e578b59bf6 btrfs-progs: convert strerror to implicit %m
Similar to the changes where strerror(errno) was converted, continue
with the remaining cases where the argument was stored in another
variable.

The savings in object size are about 4500 bytes:

 $ size btrfs.old btrfs.new
   text    data     bss     dec     hex filename
 805055   24248   19748  849051   cf49b btrfs.old

66d90453cd btrfs-progs: qgroups: fix misleading index check
In print_single_qgroup_table we check the loop index against
BTRFS_QGROUP_CHILD, but what we really mean is "last column."  Since
we have an enum value to indicate the last value, use that instead
of assuming that BTRFS_QGROUP_CHILD is always last.

8eb7e9d43a btrfs-progs: qgroup: swap the argument in the caller of update_qgroup_relation
The QGROUP_RELATION item is very special, it always exists in pairs
(with objectid and offset exchanged). Its objectid and offset are the
ids of a pair of parent and child qgroups, respectively. The larger one
is parent and the smaller one is child. After the following commit, the
order of the parameters is wrong and causes qgroup show to output the
wrong qgroup parent-child relationship.

f0445b8a34 btrfs-progs: qgroup: move btrfs_show_qgroups's error handler to __qgroup_search
We have to process the return value of BTRFS_IOC_TREE_SEARCH ioctl in
advance, so that we can distinguish between the two case where quota
is not enabled (ioctl return -ENOENT) and either parent qgroup or child
qgroup does not exist (update_qgroup_relation return -ENOENT). Besides
this, any error in this routine has been reported, so we don't need to
report again in cmd_qgroup_show.

Before this patch, qgroup show won't check btrfs qgroup status, so even
the INCONSISTENT flags is set, user is not aware of it.

This patch will include BTRFS_QGROUP_STATUS_ITEM in the search range and
check the flag, if there is any flag meaning the inconsistence of qgroup
data, info user.

NOTE: There is several kernel bugs from INCONSISTENT flags is always set
to RUNNING flags is not cleared until umount.
So this warning will always be here if using a newer kernel fixing these
bugs.

8ac2ddf588 Btrfs-progs: enhance btrfs qgroup show to sort qgroups
You might want to list qgroups in order of some items, such as 'qgroupid', 'rfer'
and so on, you can use '--sort'. Now you can sort the qgroups by 'qgroupid',
'rfer','excl','max_rfer' and 'max_excl'.

For example:
	If you want to list qgroups in order of 'qgroupid'.
You can use the option like that:

	btrfs qgroup show --sort=+/-qgroupid <path>
Here, '+' means the result is sorted by ascending order. '-' is by descending
order. If you don't specify either '+' nor '-', the result is sorted by
default - ascending order.

If you want to combine sort items, you do it like that:
	btrfs qgroup show  --sort=-qgroupid,+rfer,max_rfer,excl <path>

14b6c32037 Btrfs-progs: introduces '-c' option to print the ID of the child qgroups
This patch introduces '-c' option to print the ID of the child qgroups.
You may use it like:
	btrfs qgroup show -c <path>

For Example:

                qgroupid(2/0)
                 /       \
                /         \
               /           \
            qgroupid(1/0) qgroupid(1/1)
               \            /
                \          /
		 qgroupid(0/1)

If we use the command:

	btrfs qgroup show -c <path>
The result will output
	0/1 -- -- --
	1/0 -- -- 0/1
	1/1 -- -- 0/1
	2/0 -- -- 1/0,1/1

04e271786f Btrfs-progs: introduces '-p' option to print the ID of the parent qgroups
This patch introduces '-p' option to print the ID of the parent qgroups.
You may use it like:

	btrfs qgroup show -p <path>
For Example:
                qgroupid(2/0)
                /         \
               /           \

               \            /
                qgroupid(0/1)

If we use the command:

1e174d2621 Btrfs-progs: restructure show_qgroups
The current show_qgroups() just shows a little information, and it is hard to
add some functions which the users need in the future, so i restructure it, make
it easy to add new functions.

In order to improve the scalability of show_qgroups(), i add some important
structures:

	struct qgroup_lookup {
		struct rb_root root;
	}
 	/*
	*store qgroup's information
	*/
	struct btrfs_qgroup {
		struct rb_node  rb_node;
		u64 qgroupid;

		u64 generation;
		u64 rfer;
		u64 rfer_cmpr;
		u64 excl_cmpr;

		u64 flags;
		u64 max_rfer;
		u64 max_excl;
		u64 rsv_rfer;
		u64 rsv_excl;

		struct list_head qgroups;
		struct list_head members;
	}
	/*
	*glue structure to represent the relations
	*between qgroups
	*/
	struct btrfs_qgroup_list {
		struct list_head next_qgroups;
		struct list_head next_member;
		struct btrfs_qgroup *qgroup;
		struct btrfs_qgroup *member;
	}
The above 3 structures are used to manage all the information
of qgroups.

	struct {
		char *name;
		char *column_name;
		int need_print;
	} btrfs_qgroup_columns[]

We define a arrary to manage all the columns that can be
outputed, and use a member variant(->need_print) to control
the output of the relative column. Some columns are outputed
by default. But we can change it according to the requirement
of the users.

For example:
	if outputing max referenced size of qgroup is needed,the function
'btrfs_qgroup_setup_column()' will be called, and the parameter 'BTRFS_QGROUP_MAX_RFER'
(extend in the future) will be passsed to the function. After the function is done,
when showing qgroups, max referenced size of qgroup will be output.

66253a8183 btrfs-progs: fix qgroup realloc inheritance
qgroup.c:82:23: warning: memcpy with byte count of 0
qgroup.c:83:23: warning: memcpy with byte count of 0

The inheritance wasn't copying qgroups[] because a confused sizeof()
gave 0 byte memcpy()s.  It's been like this for the year since it was
merged, so I guess this isn't a very important thing to do :).

In files copied from the kernel, mark many functions as static,
and remove any resulting dead code.

Some functions are left unmarked if they aren't static in the
kernel tree.

9886166880 Btrfs-progs: clean up reduplicate parse_qgroupid() and replace atoi with strtoull
1. parse_qgroupid() is implemented twice, clean up the reduplicate code.
2. atoi() can not detect errors, so use strtoull() instead of it.
