases, where "trivial" means:

- merely a replacement of 'ln -s a b' to test_ln_s or of
  'ln -s a b && git add b' to test_ln_s_add is needed;

- a test for symbolic link on the file system can be split off (and
  remains protected by SYMLINKS);

- existing code is equivalent to test_ln_s[_add].

t0000: use test_ln_s_add to remove SYMLINKS prerequisite

t0000-basic hard-codes many object IDs. To cater to file systems that do
not support symbolic links, different IDs are used depending on the
SYMLINKS prerequisite. But we can observe the symbolic links are only
needed to generate index entries. Use test_ln_s_add to generate the
index entries and get rid of explicit SYMLINKS checks.

This undoes the special casing introduced in this test by 704a3143
(Use prerequisite tags to skip tests that depend on symbolic links,
2009-03-04).

t2100: use test_ln_s_add to remove SYMLINKS prerequisite

One converted case expects 'git update-index' to fail. We cannot use
'test_must_fail test_ln_s_add ...', because that would mistakenly pass
if a command other than the final git-update-index of test_ln_s_add
failed. Hence, use test_ln_s to create the symbolic link and keep
the explicit 'test_must_fail git update-index'.

t3030: use test_ln_s_add to remove SYMLINKS prerequisite

The test cases include many corner-cases of merge-recursive's behavior,
some of them involve type changes and symbolic links. All cases, including
those that are protected by SYMLINKS check only whether the result of
merge-recursive is correctly stored in the database and the index; the
file system is not investigated. Use test_ln_s_add to enter a symbolic
link in the index in the test setup and run the tests without the
SYMLINKS prerequisite.

Notice that one test that has the SYMLINKS protection removed is an
expect_failure. There is a possibility that the test fails differently
depending on whether SYMLINKS is present or not; but this is not the case
presently.

t3509, t4023, t4114: use test_ln_s_add to remove SYMLINKS prerequisite

In t4023 and t4114, we have to remove the entries using 'git rm' because
otherwise the entries that must turn from symbolic links to regular files
would stay symbolic links in the index. For the same reason, we have to
use 'git mv' instead of plain 'mv' in t3509.

t6035: use test_ln_s_add to remove SYMLINKS prerequisite

All tests in t6035 are protected by SYMLINKS. But that is not necessary,
because a lot of the functionality can be tested provided symbolic link
entries enter the index and object data base. Use test_ln_s_add for this
purpose.

Some test cases do test the presence of symbolic links on the file system.
Move these tests into separate test cases that remain protected by
SYMLINKS.

There is one instance of expect_failure. There is a possibility that this
test case fails differently depending on whether SYMLINKS is present or
not; but this is not the case.
