Peter Kokot c245898bfa Update and fix remaining year ranges (2019)
This patch follows previous license year ranges updates. With new
approach source code files now have simplified headers with license
information without year ranges.

-ASi Unix Extra Field:
====================
The following is the layout of the ASi extra block for Unix. The
local-header and central-header versions are identical.
(Last Revision 19960916)
Value Size Description
----- ---- -----------
(Unix3) 0x756e Short tag for this extra block type ("nu")
TSize Short total data size for this block
CRC Long CRC-32 of the remaining data
Mode Short file permissions
SizDev Long symlink'd size OR major/minor dev num
UID Short user ID
GID Short group ID
(var.) variable symbolic link filename
Mode is the standard Unix st_mode field from struct stat, containing
user/group/other permissions, setuid/setgid and symlink info, etc.
If Mode indicates that this file is a symbolic link, SizDev is the
size of the file to which the link points. Otherwise, if the file
is a device, SizDev contains the standard Unix st_rdev field from
struct stat (includes the major and minor numbers of the device).
SizDev is undefined in other cases.
If Mode indicates that the file is a symbolic link, the final field
will be the name of the file to which the link points. The file-
name length can be inferred from TSize.
[Note that TSize may incorrectly refer to the data size not counting
the CRC; i.e., it may be four bytes too small.]
