New Revision: 52726
URL: http://svn.reactos.org/svn/reactos?rev=52726&view=rev
Log:
[RTL]: Implement RtlDosPathNameToRelativeNtPathName_U_WithStatus,
RtlDosPathNameToRelativeNtPathName_U, RtlDosPathNameToNtPathName_U_WithStatus.
[RTL]: Reimplement RtlDosPathNameToNtPathName_U to use UNICODE_STRING semantics.
[RTL]: Fix RtlGetFullPathName_Ustr.
[RTL]: RtlGetFullPathName_U remains based on the legacy non-UNICODE_STRING mechanism, but
it's too complex to attempt changing for now.
