Clean up various use of escape/unescape functions for URL generation (#6334)
* Use PathUnescape instead of QueryUnescape when working with branch names Currently branch names with a '+' fail in certain situations because QueryUnescape replaces the + character with a blank space. Using PathUnescape should be better since it is defined as: // PathUnescape is identical to QueryUnescape except that it does not // unescape '+' to ' ' (space). Fixes #6333 * Change error to match new function name * Add new util function PathEscapeSegments This function simply runs PathEscape on each segment of a path without touching the forward slash itself. We want to use this instead of PathEscape/QueryEscape in most cases because a forward slash is a valid name for a branch etc... and we don't want that escaped in a URL. Putting this in new file url.go and also moving a couple similar functions into that file as well. * Use EscapePathSegments where appropriate Replace various uses of EscapePath/EscapeQuery with new EscapePathSegments. Also remove uncessary uses of various escape/unescape functions when the text had already been escaped or was not escaped. * Reformat comment to make drone build happy * Remove no longer used url library * Requested code changestokarchuk/v1.17
