New easyrsa will look for missing vars and x509-types where easyrsa
is located (following symlink). /usr/bin/easyrsa is now a link
to /usr/lib/easyrsa/easyrsa and /usr/lib/easyrsa/{vars,x509-types} a
link to /etc/easyrsa/{vars,x509-types}. This keeps the same previous
OpenWrt easyrsa behavior which tries to use $PWD/pki and
/etc/easyrsa/{vars,x509-types}, but without patching it.
Easyrsa can also use env vars to set pki root path (instead of
/usr/lib/easyrsa), pki path (instead of $PWD/pki) and vars path.
Those variables are commented in /etc/profile.d/50-openvpn-easy-rsa.sh
as an example of how to make easyrsa run independent of $PWD. That
scriptlet also sets $EASYRSA_TEMP_DIR from $EASYRSA_PKI/tmp to /tmp
in order to avoid writing to persistent media (normally flash). However,
as a profile scriptlet, it will only be used after session is restarted.
The "build" tgz was replaced by the "source" tar. "build" version has a
different file structure, making any patch backports too complex.
I'm also putting myself as maintainer.
Closesopenwrt/openwrt#2926, since it moved to openwrt/packages.
