e2fsck: print thread log properly
When multi-thread fsck is enabled, logs printed from multiple
threads could overlap with each other. The overlap sometimes
makes the logs unreadable because log_out() is used multiple times
for a single line.
This patch adds leading [Thread XXX] to each logs if multi-thread
is enabed by -m option.
This patch also adds message to show the group ranges and inode
numbers for each thread, which is useful for debuging multi-thread
check.

LU-17310 tests: make m_assume_storage_prezeroed more robust
Don't assume that mke2fs is going to zero out an exact number
of blocks when run with/without "-E assume_storage_prezeroed",
since this depends on a number of different options that are
not specified in the test script.
Instead, check that the number of blocks zeroed in the image is
a small fraction (1/15th) of the number of blocks zeroed when
"-E assume_storage_prezeroed" is not given, which makes it more
robust when running in different environments. This varies from
1/16 in the original test to 1/91 in my local test environment.
Avoid "losetup --sector-size 4096", use "mke2fs -b 4096" instead.
Clean up the loop device before checking "stat" so that all
blocks are flushed to the backing storage before calling sync.
Only one loop device and test file is needed for the test.

AOSP: Use no_full_install: true instead of installable: false
So far, we have used `instalable: false` to avoid collision with the
other modules that are installed to the same path. A typical example was
<foo> and <foo>.microdroid. The latter is a modified version of the
former for the inclusion of the microdroid image. They however both have
the same instalation path (ex: system/bin) and stem (ex: foo) so that we
can reference them using the same path regardless of whether we are in
Android or microdroid.
However, the use of `installable: false` for the purpose is actually
incorrect, because `installable: false` also means, obviously, "this
module shouldn't be installed". The only reason this incorrect way has
worked is simply because packaging modules (ex: android_filesystem)
didn't respect the property when gathering the modules.
As packaging modules are now fixed to respect `installable: false`, we
need a correct way of avoiding the collision. `no_full_install: true` is
it.
If a module has this property set to true, it is never installed to the
full instal path like out/target/product/<partition>/... It can be
installed only via packaging modules.

AOSP: ext2simg: fix off-by-one errors causing corruption
The chunk_end parameter to add_chunk() is exclusive, but two callers
incorrectly treat it as inclusive: when the maximum chunk length of
'INT32_MAX - 12' bytes is reached, and when a chunk extends to the very
end of the filesystem. The result is that the output simg file contains
zeroes for the last block of these chunks instead of the correct data.
A related bug is that the expanded size of the simg file is set to the
filesystem size (in blocks) minus s_first_data_block. On filesystems
where s_first_data_block != 0, i.e. 1K blocksize filesystems without
bigalloc enabled, this truncates the last block of the filesystem.
Fix these bugs by (a) making add_chunk() take the chunk length and
passing the correct values, and (b) using the filesystem size properly.
Here is a reproducer that shows the last block of the filesystem being
truncated (bsize=1024) and being corrupted with zeroes (bsize=4096):

AOSP: Mostly restore -Werror for macOS build
It turns out the "Can't use getmntent or getmntinfo" warning was the
only warning remaining in the macOS build via the Android build system.
So now that it's fixed, -Wno-error can be removed.
That being said, the upstream CI (GitHub Actions) currently uses
-Wno-error=deprecated-declarations for the macOS build, since it's still
needed for some files (which aren't built by the Android build system).
For now, let's just replace -Wno-error with
-Wno-error=deprecated-declarations to match what the upstream CI uses.

AOSP: Revert "Android: stop suppressing warnings from macOS build"
Unfortunately, the macOS build is not tested either by presubmit or by
local builds. A macOS build *is* being tested in the upstream GitHub
Actions workflow now; however, that uses the autotools-based build
system, and there can be issues specific to the Android build system.
As a result, removing -Wno-error was not safe yet, and the macOS build
is currently broken in postsubmit. As there could be multiple issues,
let's restore -Wno-error until I've had a chance to fix the warnings.

mke2fs: implement timestamp clamping if SOURCE_DATE_EPOCH is set
When copying files to the newly created file system using "mke2fs -d",
and there are timestamps greater than what is specified by
SOURCE_DATE_EPOCH, clamp the timestamp to the SOURCE_DATE_EPOCH
timestamp.

libext2fs: use a safe_getenv() function everywhere
Hoist safe_getenv() from test_io.c and unix_io.c to a globally
exported ext2fs_safe_getenv() and use it instead of getenv() in
libext2fs. This provides a bit more safety if e2fsprogs programs are
used in setuid contexts.

Fix coverity false positives introduced by the post-2038 changes
Commit
ca8bc9240a00 ("Add post-2038 timestamp support...") did things
like casting a 64-bit unsigned integer into a signed 32-bit integer
deliberately; but Coverity thinks this is a bug. So mask off the bits
to make it clear this was deliberate.

e2fsck: make sure get_backup_sb() works when ctx is NULL
The print_e2fsck_message() function can call get_backup_sb() with the
ctx variable set to NULL. In that case, we can't dereference
ctx->filesystem_name; instead, we can get the size of the file system
from the ext2fs_block_count(fs->super).

Align function prototypes for libss's request handler function
Clang 17's Undefined Behaviour Sanitizer will throw run-time warnings
if a function pointer is dereferenced with a different function
signature than one in the pointer --- even if the difference is a
missing const qualifier. To fix regression test failures, change
declarations of argv to use ss_argv_t instead of an inconsistently
open-coded type.
