[Swan-dev] use @IPSECBASEVERSION@ when going to 4.x dev cycle.

[Antony Antony]

I am glad to see 4.0 is out.
Looking at the commit that bump to 4.0 I notice a drift.

Use of IPSECBASEVERSION as oppesed to @IPSECBASEVERSION@ are popping up

When changing to 4.x cycle would be a good time to drift towards  
@IPSECBASEVERSION@ again.

Here is a previous discusions and concencus for @IPSECBASEVERSION@
