[UWS,TAP] 3 MAJOR DEPENDENT FIX: improve significantly the parameters extraction from HTTP request in UWS (1) AND move the file-upload ability into the UWS library (2) AND the modification of parameters in UWS is now conform with the standard (3). (1) Only application/x-form-urlencoded content-type was supported. However a UWS must accept a request body containing only an XML document as a single byReference parameter. It is now done when the content-type is not known. (2) Besides multipart/form-data is now fully supported in UWS and so is still possible in TAP. (3) In the UWS standard, parameters can not be added after creation: they can just be modified. This rule is now respected in the UWS library.

[TAP,UWS] Fix a problem with the format of the error details returned by the parameter .../error/details. In TAP a VOTable document is expected, but a text/plain description was returned (default behavior in the UWS lib.). Now, a ServiceErrorWriter is used to format the error details correctly.

[UWS,TAP] Fix bug about UPLOAD: file upload (multipart/form-data) with a POST to the SetJobParam action was not possible & bug in the COS library about line termintation (it should be CRLF but some clients end lines with LF and that should have been managed by the COS lib but wasn't ; correction applied by myself but feedback from the lib developer is waited).

[UWS,TAP] Review the exceptions and logs management + Add log file rotation (with a configurable rotation frequency)
