dhcp: 4.3.5 -> 4.3.6

1. Rebase patches to 4.3.6
- define-macro-_PATH_DHCPD_CONF-and-_PATH_DHCLIENT_CON.patch -> 0001
- dhcp-3.0.3-dhclient-dbus.patch -> 0002
- link-with-lcrypto.patch -> 0003
- fixsepbuild.patch -> 0004
- dhclient-script-drop-resolv.conf.dhclient.patch -> 0005
- 0001-site.h-enable-gentle-shutdown.patch -> 0006
- libxml2-configure-argument.patch -> 0007
- tweak-to-support-external-bind.patch -> 0008
- remove-dhclient-script-bash-dependency.patch -> 0009
- build-shared-libs.patch -> 0010
- Moved-the-call-to-isc_app_ctxstart-to-not-get-signal.patch -> 0011

2. Drop search-for-libxml2.patch
   It is overrided by libxml2-configure-argument.patch

3. Rework dhclient-script-drop-resolv.conf.dhclient.patch and
Drop replace-ifconfig-route.patch.

...
Script refresh in 2017. The aliasing code was too convoluted and needs
to go away. Migrated DHCPv4 script to ip command from iproute2 suite.
This is based on Debian script with some tweaks. ifconfig is no longer
used. Everything is done using ip tool from ip-route2.

-Subject: [PATCH] remove dhclient-script bash dependency
-
-Take the dash compatible IPv6 link-local address test from the Debian
-version of dhclient-script.
-
-Note that although "echo -e" in the OE version of dhclient-script is
-technically bash specific too, it is supported by Busybox echo when
-Busybox is configured with CONFIG_FEATURE_FANCY_ECHO enabled (which
-is the default in the OE Busybox defconfig) therefore leave as-is.

-lxml2 isn't used during the build. So, we add losely coupled
