The BusyBox watchdog application supports reset periods specified in
milliseconds. The Buildroot package will only allow an integer reset period,
which prevents the use of the required "ms" suffix. Change the watchdog period
configuration item to a string, to allow the use of the "ms" suffix.

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).

Without an mdev.conf file installed, mdev generates some /dev entries in
an incorrect or non-standard way. Some examples:
1. /dev/null has permissions 660, but it should be accessible to normal
users;
2. alsa devices get created in /dev, not /dev/snd as is more common,
and as the default value of BR2_PACKAGE_ALSA_LIB_DEVDIR suggests;
3. event<N> files are created in /dev, not /dev/input.
This mdev.conf is a selection from the examples provided in the busybox

Four methods for the creation of device files in /dev are now
proposed:
- static method uses device table as before
- devtmpfs method enables this feature in kernel
- mdev method adds mdev starting script to the file system
and selects mdev itself for installation
- udev method selects udev for installation
All dynamic methods are based on devtmpfs, so one doesn't need to care
about /dev folder.

When compiling Busybox, according to readelf -A, all object files were
properly compiled according to the select architecture (-march=armv4t
for example), but the final busybox binary could be of a different
architecture (ARMv5t even if ARMv4t was selected).
This patch changes the way we configure/compile Busybox so that our
CFLAGS aren't anymore passed through the make EXTRA_CFLAGS variable,
but through the .config CONFIG_EXTRA_CFLAGS variable. Unfortunately,
those variables don't have exactly the same semantic for the Busybox
build system.

The "project" feature was designed to allow to several projects to be
built inside the same Buildroot source tree and allowing the toolchain
and non-configurable packages to be shared between the different
projects on the same architecture. While being interesting in theory,
this feature adds a level of complexity to Buildroot, both from an
user perspective and from a developer perspective, while one of the
main Buildroot strengh is to be simple. Moreover, this feature is only
seldomly used by our users.
From a user-level perspective, this for example allows to remove the
project_build_ARCH directory, which was very confusing. The
autotools-stamps directory is also removed, since these stamps are
back at their normal location.
Description of the changes involved :
* project/, directory removed
* Makefile
- Don't include project/Makefile.in and project/project.mk anymore
- Grab a copy of the contents of project/Makefile.in at the
location it was imported, but remove the definition related to
PROJECT_BUILD_DIR. The TARGET_DIR is now in
$(BUILD_DIR)/target_dir
- Remove the creation/removal of the $(PROJECT_BUILD_DIR) and
$(PROJECT_BUILD_DIR)/autotools-stamps directories
- Don't make world depends on target-host-info. This target was
defined by project/project.mk to customize /etc/issue,
/etc/hostname and create /etc/br-version depending on the
project definitions. We can of course imagine re-adding such a
feature later.
- Replace PROJECT_BUILD_DIR by BUILD_DIR everywhere
- Remove the update, log and lognr.$(PROJECT) target, they were
specific to the project feature.
* package/Makefile.autotools.in
- Replace PROJECT_BUILD_DIR by BUILD_DIR for the location of the
configure cache
- Move the INSTALL_TARGET and HOOK_POST_INSTALL stamps to the same
directory as the other stamps (i.e, in the package directory).
* package/Makefile.in
- Replace PROJECT_BUILD_DIR by BUILD_DIR for the location of the
configure cache
* package/at/at.mk,
package/busybox/busybox.mk,
package/busybox/initramfs.mk,
package/customize/customize.mk,
package/linux-fusion/linux-fusion.mk,
package/ltp-testsuite/ltp-testsuite.mk,
package/nfs-utils/nfs-utils.mk,
target/cpio/cpioroot.mk,
target/cramfs/cramfs.mk,
target/device/Atmel/DataFlashBoot/DataflashBoot.mk,

target/linux/Makefile.in,
target/romfs/romfs.mk,
target/squashfs/squashfsroot.mk,
target/tar/tarroot.mk,
target/ubifs/ubifsroot.mk
- Replace PROJECT_BUILD_DIR by BUILD_DIR
* target/device/Config.in
- Do not include project/Config.in anymore
* target/linux/Makefile.in.advanced
- Replace PROJECT_BUILD_DIR by BUILD_DIR
- Store the stamps file in $(STAMP_DIR) instead of
$(PROJECT_BUILD_DIR)/autotools-stamps
* target/u-boot/Makefile.in
- Replace PROJECT_BUILD_DIR by BUILD_DIR
- Remove $(PROJECT) from the U-Boot target binary name
- Remove the insertion in the configuration of the project name as
the hostname
- The u-boot-autoscript target now generates
$(U_BOOT_AUTOSCRIPT).img instead of
$(U_BOOT_AUTOSCRIPT).$(PROJECT)
* toolchain/gcc/gcc-uclibc-3.x.mk
toolchain/gcc/gcc-uclibc-4.x.mk
- Move the stamps files to $(STAMP_DIR)
