Calling a build ##.##-CURRENT might mislead users into thinking that this
build is the most current release of a branch.

Signed-off-by: Jo-Philipp Wich <jo@mein.io>

Move the revision info to the VERSION_CODE variable and default VERSION_NUMBER
to CURRENT for master branch builds.

Also introduce a new menuconfig option CONFIG_VERSION_CODE which allows users
to override the revision value put into VERSION_CODE and adjust the template
files used by the base-files package to accomodate for the changed semantics.

While we're at it, also adjust the various URLs to match the current web site.

After this commit, the relevent files will look like the examples given below:

    # cat /etc/openwrt_version
    r2398+1

    # cat /etc/openwrt_release
    DISTRIB_ID='LEDE'
    DISTRIB_RELEASE='CURRENT'

    DISTRIB_CODENAME='reboot'
    DISTRIB_TARGET='x86/64'
    DISTRIB_DESCRIPTION='LEDE Reboot CURRENT r2398+1'
    DISTRIB_TAINTS='no-all override'

When building packages within the SDK, there is no Git revision history
available so prepopulate SOURCE_DATE_EPOCH in version.mk, similar to
how we handle REVISION already.

/etc/os-release is the standard distribution release information
file, therefore add it (and image configuration options for
fields not previously present in LEDE).  Once it is deemed
reasonable the non-standard openwrt_release, openwrt_version,
and device_info files could be removed (that is with this patch
we consider them deprecated in favour of the standard file).

Centralize setting all version information in include/version.mk
* Set RELEASE env variable in include/version.mk instead of toplevel.mk.
  Stop exporting the variable.
* Remove hardcoded release name from /etc/banner
