For most time, In open_ctree_*(), we use the first superblock
(BTRFS_SUPER_INFO_OFFSET). However, for btrfs-convert, we don't,
we should pass the correct sb_bytenr to btrfs_scan_fs_devices() rather
than always use BTRFS_SUPER_INFO_OFFSET.This patch fix the following
regression:
mkfs.ext2 <dev>
btrfs-convert <dev>
warning, device 1 is missing
Check tree block failed, want=2670592, have=0
read block failed check_tree_block
Couldn't read chunk root
Segmentation fault (core dumped)

Some codes still use the cpu_to_lexx instead of the
BTRFS_SETGET_STACK_FUNCS declared in ctree.h.
Also added some BTRFS_SETGET_STACK_FUNCS for btrfs_header and
btrfs_super.

Some commands(such as btrfs-convert) access the devices again after we close
the ctree, so it is better that we don't free the devices objects when the ctree
is closed, or we need re-allocate the memory for the devices. We needn't worry
the memory leak problem, because all the memory will be freed after the taskes
die.

As we know, the file descriptor 0 is a special number, so we shouldn't
use it to initialize the file descriptor of the devices, or we might
close this special file descriptor by mistake when we close the devices.
"-1" is a better choice.

For any btrfs-$FOO executable, rename the main source file from
$FOO.c to to btrfs-$FOO.c
This makes it slightly more obvious what's building what,
and allows us to write a default rule in the Makefile for
these tools.
(also add btrfs-calc-size to the list of objects to remove
on make clean)
