While testing DAP, we found a situation where a compiler-generated variable caused the "variables" request to fail -- the variable in question being an apparent 67-megabyte string. It seems to me that artificial variables like this aren't interesting to DAP users, and the gdb CLI omits these as well. This patch changes DAP to omit these variables, adding a new gdb.Symbol.is_artificial attribute to make this possible.
