* linespec.c (decode_variable, symtab_from_filename):  Call
        error_silent with error message instead of throwing an exception
        directly.
        * defs.h (error_silent, error_output_message): Add prototypes.
        (catch_exceptions_with_msg): Ditto.
        * utils.c (error_silent, error_output_message): New functions.
        * top.c (catch_exceptions_with_msg): New function.

new cleanup_chain is established. The old values are restored
before catch_exceptions() returns.
The variant catch_exceptions_with_msg() is the same as
