e2mmpstatus is a Multi-Mount Protection (MMP) helper utility to read
an MMP block to see if it is being updated. It can also output the
latest update time, nodename, and device from the MMP block.
This is useful for HA and other maintenance scripts to determine if
the filesystem is in use on another node, and which node it is.

Moved e2mmpstatus checking/dumping code to be part of dumpe2fs rather
than a standalone program, using the "-m" option to check MMP status,
and "-i" to dump info. If dumpe2fs is called as "e2mmpstatus" (and
also "mmpstatus" for compatibility reasons), assume "-m" is specified.
Re-use the existing MMP block handing routines (with some changes) to
check and dump the MMP block, rather than adding duplicate versions.
Modify dumpe2fs to exit with a non-zero error code if there is an
error while reading the filesystem metadata or MMP block, or if
"-m" is used with the "mmp" feature and is in use by another node.
Add a configure check for gethostname() rather than depending on
_BSD_SOURCE or _XOPEN_SOURCE to be set.
Update the f_mmp, m_mmp, m_mmp_bad_csum, and m_mmp_bad_magic tests
to use e2mmpstatus to check and dump the MMP state before and after
e2fsck is run to verify that the tool is working correctly.

If the TEST_BITS file is sparse, then the "debugfs -R write"
command may skip holes in the file when copying it into the
test image (depending on whether SEEK_HOLE/SEEK_DATA and/or
FIEMAP are available in the copy_file() function).
This was causing test failures on MacOS in the f_dup_resize
and d_loaddump tests because the TEST_BITS file was the
compiled "debugfs" binary, which apparently has holes when
built on MacOS, and the number of blocks allocated in the
test image was reduced as a result. This caused the expect
output to differ in the summary line and resulted in failure.
Instead of using the debugfs binary for TEST_BITS, generate
a temporary file using /dev/urandom, if available. If not,
fall back to the old behaviour or using debugfs.
[ Fixed up use of non-POSIX /bin/sh constructs and add test_data.tmp to
.gitignore and files to be deleted on a make clean. --tytso ]

Don't print a verbose configure error in parse-types.h if
<asm/types.h> missing and __[SU]*_TYPEDEF is unset. This is
always the case for non-Linux builds.
The printf formatting strings all use "%llu" for printing 64-bit
values and this it produces a large number of warnings if __u64
is defined as "unsigned long". If __U64_TYPEDEF isn't set use
"unsigned long long" for __u64 in ext2-types.h and blkid-types.h
by default instead of using "unsigned long".
Fix a few places where "%d" or "%u" or "%Lu" were used to print a
64-bit value, by converting them to use "%lld" or "%llu" instead.
Fix a few places where "%lu" was used to print .tv_usec, by casting
the variable to "(long)" since .tv_usec is "int" on some systems.

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 temporary filenames for each test, which was mostly handled
already via b4db1e4c74, 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.
Much of the savings is from the MMP test delays running in parallel.
It still takes the time of the slowest test, f_mmp_garbage, though
there will be ongoing benefit in the future as more tests are added
since the wallclock time will not increase linearly for each test.
Tests were run with various combinations of "make -j", and "make -j2"
through "make -j44" repeatedly without any test failures.
