Introduce a configuration option to build a "hardened" OpenWrt with
ASLR PIE support.
Add new option PKG_ASLR_PIE to enable Address Space Layout Randomization (ASLR)
by building Position Independent Executables (PIE). This new option protects
against "return-to-text" attacks.
Busybox need a special care, link is done with ld, not gcc, leading to
unknown flags. Set BUSYBOX_DEFAULT_PIE instead and disable PKG_ASLR_PIE.
If other failing packages were found, PKG_ASLR_PIE:=0 should be added to
their Makefiles.

In case there is an external git repo specified,
it could overwrite the kernel tarball that was
downloaded from kernel.org.
The only identifier for such a file is the
KERNEL_GIT_CLONE_URI & KERNEL_GIT_REF symbols,
so if we have to download it we'll use that
information [after some sanitization]
to create a different filename for the kernel tarball.
If KERNEL_GIT_REF symbol is empty, HEAD will be used
as mentioned in the description of KERNEL_GIT_REF.

When generating per-device rootfs directories, the ./etc/opkg/ directory
is moved away prior to calling opkg install, opkg remove and rootfs_prepare.
After the opkg invocations and the rootfs_prepare macro call, the saved opkg
config directory is supposed to be moved back to its previous ./etc/opkg
location.
The mv command however can fail to properly restore the directory under
certain circumstances, e.g. when the prior opkg or files/ overlay copy
operations caused a new ./etc/opkg/ directory to be created.
In this case, the backed up directory (named target-dir-$hash.opkg) will be
moved into the preexisting ./etc/opkg/ directory instead, causing the opkg
configuration to be located in a wrong path on the final rootfs, e.g. in
/etc/opkg/target-dir-$hash.opkg/distfeeds.conf instead of
/etc/opkg/distfeeds.conf.
Solve this problem by replacing the naive "mv" command with a recursive
"cp -T" invocation which causes the backed up directory tree to get merged
with the destination directory in case it already exists.
Also perform the rootfs_prepare macro call after restoring the opkg
configuration, to allow users to override it again by using the files/
overlay mechanism.

that this feature which is implemented deep inside the linux IP stack

But a strace of iptables -t raw -I PREROUTING -p icmp -j TRACE reveals

fails as this dynamic library is not present on the system.

denial of service or possibly have unspecified other impact via crafted
system calls, a related issue to CVE-2017-8890.
CVE-2017-9242
The __ip6_append_data function in net/ipv6/ip6_output.c in the Linux kernel
through 4.11.3 is too late in checking whether an overwrite of an skb data
structure may occur, which allows local users to cause a denial of service
(system crash) via crafted system calls.

Commit 86c966a8ae caused HOST_LOADLIBES to
include -lncurses. This was added for fixing build issues on macOS.
This introduces issues on Linux when wide-character ncurses is being
used for compiling, but the non-wide-character version is linked in.
Fix this by adding the extra override for HOST_LOADLIBES only on macOS.

This commit contains the following changes
- Use local shell var where appliable
- The $(sort $$$$$$$$mods) call will have no expected effect
- Avoid EEXIST when creating symlinks in /etc/modules-boot.d/
- Avoid duplicate arguments for insert_modules() in postinst-pkg

This causes various issues in other places that assume that host
binaries are staged in STAGING_DIR_HOST.
Since all the right places use HOST_BUILD_PREFIX, override that instead.

When using external or git cloned kernels, any kind of modifications
will alter KERNELRELEASE. LEDE still tries to stage modules in
lib/modules/$(LINUX_UNAME_VERSION) and LINUX_UNAME_VERSION is based on
KERNEL_PATCHVER (indirectly) so this does not work, and we lose all
kinds of automatic modules loading.
To remedy that, just cat $(LINUX_DIR)/include/config/kernel.release
which is late enough the kernel has prepared this file, and is correctly
tracking changes done throughout the kernel.

In case we use external and/or git cloned kernels, let the kernel
determine the appropriate KERNELRELEASE. We cannot used
LINUX_UNAME_VERSION because that one gets determined at a later time,
when the kernel is already built proper.

This reverts commit 0df2c6563a since it
gets in the way of identifying properly which kernel we are running.
This is particularly important if LEDE is using external kernels/git
cloned kernels. We want to make sure we only load modules from that
specific kernel.

Refresh patches. A number of patches have landed upstream & hence are no
longer required locally:
062-[1-6]-MIPS-* series
042-0004-mtd-bcm47xxpart-fix-parsing-first-block
Reintroduced lantiq/patches-4.4/0050-MIPS-Lantiq-Fix-cascaded-IRQ-setup
as it was incorrectly included upstream thus dropped from LEDE.
As it has now been reverted upstream it needs to be included again for
LEDE.
Run tested ar71xx Archer C7 v2 and lantiq.

When running "make {config|defconfig|oldconfig}" with symlinked .config
(e.g. to env/.config) it renames symlink to .config.old, creates new
.config file, and writes the updated configuration into it.
This breaks the desired workflow when changes in the configuration can
be checked using "scripts/env diff" and commited using "scripts/env
save". Since the env/.config file is not updated.
The things become even worse when working with feeds, since feeds script
quite often silently invokes "make {oldconfig|defconfig}" and breaks the
symlink.
Fix this issue by exporting KCONFIG_OVERWRITECONFIG=1, which forces
mconf to overwrite the .config content, instead of renaming it and
creating a new file. This variable is set only if .config is a symlink,
otherwise the variable is not exported and the old behaviour is
preserved.
This change uses the same behaviour as "make menucofig", which has
already been fixed in commit 5bf98b1acc.
Also make a tiny cosmetic update to the "make menuconfig" target code
layout to make it look like other config handling targets.
