* commit 'fff00eee':
  Tests for S3 group dispatch, match.call, syscall
  Fix S3 dispatches according to the first non-missing argument
  Fix: default argument na.rm for Summary methods
  Fix: match.call() works properly with S3 dispatch

* commit '3a3a55e4':
  fix dimnames bug; move code from RVector to vector extract code

Fix of arguments matching for S3 with respect to default arguments
reveals that Summary methods were not receiving na.rm argument,
which has default value in the dispatch methods, e.g.
max(...,na.rm=FALSE) calls max.myclass(...,na.rm), if invoked as max(value),
the na.rm parameter in max.myclass is missing.

The solution is semi-generic: FunctionDispatch.execute gets another parameter
that should carry the default arguments from S3 group dispatch the method
dispatched to. This parameter can, however, be only null or RArguments.SUMMARY_GROUP_DEFAULT_VALUE_NA_RM.
This parameter is passed to ArgumentMatcher, which does identity check on the
only possible value for the time being and performs the matching accordingly.

Involves fixing of matching arguments for UseMethod/NextMethod -- arguments
with default values, for which the caller does not provide any value,
are ignored and not passed to the S3 generic, not even as varargs.

ArgumentMatcher puts a special placeholder into the signature for
arguments that were 'unmatched' (with default value, but not provided).
CallMatcherNode then removes such args from the arguments array and
from the signature and continues as normal.
