Add new error message wrapping APIs

Add four new public APIs for wrapping error messages:
krb5_prepend_error_message, krb5_vprepend_error_message,
krb5_wrap_error_message, and krb5_vwrap_error_message.  The first two
functions are from Heimdal and allow a prefix to be added to the
existing message for a code.  The latter two functions also allow the
code to be changed.

[ghudson at mit.edu: rename krb5_prepend_error_message2 to
krb5_wrap_error_message; clarify doxygen comments and put them in the
proper form; implement krb5_prepend_error_message in terms of
krb5_wrap_error_message; fix leak and null context handling in
krb5_wrap_error_message; rewrite commit message]
