POWHEG test fails with NAG

[Juergen Reuter]

This is the backtrace:

Runtime Error: powheg.f90, line 849: ALLOCATABLE variable is not currently allocated

[Bijan Chokoufe Nejad]

Well.. In 849 we call

       call powheg%sudakov(alr)%s%init (...)

and it gets allocated in the same subroutine (powheg_setup_sudakovs):

    allocate (powheg%sudakov (powheg%process_deps%n_alr))
    do alr = 1, powheg%process_deps%n_alr
       ...
       allocate (sudakov_simple_fsr_t :: powheg%sudakov(alr)%s)

[Juergen Reuter]

Two issues: powheg%rng was not allocated, that was the complaint from the NAG compiler. And the printout then generated NaNs? because the real components of powheg_t were not initialized. Resolved in r6629.
