PR #1739 added code to leak routes between (default VRF) VPN safi and unicast RIBs in any VRF. That set of changes included temporary CLI including vpn-policy blocks to specify RD/RT/label/&c. After considerable discussion, we arrived at a consensus CLI shown below.
The code of this PR implements the vpn-specific parts of this syntax:
router bgp <as> [vrf <FOO>]
address-family <afi> unicast
rd (vpn|evpn) export (AS:NN | IP:nn)
label (vpn|evpn) export (0..1048575)
rt (vpn|evpn) (import|export|both) RTLIST...
nexthop vpn (import|export) (A.B.C.D | X:X::X:X)
route-map (vpn|evpn|vrf NAME) (import|export) MAP
[no] import|export [vpn|evpn|evpn8]
[no] import|export vrf NAME
User documentation of the vpn-specific parts of the above syntax is in PR #1937

Building alpine packages in a "standard" distro can be
complicated due to the limited scope of the distro (embedded
and small docker images). Building in a VM is one possibility,
but docker support for alpine is very good (default docker images
come in alpine due to the very small size).
Here, we want to package up the current git repo into apk packages
that can be easily installed in alpine linux using the apk tool.
This support is not intended to package released versions of
apk packages, that, if it comes to be, should be done here:
git://git.alpinelinux.org/aports
We're content here to build packages that can be used by developers
to try out frr in docker and other alpine environments.
This is a very minimal environment, we don't support importing
keys (so, installing the packages with apk requires the
--allow-untrusted option). In addition, we can't use the
git commit id in hex as version tag, as alpine doesn't support hex
digits in the version string. So, we need to convert the git hash
to decimal before tagging the package with the extra version.
This is yucky, but I can't think of another way to get a
unique version per package. The alpine way (using a numeric date),
only works for released packages, not for dev packages.

When building the rpms, we can use a chroot (in my case docker) to
ensure that the BuildRequires are complete. This test failed with
errors like:
checking for CARES... no
configure: error: trying to build nhrpd, but libcares not found. install c-ares and its -dev headers.
error: Bad exit status from /var/tmp/rpm-tmp.FewvLf (%build)
This is due to a couple missing BuildRequires in the spec file. Here, we
add those in for all RPM builds.
Testing done:
Ran a docker build on CentOS7 which succeeded. Loaded the modules onto
CentOS6 to make sure they were at least valid there, that succeeded.

This should be ok because the range of input is a very limited

If a user enters a route inside a non kernel existant vrf:

Currently if I try to use a nexthop-vrf that has

Add code to zebra so that if we fail to find the nexthop-vrf
we auto create it, instead of failing the install.

When we receive an arbitrary table over the netlink bus
save it for later perusal and sweep any routes that
we may have created from an earlier run.
The current redistribute code is limited to
ZEBRA_KERNEL_TABLE_MAX. I left this alone for the
moment because I believe it needs to be converted
to a RB tree instead of a flat array. Which is more
work for the future. Additionally this proposed
change might necessitate some cli changes or rethinks.
