Btrfs-progs: Do not force mixed block group creation unless '-M' option is specified
When creating small Btrfs filesystem instances (i.e. filesystem size <= 1GiB),
mkfs.btrfs fails if both sectorsize and nodesize are specified on the command
line and sectorsize != nodesize, since mixed block groups involves both data
and metadata blocks sharing the same block group. This is an incorrect behavior
when '-M' option isn't specified on the command line.
This commit makes optional the creation of mixed block groups i.e. Mixed block
groups are created only when -M option is specified on the command line.
Since we now allow small filesystem instances with sectorsize != nodesize to
be created, we can end up in the following situation,

The ENOSPC occurs during the creation of the UUID tree. This is because of
things like large metadata block size, DUP mode used for metadata and global
reservation consuming space. Also, large nodesize does not make sense on small
filesystems, hence this should not be an issue.

btrfs-progs: Introduce warning and error for common use
Current code use fprintf(stderr, "...") to output warnning and
error information.
The error message have different style, as:
# grep fprintf *.c
fprintf(stderr, "Open ctree failed\n");
fprintf(stderr, "%s: open ctree failed\n", __func__);
fprintf(stderr, "ERROR: cannot open ctree\n");
...
And sometimes, we forgot add tailed '\n', or use printf instead,
as in current code:
printf("warning, device %llu is missing\n",
This patch introduce warning() and error() as common function,
to make:
1: Each warning and error information have same format
2: Easy to search/change all error message
3: Easy to modify function's internal for debug or other requirement,
for example:
print function/linenumber in error()
dumpstack in error()
add some trace for some style of message
add support for -v, -vv, ...

Reason:
When scrub multi-device simultaneously, if some device canceled,
and some device is still running, cancel state have higher priority to

# btrfs-image -r -t0 /tmp/btrfs_image.img /dev/sda6

Reason:
The program need to create at least 1 thread for
compression/decompression. If the user specifies -t0, it overwrites the
default value of 1, then the program really creates 0 thread, and
ends up looping
Fix:
We can add a check, to make the program not to allow -t0 argument,
but there is another problem:
For example, on a node with 4 cpus:
btrfs-image -c9 -t1: 4 threads (1 means use NR_CPUS)
-c9 -t2: 2 threads
-c9 -t3: 3 threads
...
(-t1 has more threads than -t2 and -t3)
So we change to use value of 0 as "use NR_CPUS threads", then:
btrfs-image [no -t arg]: use NR_CPUS threads
-t0: use NR_CPUS threads

btrfs-progs: fix cross stripe boundary check
Commit
854437ca3c228d8ab3eb24d2efc1c21b5d56a635 ("btrfs-progs:
extent-tree: avoid allocating tree block that crosses stripe boundary")
does not work for 64k nodesize. Due to an off-by-one error, all queries
to check_crossing_stripes will return that all extents cross a stripe
and this will lead to a false ENOSPC. This crashes later
$ ./mkfs.btrfs -n 64k image
./mkfs.btrfs(btrfs_reserve_extent+0xb77)[0x417f38]
./mkfs.btrfs(btrfs_alloc_free_block+0x57)[0x417fe0]
./mkfs.btrfs(__btrfs_cow_block+0x163)[0x408eb7]
./mkfs.btrfs(btrfs_cow_block+0xd0)[0x4097c4]
./mkfs.btrfs(btrfs_search_slot+0x16f)[0x40be4d]

./mkfs.btrfs(main+0xeef)[0x434b56]
Holger Hoffstätte reports that this also fixes false positives in case
the nodesize is less than 64k. This happens when the node blocks end at
the stripe boundary.

btrfs-progs: makefile: drop u option from ar invocation
In newer distros (ubuntu 15.10, fedora rawhide) the binutils
ar uses the new D flag per default to build deterministic
binaries.
Without this patch the following warning is issued, when
building btrfs-progs:
[AR] libbtrfs.a
/usr/bin/ar: `u' modifier ignored since `D' is the default (see `U')
For libtrfs.a performance benefit of the u option can be neglected,
so drop the u option and silence the warning.
In the future one might want to explicitly add the D option anyway.
