History
Philippe Waroquiers c801f8f138 fix leak in gdb_environ 
valgrind reports a leak when assigning a gdb_environ to another gdb_environ.
The memory allocated for the target gdb_environ env variables is not released.
The gdb_environ selftest reproduces the leak (see below).
Fix the leak by clearing the target gdb_environ before std::move-ing the
members.

Tested natively and re-running all tests under valgrind.
