MFC r264494:
Use SMB_QUERY_FS_SIZE_INFO request to populate statfs structure.
When server doesn't support this request, try to use SMB_INFO_ALLOCATION.
And use SMB_COM_QUERY_INFORMATION_DISK request as fallback.

MFC r264600:
Remove redundant unlock.

This code was removed from the opensolaris and darwin's
netsmb implementations, in DfBSD it also has been disabled.

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

- Fix double frees/user after free.
- Allocate using smb_rq_alloc() instead of inlining it.

smbfs_lookup() in the DOTDOT case operates on dvp->n_parent without
proper locking. This doesn't prevent in any case reclaim of the vnode.
Avoid this not going over-the-wire in this case and relying on subsequent
smbfs_getattr() call to restore consistency.
While I'm here, change a couple of SMBVDEBUG() in MPASS().
sbmfs_smb_lookup() doesn't and shouldn't know about '.' and '..'

Fix panic due to page faults while in kernel mode, under conditions of
VM pressure. The reason is that in some codepaths pointers to stack
variables were passed from one thread to another.

- Remove the references to the deprecated zalloc kernel interface
- Use M_ZERO flag in malloc() rather than bzero()
- malloc() with M_NOWAIT can't return NULL so there's no need to check

Add unicode support to msdosfs and smbfs; original pathes from imura,

Tested by me in production for several days at work.

Make a comment more accurate.

This comment refers to CAP_NT_SMBS, which does not exist; it should refer to SMB_CAP_NT_SMBS.
Fixing this comment makes it easier for people interested in Capsicum to grep around for
capability rights, whose identifiers are of the form 'CAP_[A-Z_]'.

Fix interaction with Windows 2000/XP based servers:

If the complete reply on the TRANS2_FIND_FIRST2 request fits exactly
into one responce packet, then next call to TRANS2_FIND_NEXT2 will return
zero entries and server will close current transaction. To avoid
subsequent errors we should not perform FIND_CLOSE2 request.

Convert to nmount. Add omount compat.

Unpropagate the sm_args function into the runtime part.

Fix an inverted test for NOPEN in the unused function smb_smb_flush().

Send the close request to the SMB server in smbfs_inactive(), instead of
smbfs_close(). This fixes paging to and from mmap()'d regions of smbfs
files after the descriptor has been closed, and makes thttpd, GNU ld,
and perhaps more things work that depend on being able to do this.

Store a reference to the parent directory's vnode in struct smbnode,
not to the parent's smbnode, which may be freed during the lifetime
of the child if the mount is forcibly unmounted. umount -f should now
work properly (ie. not panic) on smbfs mounts.

Cast a pointer to a uintptr_t to quiet a warning.

Implement additional SMB calls to allow proper update of file size as some
file servers fail to do it in the right way.
