Browse Source 
Summary:
Include initial support for:
 - single step mode (PT_STEP)
 - single step trap handling (TRAP_TRACE)
 - exec() trap (TRAP_EXEC)
 - add placeholder interfaces for FPR
 - initial code for NetBSD core(5) files
 - minor tweaks

While there improve style of altered elf-core/ files.

This code raises the number of passing tests on NetBSD to around 50% (600+/1200+).
