These allow the generated kernel's build metadata to be defined explicitly.
This metadata is reported, eg, at boot time and in `uname -a` on running
systems. If the variables aren't configured, the current build system username
and hostname are used as normal.
The motivation for this option is to achive reproducible (bit-for-bit
identical) kernel builds of official openwrt releases.

Revision 46834 changed IPv6 support from a module to builtin. But
since the configuration of the IPv6 kernel options was left in
package/kernel/linux/modules/netsupport.mk, this means that an
empty kmod-ipv6 module was still being generated (not packaged).
This patch moves the configuration of the IPv6 kernel options to
config/Config-kernel.in to remove this last bit of the module.
Note that CONFIG_IPV6_PRIVACY was dropped (enabled by default
since Linux v3.13), so this option is no longer needed.

Memory Resource Controller no longer depends on Resource counters since
Kernel version 4.0.
3.18 is the only still supported version needing Resource counters for
MEMCG, thus declare the dependency only for that version.

This is needed by many services to function properly and as
all modern distributions got it enabled, it starts to be a
de-facto standard, i.e. user-space starts to silently depend
on it.
This also pulls in EXPORTFS, however, the kernel binary size
increases only a little.
On ARM systems comes down to 800 bytes uncompressed and about
200 bytes compressed size.
On MIPS systems it's about 1.2 kB size increase of the LZMA
compressed kernel.
v2: use menuconfig option instead of just enabling the option

This change does multiple things, all related to enable sparse usage as
a static analysis tool selectable from the OpenWrt configuration:
*add a KERNEL_SPARSE option in the config to add sparse to the kernel
build (through the C=1 option usage)
*add sparse as a new host tools. It will get selected automatically when
the above option will be enabled

Recent lxc versions are not useful if this option is not enabled. That said,
enable KERNEL_POSIX_MQUEUE by default when KERNEL_LXC_MISC is selected.

The number of Linux kernel related config options has become quite big
over the past few months, they deserve their own Config-kernel.in file.
