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
Make changes to not expose the aliases "gin", "gsv", "sasv" and "spsv" in Unix platforms.
Also refactored aliases related tests and added new tests covering the complete list of built-in aliases/cmdlets.
* [build.psm1] - mc.exe input file needs quotes
For filenames that have spaces or paths to that file that have spaces, the input filename needs to have quotes around it.
* Quoted more paths so tests run from directories with spaces
Found a few locations where paths weren't qutoed or escaped with '& ...' that are needed to get tests to run from build directories with spaces in them.
This restructuring moves tests to a directory name which matches the module
in which the cmdlet resides which should improve the discoverability of a
specific test.
For tests which are not about cmdlets in a module, new directories have been
created to make those tests easier to find as well
