instead of a global variable. For easier initialization with dynamic number of protocols

so that we can use safely EXCEPTION_POLICY_MAX*sizeof(x)
Ticket: 5053 delay after initialization so that StringToAppProto works
Ticket: 5053
As too many cases are found when splitting tcp payload
As it is also used for HTTP/1 Remove it only for TCP and keep it for UDP.
Because some alprotos will remain static and defined as a constant, such as ALPROTO_UNKNOWN=0, or ALPROTO_FAILED. The regular already used protocols keep for now their static identifier such as ALPROTO_SNMP, but this could be made more dynamic in a later commit. ALPROTO_FAILED was used in comparison and these needed to change to use either ALPROTO_MAX or use standard function AppProtoIsValid
Ticket: 5053 The names are now dynamically registered at runtime. The AppProto alproto enum identifiers are still static for now. This is the final step before app-layer plugins.

WARNING:

Draft for unclean git history |
There was an implicit limit of 32 app-layer protocols used by probing parsers through a mask, meaning that Suricata should not support more than 32 app-layer protocols in total. This limit is relaxed to each flow not being able to run more than 32 probing parsers, meaning that for each source and destination port combination, the sum of registered probing parsers should not exceed 32, even if there are more than 32 in total.

Describe changes:
#12066 with review taken into account
This limit was luckily not a real problem for now.
The bug is setting probing parser done too soon. This may happen if the first packet does not have a full PDU...
