1. define trampolines for both exceptions with error code (automatically
pushed to stack) and those without.
2. do not repeat vectors for unused IRQ numbers: we need 48, no need to
fill in 256.
3. also pass the pointer to trap frame (on the stack) to the handler
code

1. allow unexpected cfgs in lib.rs, in this case
"no_global_oom_handling" is cause warnings [1]
2. for large code models the compiler (rust linkers) now put code and
data in `.ltext`, `.ldata`, `.lbss`, `.lrodata` instead of the
same `.text` , `.data` ... etc. We are adjusting accordingly in the
linker script.
3. unsafe assertions identified undefined behaviours, in this case a repr(C)
struct was not mared as repr(packed), therefore having an unexpected
size. The unsafe assertions was not enabled by default in debug
builds so the idt setup code with from_raw_parts_mut() has been
working on UB. Glad we can catch this....

Also renamed a few symbols to avoid confusion.
