Add error codes, update error codes documentation, reduce changes in errors.c by ordering error codes

* lasso/errors.h lasso/errors.c
- add to report non schema conforming XML trees, decyrption
failure due to missing private keys and invalid signatures on assertions.
- update documentation of LASSO_SERVER_ERROR_PROVIDER_NOT_FOUND,
LASSO_SERVER_ERROR_ADD_PROVIDER_PROTOCOL_MISMATCH,

* lasso/build_strerror.py:
before outputting switch cases, order error codes
name lexically in order to reduce change lines
when adding new error codes.
