btrfs-progs: lowmem check: Fix false alert about file extent interrupt
As Qu mentioned in this thread
(https://www.spinics.net/lists/linux-btrfs/msg64469.html), compression
can cause regular extent to co-exist with an inlined extent. This
coexistence makes things confusing. Since it is currently allowed and
can appear in a filesystem, fix btrfsck to prevent a bunch of error
reports to appear that will make user feel uneasy.
When checking a file extent, record the extent_end of the regular extent
to check if there is a gap between the regular extents. Normally there
is only one inlined extent, so the extent_end of inlined extent is
useless. However, if a regular extent can co-exist with an inlined
extent, the extent_end of the inlined extent also needs to be recorded.

While iterating over backrefs in repair_inode_backrefs, there are
several situations to repair one backref according
backref->found_dir_item and backref->found_dir_index. Two of these
branches may free the backref, but next checks will still access the
freed memory.
Because these branches are independent, let repair_inode_backrefs skip
to handle next backref after free can fix it.

Fuzzed image bko-156811-bad-parent-ref-qgroup-verify.raw causes qgroup

But the fact is, such image is heavily damaged so there is no valid root
item for the extent tree.
Normal extent tree key in root tree should be (EXTENT_TREE ROOT_ITEM 0),
while in that fuzzed image, we got (EXTENT_TREE EXXTENT_DATA SOME_NUMBER).
It's btrfs_find_last_root() that only checks the objectid, not caring

btrfs-progs: tests: Fix fuzz-test for bko-161821.raw.txt
Fuzzed image bko-161821.raw causes btrfs check to get segmentation fault.
The function check_owner_ref attempts to access a non-exist quota tree
when dealing with extent_item [4198400 4096] in the corrupted filesystem.
The function btrfs_new_fs_info always allocates memory for
fs_info->quota_root regardless of whether quota_tree exists or not.
Additionally, the function btrfs_read_fs_root will directly return
fs_info->quota_root if location->objectid == BTRFS_QUOTA_TREE_OBJECTID.
This patch does the following things:
1. Do extra check and return ENOENT if quota tree does not exist in the
function btrfs_read_fs_root.
2. Free useless fs_info->quota_root in the function btrfs_setup_all_roots
to reduce confusion.
3. free_extent_buffer even if check_child_node failed in the function
walk_down_tree.

btrfs-progs: fix btrfs send & receive with -e flag
The old check here tried to ensure that empty streams are not considered valid.
The old check however, will always fail when only one run through the while(1)
loop is needed and honor_end_cmd is set. So this:
btrfs send /some/subvol | btrfs receive -e /some/
will consistently fail because -e causes honor_cmd_to be set and
btrfs_read_and_process_send_stream() to correctly return 1. So the command will
be successful but btrfs receive will error out because the send - receive
concluded in one run through the while(1) loop.
If we want to exclude empty streams we need a way to tell the difference between
btrfs_read_and_process_send_stream() returning 1 because read_buf() did not
detect any data and read_and_process_cmd() returning 1 because honor_end_cmd was
set. Without introducing too many changes the best way to me seems to have
btrfs_read_and_process_send_stream() return -ENODATA in the first case. The rest
stays the same. We can then check for -ENODATA in do_receive() and report a
proper error in this case. This should also be backwards compatible to previous
versions of btrfs receive. They will fail on empty streams because a negative
value is returned. The only thing that they will lack is a nice error message.

btrfs-progs: rework option parser to use getopt for global options
Preparatory work to support more global options. The current parser
abuses the subcommand table to understand help and version when
specified as options (--). These are now special case when processing
the global options.

btrfs-progs: fix missing __error symbol in libbtrfs.so.0
The easiest way to reproduce the error is to try to build
btrfs-progs with
$ make LDFLAGS=-Wl,--no-undefined
btrfs-list.o: In function `lookup_ino_path':
btrfs-list.c:(.text+0x7d2): undefined reference to `__error'
Noticed by Denis Descheneaux when snapper tool
stopped working after upgrade to btrfs-progs-4.10.
As soname didn't change in 4.9 -> 4.10 release
I assume it's just an object file omission
in library depends and not the API/ABI change
of the library error printing.

btrfs-progs: tests: Add SHARED_DATA_REF test image for check lowmem mode
Introduce a new image, which contains external SHARED_DATA_REF items to
trigger a lowmem mode false alert.
The image only contains external SHARED_DATA_REF and no inlined data
backref.
Before the image, we only have inlined shared data ref, which is not
enough to trigger lowmem mode false alert.

btrfs-progs: check: lowmem, fix false alert about backref lost for SHARED_DATA_REF
In check_extent_data_item(), after checking extent item of one data
extent, we search inlined data backref, then EXTENT_DATA_REF_KEY.
But we didn't search SHARED_DATA_REF, so if the backref is
SHARED_DATA_REF, then we will raise a false alert about backref lost.
Fix by also checking SHARED_DATA_REF_KEY in check_extent_data_item().
