- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with

Remove write only assignments and thus fix the build after struct bufarea
TAILQ conversion (r246812).

Fix sbin/ build with a 64-bit ino_t.

Original code by: Gleb Kurtsou

Partially undo r228693, by removing NO_WFORMAT.clang in fsdb's Makefile,
and fixing the format string in sbin/fsdb/fsdbutil.c instead.

Note the remark "Work around a problem with format string warnings and
ntohs macros" was actually incorrect. The DIP(dp, di_nlink) macro
invocation actually returned an int, due to its ternary expression, even
though the di_nlink members of struct ufs1_dinode and struct ufs2_dinode
are both defined as int16_t.

Improve sparse file handling when printing the block list for an inode by

Print NULL block pointers in the direct block list. Simplify the

Get rid of major/minor number distinction.

As of FreeBSD 6, devices can only be opened through devfs. These device
nodes don't have major and minor numbers anymore. The st_rdev field in
struct stat is simply based a copy of st_ino.

Simply display device numbers as hexadecimal, using "%#jx". This is
allowed by POSIX, since it explicitly states things like the following
(example taken from ls(1)):

"If the file is a character special or block special file, the
size of the file may be replaced with implementation-defined
information associated with the device in question."

This makes the output of these commands more compact. For example, ls(1)
now uses approximately four columns less. While there, simplify the
column length calculation from ls(1) by calling snprintf() with a NULL
buffer.

Don't be afraid; if needed one can still obtain individual major/minor
numbers using stat(1).

- Merge soft-updates journaling from projects/suj/head into head. This
brings in support for an optional intent log which eliminates the need
for background fsck on unclean shutdown.

This commit adds basic support for the UFS2 filesystem. The UFS2
filesystem expands the inode to 256 bytes to make space for 64-bit
block pointers. It also adds a file-creation time field, an ability
to use jumbo blocks per inode to allow extent like pointer density,
and space for extended attributes (up to twice the filesystem block
size worth of attributes, e.g., on a 16K filesystem, there is space
for 32K of attributes). UFS2 fully supports and runs existing UFS1
filesystems. New filesystems built using newfs can be built in either
UFS1 or UFS2 format using the -O option. In this commit UFS1 is
the default format, so if you want to build UFS2 format filesystems,
you must specify -O 2. This default will be changed to UFS2 when
UFS2 proves itself to be stable. In this commit the boot code for
reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c)
as there is insufficient space in the boot block. Once the size of the
boot block is increased, this code can be defined.

Things to note: the definition of SBSIZE has changed to SBLOCKSIZE.
The header file <ufs/ufs/dinode.h> must be included before
<ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and
ufs_lbn_t.

Still TODO:
Verify that the first level bootstraps work for all the architectures.
Convert the utility ffsinfo to understand UFS2 and test growfs.
Add support for the extended attribute storage. Update soft updates
to ensure integrity of extended attribute storage. Switch the
current extended attribute interfaces to use the extended attribute
storage. Add the extent like functionality (framework is there,
but is currently never used).

Something i always wanted to see: add a function to print the list of
blocks allocated by some inode. Indirect blocks are printed
recursively, so beware :), the list could become lengthy...

Remove a not-very-useful printf(3).

Allow fsdb the ability to work with entries named with whitespace embedded.

This works by retokenizing a line with a split limit so that if the
argument count for a command is greater than the number of arguments
formed by splitting apart the line of user input, the last argument
is instead all of the remainder of the input line.

Yes, I needed this capability at one point to fix a filesystem manually,
which happened to break with a problematic space-containing directory
entry.

Respect style(9), one must not include both <sys/types.h> and
<sys/param.h> (the latter includes the former).

Correct use of .Nm. Use .Bl/.El for enumerating options. Use .An. Correct
