Jan Vrany 5abe0f0cc7 Fix segfault when invoking -var-info-path-expression on a dynamic varobj 
Invoking -var-info-path-expression on a dynamic varobj lead either in wrong
(nonsense) result or to a segmentation fault in cplus_describe_child().
This was caused by the fact that varobj_get_path_expr() called
cplus_path_expr_of_child() ignoring the fact the parent of the variable
is dynamic. Then, cplus_describe_child() accessed the underlaying C type
members by index, causing (i) either wrong (nonsense) expression being
returned (since dynamic child may be completely arbibtrary value)
or (ii) segmentation fault (in case the index higher than number of
underlaying C type members.

This fixes the problem by checking whether a varobj is a child of a dynamic
varobj and, if so, reporting an error as described in documentation.

gdb/ChangeLog:

	* varobj.c (varobj_get_path_expr_parent): Report an error if
	parent is a dynamic varobj.

gdb/testsuite/Changelog:

	* gdb.python/py-mi-var-info-path-expression.c: New file.
	* gdb.python/py-mi-var-info-path-expression.py: New file.
	* gdb.python/py-mi-var-info-path-expression.exp: New file.
