netfilter: nf_conntrack: refactor l4proto support for netns
Move the code that register/unregister l4proto to the module_init/exit context.
Given that we have to modify some interfaces to accomodate these changes, it is a good time to use shorter function names for this using the nf_ct_* prefix instead of nf_conntrack_*, that is:
nf_ct_l4proto_register nf_ct_l4proto_pernet_register nf_ct_l4proto_unregister nf_ct_l4proto_pernet_unregister
We same many line breaks with it.

net: Don't export sysctls to unprivileged users
In preparation for supporting the creation of network namespaces by unprivileged users, modify all of the per net sysctl exports and refuse to allow them to unprivileged users.
This makes it safe for unprivileged users in general to access per net sysctls, and allows sysctls to be exported to unprivileged users on an individual basis as they are deemed safe.

netfilter: nf_conntrack: prepare namespace support for l4 protocol trackers
This patch prepares the namespace support for layer 4 protocol trackers. Basically, this modifies the following interfaces:
* nf_ct_[un]register_sysctl * nf_conntrack_l4proto_[un]register
to include the namespace parameter. We still use init_net in this patch to prepare the ground for follow-up patches for each layer 4 protocol tracker.
We add a new net_id field to struct nf_conntrack_l4proto that is used to store the pernet_operations id for each layer 4 protocol tracker.
Note that AF_INET6's protocols do not need to do sysctl compat. Thus, we only register compat sysctl when l4proto.l3proto != AF_INET6.

This patch defines a new interface for l4 protocol trackers:

that is used to return the array of unsigned int that contains the timeouts that will be applied for this flow. This is passed to the l4proto->new(...) and l4proto->packet(...) functions to specify the timeout policy.
This interface allows per-net global timeout configuration (although only DCCP supports this by now) and it will allow custom custom timeout configuration by means of follow-up patches.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies.
percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion.
http://userweb.kernel.org/~tj/misc/slabh-sweep.py
The script does the followings.
* Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h.
* When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order.
* If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file.
The conversion was done in the following steps.
1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files.
2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files.
3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind.
4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually.
5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary.
6. percpu.h was updated not to include slab.h.
7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq).
* x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig
8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point.
Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.
