[patch, libgfortran] PR25139 and PR25510

[Jerry DeLisle]

:ADDPATCH fortran:

This patch includes the "simple" patch for 25139 and also adds two new error 
types which are then used in list_read.c and transfer.c.  A test case for 25139 
is provided.  I do not have a test case for the new error types. These errors 
would likely only occur during testing of new code if we screw up.

I will rename backspace.f in testsuite to backspace_1.f at the proper time.

NIST tested, regression tested.  OK for 4.2 and then 4.1 a bit later?

Regards,

Jerry
