v2:
1) parser updated to properly parse strings like this: "11:%x 1:%d"

Protobuf generic show function now accept a string with pretty specificators.
The string have to look like below (an example):

"0:%d 3:%u"

where numbers with colon specifies field number (the same number as in
proto-file) and "%[a-zA-Z]" specifies output format.
If pretty specificator for specified for a field, then it will be used for
output instead of generic hexidecimal view.

Since we use some kernel tricks for CMSG_FIRSTHDR
some compilers (in particular gcc version 4.4.5
20110214 (Red Hat 4.4.5-6)) do complain about strict
aliasing.

Thus pass -fno-strict-aliasing to be on the same
coast as kernel is.

When we fork a pidns init there's no need in specifying its pid,
as it will be autogenerated to 1. Clean the code not to mess with
the last_pid sysctl at all in that case, rather than just omitting
the write into it.

When we restore a pid namespace the root task will get some unknown pid

this pid out one can use this option -- it will make the pid obtained by
