This commit I made several changes:
- Use structure instead of simple bson.M(interface{}). bson.M has
some shortcomings: 1) It makes the database in chaos and hard to
read, but this's not important; 2) Some entrys may has more or
less content than others, which makes it hard to decode and filt.
So I design new data structure to encode and decode. Hopes that
there's no bugs.
- Fix the way to calculate file path. The original method is to add
all the PATH entries together, that's totally wrong! PATH entry
has several types, as it shows in "objtype". I can't find it in
the kernel src code, so what i know is just "PARENT" means the dir
the file is in, while the filename itself has the path, so we
whould ignore all "PARENT"s. When the src code is found, we should
check it again.
- Fix bugs in updating. The update function of mongodb is set to
required to has a '$' such as 'set'/'push', so when we update a
whole doc, we should use replace but not update function. And,
we should never ignore the error infomation it gives us.
Hope that there's no more bugs for this Big Change.
Now its' time to write filter as well as viewer. Best wishes with
NO BUGS!

For some reasons, kernel-connector can catch exec event, but it
doesn't tell me about what the process exec and what're its args.
So we should use audit to collect these infomations, and complete
in the database.
However, there's different delays between connector and audit,
although they both use netlink socket, as a result of which, exec
may comes before fork. we deal with it the same way. But, there's
also exec event lost, may because of the check for ppid in exec
event, but it's necessary, and if is deleted, too much irrelavent
infomation would flood into database, i've tried. So make it there,
just go forward.
Besides, what's newly discovered is that pthread_create also use
clone syscall, but if pid 1 has a thread 2, the exec info will say
that pid 2 execs. So i shouldn't ignore connector msg that childPid
ne childTgid.
This is my first attempt to use git-submodule function in my own pro-
ject, also golang local package. Congratulations!
Now, fight to fix about file operations. Hope that there wouldn't
be too many fucking bugs.
