The three typical packages that use .config files in buildroot copy the
config file at different times in the build process:
busybox copies its .config from the post-extract hook.
linux copies its .config in the configure_cmds.
uclibc copies its .config from the post-patch hook.
Copying the .config file from the configure step is the only way to properly
support an OVERRIDE_SRCDIR that does not yet have the .config file, because
the extract and patch steps are skipped in that case.
For example, when setting a BUSYBOX_OVERRIDE_SRCDIR to a cleanly extracted
busybox tarball:
$ make busybox-dirclean busybox
rm -Rf [..]/output/build/busybox-custom
>>> busybox custom Syncing from source dir
>>> /home/tdescham/repo/contrib/busybox-1.21.1
rsync -au --exclude .svn --exclude .git --exclude .hg --exclude .bzr
--exclude CVS /home/tdescham/repo/contrib/busybox-1.21.1/
[..]/output/build/busybox-custom
>>> busybox custom Configuring
/bin/sed -i -e "/\\<CONFIG_NOMMU\\>/d"
[..]/output/build/busybox-custom/.config
/bin/sed: can't read [..]/output/build/busybox-custom/.config:
No such file or directory
make: *** [[..]/output/build/busybox-custom/.stamp_configured] Error 2
This patch modifies busybox.mk to copy the config file from the configure
step instead, as linux is doing, and fixing the described scenario.

In order to keep better track of when a feature got deprecated, and hence
when it can be removed, a new set of symbols BR2_DEPRECATED_SINCE_xxxx_xx is
introduced. These symbols are automatically selected when BR2_DEPRECATED is
selected, and thus are transparent to the user.
A deprecated feature will no longer depend on BR2_DEPRECATED directly, but
rather on the appropriate BR2_DEPRECATED_SINCE_xxxx_xx. If that symbol does
not yet exist, it has to be created in Config.in.
When removing a deprecated feature, one should also check whether this was
the last feature using the BR2_DEPRECATED_SINCE_xxxx_xx symbol, in which
case the latter can be removed from Config.in.
A followup patch will make sure the overview is added to the list of
deprecated features in the manual, so that a buildroot core developer can
easily determine which features to remove in a given development cycle.

* The PID file is not created unless the '-m' option is passed to
start-stop-daemon.
* Remove the mark '-m 0' option as it's not supported by busybox's
syslogd.
* Syslogd and Klogd forks to background by default giving as a result
that the pid stored in the PID file is not correct. Let the
background job be done by 'start-stop-daemon' by passing '-n'
(foreground) to the daemons and '-b' to start-stop-daemon. This
way the pid stored in the PID files is correct.

When udhcpc is used on multiple network devices at the same time (or a mix
of dhcp and fixed configuration), /etc/resolv.conf should contain the
union of information from all the interfaces.
Currently that's not the case. The udhcpc script simply overwrites
resolv.conf with the information from the specific interface on each dhcp
bound/renew event.
Fix it by tagging lines with the interface they came from when added,
and drop the affected lines on deconfig/renew. As /etc/resolv.conf is
often a symlink to /tmp (and rootfs might be read only), special care
has to be taken when it is updated.
Notice that I'm not really aware of any official documentation requiring
that '#' comments in /etc/resolv.conf must be supported, but atleast
glibc and uClibc do.

ifconfig up is a no-op if the device is already running, so let's just
do that unconditionally.
Systems might have multiple network devices, and perhaps run udhcpc on
another interface even when booted over nfs, so don't disable the
per-interface deconfig based on the global nfsroot= setting on the kernel
command line.
If you don't want udhcpc to mess with kernel level IP autoconfiguration
(E.G. for nfs boot), you should instead ensure udhcpc/ifup/ifplugd isn't
started for that interface.

We're currently using two different udhcpc scripts, one in the busybox
package and another in the avahi one, which calls avahi-autoipd on
dhcp failures.
The avahi one actually only does something differently from the default
if avahi-autoipd is available, so let's just always use this one instead
of the complicated logic about writing the file if not present /
overwriting it afterwards.

Busybox does partial linking of its modules before linking everything
together into the binary. Those partial links are done without the
standard libraries, but that also means -ltirpc can't be found. In
addition, this probably fails horribly with static linking (untested).
The problem is that the LDFLAGS are also used in the partial links.
So instead, use CFLAGS_busybox, which is only used for the busybox
link step. Also make sure that this is passed through the environment,
not on the command line, so the busybox Makefile can still append to
it.

Instead of making the Busybox configuration more complicated by trying
to adjust it depending on whether RPC is available or not (which gets
complicated when RPC support can be provided by libtirpc), simplify
things by letting the user enable FEATURE_NFS_MOUNT or not depending
on whether RPC support is available or not.
Our default configuration do not enable FEATURE_NFS_MOUNT, so users
will not face any build problems by default. Only if they explicitly
enable FEATURE_NFS_MOUNT will they have to make sure that the
toolchain has RPC support, or that libtirpc is enabled (support for
this added in a followup patch).
