[RFA]: error_silent for use in pending breakpoint support

To properly support pending breakpoints, gdb needs to be able to 
suppress the "not found" messages at will, but it also needs to 
sometimes issue these messages and determine the cause of the error was 
a "not found" event.

To handle the problem, I propose two new useful functions in utils.c.  
The first is error_silent() which works just like error(), only it does 
not issue the error message.  Like error(), it stores the error message 
in gdb_lasterr.  This leads to the other new function: 
error_last_output() which is used to output the last error message.

This allows the pending breakpoint support to issue the error message 
when the user is doing the initial break command and to suppress it when 
shared libraries are being loaded or a pending breakpoint is reenabled.

Ok to commit?

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