Add TP for check assurance level presence and value
Fix references

Add TP to check correct signer type for authorization ticket

check that AA signed by root or other AA

Adapt TP to check the content of the generation_time instead of waiting for a timeout.

we have decided to remove AID checks  from all TPS where it isn't a goal of TP. It will be implicitly tested in TTCN anyway.

fixed English

Check start < end instead of start <= end
TP is modified to support all 3 types of time validity restrictions for future use of other certificates.

2. Check generation time over all possible time validity restriction forms
3. Clean up TPs removing {}
fix #0007298 

Keep duplicated TPs for 3 section to follow the standard
#0007273

length restriction added

Summary: AA --> AT

TP reformulated

TP_SEC_ITSS_SND_CAM_10_01_BV
TP_SEC_ITSS_SND_DENM_04_01_BV
TP_SEC_ITSS_SND_GENMSG_04_01_BV

Actually, as there is no differences in generation time verification I just combined all these TPs to one (TP_SEC_ITSS_SND_GENMSG_04_01_BV) and removed ITS_AID check

strange sentence removed from TP
