e2fsck: allow deleting or zeroing shared blocks
E2fsck fixes files that are found to be sharing blocks by cloning
the shared blocks and giving each file a private copy in pass 1D.
Allowing all files claiming the shared blocks to have copies can
inadvertantly bypass access restrictions. Deleting all the files,
zeroing the cloned blocks, or placing the files in the /lost+found
directory after cloning may be preferable in some secure environments.
The following patches implement config file and command line options
in e2fsck that allow pass 1D behavior to be tuned according to site
policy. It adds two extended options and config file counterparts.
On the command line:
-E clone=dup|zero
Select the block cloning method. "dup" is old behavior,
and is the default. "zero" is a new method that substitutes
zero-filled blocks for the shared blocks in all the files
that claim them.
-E shared=preserve|lost+found|delete
Select the disposition of files containing shared blocks.
"preserve" is the old behavior which remains the default.
"lost+found" causes files to be unlinked after cloning so
they will be reconnected to /lost+found in pass 3.
"delete" skips cloning entirely and simply deletes the files.
In the config file:
[options]
clone=dup|zero
shared=preserve|lost+found|delete

tests: use make rules to run tests in parallel
Change the e2fsck/mke2fs/tune2fs/e2image/debugfs regression tests
to be driven by Makefile rules instead of by a script loop. This
allows the tests to be run in parallel like a build and reduces
testing time significantly.
One major change to the tests themselves is to printing the test
name, description, and status together after the test has passed
or failed, to avoid mixing lines from the tests. The other major
change is to use unique filenames for each test, which was mostly
handled already via
b4db1e4c7461a50e18c9fd135b9f1ba6f27e4390, but
in some cases temporary files are changed to use $test_name.tmp to
avoid any collision between running tests.
On my old 2-CPU system it reduced the testing time from 160s to 40s.
Most of the savings is running the MMP test delays going in parallel,
but it still takes the length of the slowest test, f_mmp_garbage.
There will be ongoing benefit in the future as more tests are added
since the wallclock time will not substantially increase.
Tests were run with "make -j", "make -j4", "make -j12", "make -j16",

libext2fs: don't inline ext2fs_open_file() and ext2fs_stat()
The creation of inline wrappers ext2fs_open_file() and ext2fs_stat()
in commit
c859cb1de0d624caa0779fb17d1a53766143136e in ext2fs.h caused
difficulties with the use of headers, since the headers for open64()
and stat64() may already be included (and skip the declaration of the
64-bit variants) before ext2fs.h is ever read. There is no real way
to solve the missing prototypes and resulting compiler warnings inside
ext2fs.h.
Since ext2fs_open_file() and ext2fs_stat() are not performance
critical operations, they do not need to be inline functions at all,
and the needed function headers can be handled properly in one file.
Similarly, posix_memalloc() was having difficulties with headers, and
was being defined in ext2fs.h, but it is now only being used by a
single file, so move the required header there.

The quotactl() system call was being used without the use of a

e2fsck: fix checks done for mounted vs. read-only
Currently, if e2fsck is run without the "-n" flag (i.e. it
might modify the filesystem), there is no guarantee that it will
open the filesystem with the EXCLUSIVE flag (i.e. O_EXCL) to
prevent the block device from being checked (in most cases this
means mounted, but it could also be an MD/LVM member device).
Conversely, if e2fsck is run with "-n" (i.e. read-only), and
/etc/mtab or /proc/mounts does not report the block device as
mounted then e2fsck thinks the filesystem is unmounted. In this
case, e2fsck incorrectly sets the EXCLUSIVE flag, which causes
the check to fail, even though e2fsck is running read-only.
To fix this, do not open with EXCLUSIVE if it is a read-only check,
and always open with EXCLUSIVE if the filesystem might be changed.
This also prevents filesystem mounts while e2fsck is running.
Also refuse allow e2fsck to run at all if the filesystem is BUSY.
The e2fsck check_mount() was checking for MOUNTED, but not BUSY,
and it should refuse to run outright if the block device is BUSY.
The previous MOUNTED heuristics pre-date the O_EXCL reservation
by the kernel, so there could be uncertainty due to stale /etc/mtab
data, but with newer kernels a busy device should never be modified.

Support systems without posix_memalign() and memalign()
MacOS 10.5 doesn't have posix_memalign() nor memalign(), but it does

so I've added support for a good-enough emulation of memalign()'s
functionality using valloc(), with an explicit test to make sure
valloc() is returning a pointer which is sufficiently aligned given
the requested alignment. This won't work if you try to operate on a
file system with a 16k blocksize using an e2fsprogs built on MacOS
10.5 system, but it is good enough for the common case of 4k
blocksize file systems, and we will let the memory allocation fail in
the alignment is not good enough.
I've also added a unit test for ext2fs_get_memalign() so we can be
sure it's working as expected. I've tested the code paths with
HAVE_POSIX_MEMALIGN defined, HAVE_POSIX_MEMALIGN undefined, and
HAVE_POSIX_MEMALIGN and HAVE_MEMALIGN undefined on an x86 Linux
