This function is public so that custom ODB backends and the like can
relay an error message through libgit2. Most regular users of libgit2
will never need to call this function -- actually, calling it in most
circumstances (for example, calling from within a callback function)
will just end up having the value overwritten by libgit2 internals.
This error message is stored in thread-local storage and only applies
to the particular thread that this libgit2 call is made from.
@param error_class One of the git_error_t enum above describing the
general subsystem that is responsible for the error.
@param string_ The formatted error message to keep
@return 0 on success or -1 on failure
Set the error message string for this thread.
