Hi all,
this series how libxfs deals with the data, log and rt devices.
A lot of it is just tidying up cruft old code, but it then introduces
a libxfs_dev structure that describes a single device to further
simplify the code.

These variables are only initialized, and then unlink is called if they
were changed from the initial value, which can't happen. Remove the
variables and the conditional unlink calls.

Stop pretending we try to distinguish between the legacy Unix raw and
block devices nodes. Linux as the only currently support platform never
had them, but other modern Unix variants like FreeBSD also got rid of
this distinction years ago.

IRIX has the concept of a volume that has data/log/rt subvolumes (that's
where the subvolume name in Linux comes from), but in the current
Linux-only xfsprogs version trying to pretend we do anything with that
it is just utterly confusing. The volname is basically just a very
obsfucated second way to pass the data device name, so get rid of it
in the libxfs and progs internals.

No caller passes a non-zero verbose argument to xlog_is_dirty.
Remove the argument the code keyed off by it.

xlog_init currently requires a libxfs_args structure to be passed in,
and then clobbers various log-related arguments to it. There is no
good reason for that as all the required information can be calculated
without it.
Remove the x argument to xlog_init and xlog_is_dirty and the now unused
logBBstart member in struct libxfs_xinit.

The only special handling for an XFS device on a regular file is that
we skip the checks in check_open. Simplify perform those conditionally
instead of duplicating the entire sequence.

To: Carlos Maiolino; +Cc: linux-xfs
The libxfs_xinit stucture has four different ways to pass flags to
libxfs_init:
- the isreadonly argument despite it's name contains various LIBXFS_
flags that go beyond just the readonly flag
- the isdirect flag contains a single LIBXFS_ flag from the same name
- the usebuflock is an integer used as bool
- the bcache_flags member is used to pass flags directly to cache_init()
for the buffer cache
While there is good arguments for keeping the last one separate, all the
others are rather confusing. Consolidate them into a single flags member
using flags in the LIBXFS_* namespace.

All callers of libxfs_init always pass an actual sector size or zero in
the setblksize member. Remove the unreachable setblksize == 1 case.

platform_set_blocksize has a fatal argument that is currently only
used to change the printed message. Make it actually fatal similar to
other libfrog platform helpers to simplify the caller.

libxfs_init initializes the device size to 0 at the start of the function
and libxfs_open_device never sets the size to a negativ value. Remove
these checks as they are dead code.

No need to do a dev_t to fd lookup when the caller already has the fd.

A few places in xfs_repair call libxfs_device_to_fd to get the data
device fd from the data device dev_t stored in the libxfs_init
structure. Just use the file descriptor stored right there directly.

structure and remove the now unused dev_map infrastructure.

libxfs_dev structure.
