* commands: make rvpa -relative do not return ./absolute_path
This happens on Windows when $pwd and -path is on different drive
* only return relative path inside current root
Based on standard practices, we need to have a copyright and license notice at the top of each source file. Removed existing copyrights and updated/added copyright notices for .h, .cpp, .cs, .ps1, and .psm1 files.
Updated module manifests for consistency to have Author = "PowerShell" and Company = "Microsoft Corporation". Removed multiple line breaks.
Separate PR coming to update contribution document for new source files: #6140
Manually reviewed each change.
Fix#6073
Resolving #2570.
Ignore drive paths in the check. If the input is a drive path,
then "\" is passed as the path to GetDriveQualifiedPath with drive info.
Since, the path here starts with "\", treatAsRelative is set to false
which prevents further formatting of this path.
The check is only valid for PSDrives with root path equals to UNC paths or the paths
in unix.
