d63027b668 sys/fs: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

c829016e85 Change the type of newsize argument in the smbfs_smb_setfsize() function
from int to int64.
MSDN says that SMB_SET_FILE_END_OF_FILE_INFO uses signed 64-bit integer
to specify offset, but since smbfs_smb_setfsize() has used plain int,
a value was truncated in case when offset was larger than 2G.
	https://msdn.microsoft.com/en-us/library/ff469975.aspx

In particular, now `truncate -s 10G` will work correctly on the mounted
SMB share.

14b2dc3952 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.

ce589ae2a7 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 '..'

afe097512c 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.

8d9495bb1d - 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

cd6dac7dff 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_]'.

cc518d3b67 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.

2a4ad25895 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.

11de0c59e9 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.
