[RFC PATCH 00/15] PID namespace translation support

[Ákos Uzonyi]

From: Uzonyi Ákos <uzonyi.akos at gmail.com>

I will have several exams this week, so I strated working a bit earlier.
I'm sending my current status as a series of rfc patches.

I applied Eugene's old wip commit, resolved conflicts, and fixed some bugs.
After the patches marked with [fix], the translation seems to be working
(only for a few syscalls, and no caching is done yet).
These [fix] patches can be sqashed later into the original commit, but I
send them as separate patches to make review easier.

In the last commit I asked some questions in comments about Eugene's code,
please give feedback about them.
