[Tracker] MAX_PATH

Consider enabling longPathAware Maximum Path Length Limitation

To enable the new long path behavior per application, two conditions must be met. A registry value must be set, and the application manifest must include the manifest longPathAware element.

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem]
"LongPathsEnabled"=dword:00000001

and

<application  xmlns="urn:schemas-microsoft-com:asm.v3">
    <windowsSettings xmlns:ws2="http://schemas.microsoft.com/SMI/2016/WindowsSettings">
        <ws2:longPathAware>true</ws2:longPathAware>
    </windowsSettings>
</application>

Updating the manifest, Windows 10, version 1607 and greater paths beyond 260 characters are available, if supported by the underlying file-system up-to 32K characters.

Notes:

• mc should support paths up to 1024 characters in length, this representing a traditional Unix limit, being a value >= _POSIX_PATH_MAX see limits for details; this internal limit can be reviewed at a later date.
• Cygwin's PATH_MAX limit is 4096, with (_XOPEN_PATH_MAX as 1024).
• Linux PATH_MAX is 4096 characters.
• NFS limit is currently 4096 characters.
