Consistently use vop_stdpathconf() for default pathconf values.

Update filesystems not currently using vop_stdpathconf() in pathconf
VOPs to use vop_stdpathconf() for any configuration variables that do
not have filesystem-specific values. vop_stdpathconf() is used for
variables that have system-wide settings as well as providing default
values for some values based on system limits. Filesystems can still
explicitly override individual settings.

Remove msdosfs -o large support.

Its purpose was to translate the values for msdosfs inode numbers,
which is calculated from the msdosfs structures describing the file,
into the range representable by 32bit ino_t. The translation acted
for filesystems larger than 128Gb, it reserved the range 0xf0000000
(FILENO_FIRST_DYN) to UINT32_MAX and remembered some arbitrary
translation of ino >= FILENO_FIRST_DYN into this range. It consumed
memory that could be only freed by unmount, and the translation was
not stable across remounts.

With ino_t type extended to 64 bit, there is no such issue and values
can be returned without compaction to 32bit. That is, for the native
environments, the translation layer is not necessary and adds
significant undeserved code complexity. For compat ABIs which use
32bit ino_t, the vfs.ino64_trunc_error sysctl provides some measures
to soften the failure mode when inode numbers truncation is not safe.

msdosfs: use mem{cpy,move,set} instead of bcopy,bzero

This somewhat simplifies use of msdosfs code in userland (for makefs),
reduces diffs with NetBSD and is standard C as of C89.

Implement VOP_FDATASYNC() for msdosfs.

Standard VOP_FSYNC() implementation just syncs data buffers, and due
to this, is the correct and efficient implementation for msdosfs or
any other filesystem which uses bufer cache trivially. Provide
globally visible wrapper vop_stdfdatasync_buf() for future consumption
by other filesystems.

msdosfs_rename: yet another unused value.

As with r295355, it seems to be left over from a cleanup
in r33548. The code is not in NetBSD either.

Thanks to bde for checking out the history.

msdosfs_rename: Unused value

Assigned value to pmp, is immediatedly overwritten before it can be used.
