vppinfra: allocate bihash virtual space on demand
Reduces the vpp image virtual size by multiple gigabytes Add a "show bihash" command which displays configured and current virtual space in use by bihash tables. Modify the .py test framework to call "show bihash" on test tear-down Type: refactor Change-Id: Ifc1b7e2c43d29bbef645f6802fa29ff8ef09940c Signed-off-by: Dave Barach <dave@barachs.net>
