[PATCH] reset nfacct counters

[Alexey Perevalov <a.perevalov@samsung.com>]

Hello Pablo,
I used you guidance on flags usage for separate counters reset.
If no flags were specified we'll have old behaviour. I wanted to remove
NFNL_MSG_ACCT_GET_CTRZERO and use combination of (NFACCT_F_RESET_COUNTERS |
NFACCT_F_RESET_QUOTAS). But in this case I didn't find how to solve backward
compatibility issue.

You proposed to allocate memory for filter entity to use it with
netlink_dump_control, but netlink_dump_start is synchronous all the way,
and stack variable could be used there. But I could be wrong here and
there is a use case where netlink_dump_control's callback is calling from
another thread.

Due nfnetlink_acct header was modified, I think I need to send additional patches
for nfacct and libnetfilter_acct git reposotories. I saw such practice,
nfnetlink_acct.h duplicates in these repositories.

This patch was made for git://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git
repository, on top of 633594bb2d3890711a887897f2003f41735f0dfa commit.

Do you need a patch for nfacct command line tool to support following behaviour:
nfacct list reset [counter|quota] ?
