If an error is hit during filefrag operation, it will continue to run
(if multiple files are specified on the command-line), but will exit
with a non-zero value, so that callers can determine that some error
was hit.
Clean up the printing of FIEMAP flags and print some newer flags that
were missing. Also print unknown flags as hex values.

Fix a file handle leak for the target file in copy_file() when error
handlers return without closing the file. Instead, clean up at the
end of the function to handle cleanup in normal and error cases.

The strptime() function does not update fields in struct tm that are
not specified in the input format. The glibc implementation sets the
tm_yday field (%j) when any of the year (%Y), month (%m), or day (%d)
fields are changed, but the MacOS strptime() does not set tm_yday in
this case. This caused string_to_time() to calculate the wrong Unix
epoch on MacOS. If tm_yday is unset, compute it in string_to_time().
This also fixes test regression failures for FreeBSD.

The commit:
802146c mke2fs: create a regular file if necessary
caused a regression on 32-bit machines; the open() fails if
the file size is > 4G.
Using ext2fs_open_file() fixes it.

There are interfaces that are used by mke2fs.c and tune2fs.c which are
in quotaio.h, and some future changes will be much simpler if we can
combine the two header files together. Also the guard #ifdef for
mkquota.h was incorrect, which caused problems when both header files
needed to be included.
Also remove quota.pc and installation rules for libquota, since this
library is never going to be something that we can export externally
anyway. Eventually we'll want to clean up the interfaces and move the
external publishable interfaces to the libext2fs library, and then
rename what's left from libquota.a to libsupport.a for internal use
only.

The quota_handle wasn't getting closed in quota_compare_and_update().
Fix this, and also make sure that quota_file_close() doesn't
unnecessarily modify the quota inode if it's not necessary. Otherwise
e2fsck will claim that the file system is modified when it didn't need
to be.

Previously if there was a missing quota entry --- i.e., if there were
files owned by group "eng", but there was no quota record for group
"eng", e2fsck would not notice the missing entry. This means that the
usage informtion would not be properly repaired. This is unfortunate.
Fix this by marking each quota record in quota_dict that has a
corresponding record on disk, and then check to see if there are any
records in quota_dict that have not been marked as having been seen.
In that case, we know we need to update the relevant quota inode.

In scan_dquota_callback() we were copying dqb_off from the on-disk
dquot structure to the dqot structure that we have constructed in
memory. This is a bad idea, because if we detect that the quota inode
is corrupted and needs to be replaced, when we later write out the
inode, the fact that we have a non-zero dqb_off value means that quota
routines will not bother updating the quota tree index, since
presumably the quota tree index already has an entry for this dqot.
The problem is that e2fsck, the only user of these functions, has
zapped the quota inode so it can be written from scratch. So this
means the index for the quota records are not written out, so the
kernel can not find any of the records in the quota inodes. Oops.
The fix is simple; there is no reason to copy the dqb_off field into
the quota_dict copy of struct dquot.

The combination of 128-byte inodes and inline_data is silly, since
there's no room in the inode table. Unfortunately, if neither
mke2fs.conf nor the mkfs command line options specify an inode size,
the default inode size is set to 128 bytes (by libext2fs) and the
warning isn't printed. Therefore, always do the check-and-warning.

The checking of types in parse-types.sh doesn't make much sense in a
cross-compilation environment, because the generated binary is
executed on build machine.
So even if asm_types.h has got correct statements for types, it's
possible that the generated binary will report an error, because these
types are for the target machine.
