e54f006e8c opensnoop: Monitor both sys_exit_open and sys_exit_openat. 
In glibc 2.26 and above the open() wrapper function uses the sys_openat syscall
instead of sys_open(), which (for code linked with libc) breaks opensnoop unless
openat is monitored.

f801597351 Fixes #81 - When the kernel informs us of LOST EVENTS, clear lastfile 
Correlating two lines seperated by a gulf of lost events results in
spurious output, for example a open that was attempted on a non-existing
file, but which seems to have resulted in a valid returncode.

7579fea0dd tpoint: Make -p switch respect all process' threads 
This makes -p pass all the process thread ids to the ftrace
common_pid filters. Previously, only the main thread would be
traced for each process. The -L switch now works for only a
single, specified thread.

b41b1cd3b8 funcslower: Make -p switch respect all the process' threads 
The -p switch used to set the `set_ftrace_pid` file, which is really
a thread id from the user's perspective. As a result, only the main
thread would be traced. Fix by enumerating the thread ids from /proc/
$pid/task and putting them all in `set_ftrace_pid` when asked.

The only thing missing is the capability of adding filters, example:

56edb4e321 syscount: Fix for perf list and perf script. 
perf list adds the header 'List of ..' which requires to be filtered,
otherwise follow up commands fail.

perf script has had its option for fields changed from '-f' to '-F' in
recent perf. Hence, using longer option for compatibility.
