Ancient Browser Experience

While trying to match 68k bsdsocket calls to x86 bsdsocket calls, I realized, how "old" our bsdsocket.library seems to be. Nearly every bsdsocket.library function is marked with texts like "THIS IS A DEPRECATED METHOD OF GETTING HOST NAMES" in modern man pages..
Nevertheless, there is progress :).


Aweb can be started in AmigaOS 3.1 running in j-uae v1.3 and load at least parts of a webpage. The real challenging parts of m68k <-> x86 communications seems to be fixed. 

Every call from an m68k application has to take the following route (aweb example):


aweb -> 
m68k/bsdsocket.library ->
j-uae TRAP handler -> 
x86/j-uae-bsdsocket-task -> 
x86/bsdsocket.library
 

For every open of a 68k bsdsocket.library (every open creates a new SocketBase), I start a new x86 process, which then himself opens a x86 bsdsocket.library. Every 68k bsdsocket.library function call needs to be serialized through the j-uae trap handler and then routed to the according x86 process. 

The communication between the x86 native trap handler and the x86/j-uae-bsdsocket-tasks is done with simple Put/GetMsg calls, just to get an individual task context for each library base.
