Battery of NetBSD support improvements
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+).
The introduced code is subject to improve afterwards for additional features and bug fixes.
