Gabriel Krisman Bertazi e34879080d Implement catch syscall group
Implement support to add catchpoints for a group of related syscalls
using the syntax:

(gdb) catch syscall group:<group>
or
(gdb) catch syscall g:<group>

Several groups are predefined in the xml files for all architectures
supported by GDB over Linux.  They are based on the groups defined by
strace.
