Bug#1006920: please split out a libtbbmalloc2 package, both in tbb and onetbb

[Matthias Klose]

Source: tbb,onetbb
Severity: important
Tags: patch

currently libtbb2 and libtbb12 break each other, making a tbb transition hard. 
please split out a libtbbmalloc2 package, both in tbb and onetbb, such that the 
transition can happen smoothly, and the both the old and the new tbb/onetbb can 
co-exist for a while.

patch for the tbb and onetbb splitouts are attached (please check the final 
versions for the breaks/replaces).

the onetbb patch also includes the patch from upstream issue #776 to build on 
other architectures.

For Ubuntu, I'm going to rename the old libtbb-dev and libtbb-doc packages to 
libtbb2-dev and libtbb2-doc, not sure if that's something you also want to do in 
Debian, but for the next Ubuntu release we need to ship both versions, or we 
need to remove packages like numba.
