Virtual ports on multiple incoming connections

[mathisrichter]

Objective of issue: Feature request to support virtual ports on multiple incoming connections to a Port.

Lava version:

• 0.4.0 (feature release)
• 0.3.1 (bug fixes)
• 0.3.0 (current version)
• 0.2.0
• 0.1.2

I'm submitting a ...

• bug report
• feature request
• documentation request

Current behavior:

• Lava currently only supports virtual ports on a single connection to a Port.

Expected behavior:

• Virtual ports need to be supported on any arbitrary network topology.

Related code:

# this kind of topology is currently not supported
src1 = Proc()
src2 = Proc()
dst = Proc()
src1.out_port.transpose().connect(dst.in_port)
src2.out_port.transpose().connect(dst.in_port)
