Upgrade to asm 7

I just run all tests in 3.2.x-fixes branch with this patch:

all tests pass.

background: I've prepared simultaneous release of pax-web, pax-transx, pax-jms, pax-jdbc, pax-cdi, preparing for aligned release of karaf 4.2.3.
In pax-web I've upgraded to ASM7, so now, pax-web ship/install ASM7 bundles.
Karaf itself switched to ASM7 some time ago, but the reason why (so far) CXF tests worked was that pax-web used in Karaf was installing ASM6 libraries.

CXF contains (very) wide range for ASM import: [3, 6.3) and knowing the good history of backward compatibility of ASM, I think it's worth increasing the range for ASM in CXF.
