retsnoop v0.8.3

Add ability to filter functions by kernel modules.

General glob format is now <name-glob> [<module-glob>], where module glob is optional. This allows to, e.g., attach to all kprobes within some module: '* [fuse]' will attach to all the functions within fuse module. Note that module glob is also a glob, so one can capture multiple modules within one glob, e.g. -a '* [kvm*]' will capture functions defined in kvm and kvm_intel modules.
