Stop requiring that .strtab has long alignment.

2020-05-26T21:35:43Z

When ddb loads symbols, the .strtab contains char strings and doesn't need long alignment. Our bootloader provides long alignment, but I started loading symbols on powerpc64 without our bootloader. ok mpi@ guenther@ kettenis@

Separate the stack trace saving interface from ddb. The saving does not

require the debugger on most architectures, and the separation makes the code easier to use from other subsystems. The function definitions are still conditional to DDB. However, that should not matter for now. OK deraadt@, mpi@

If the kernel panics due to SMEP or SMAP, print correct stack trace

and pass information to ddb. This helps to debug kernel NULL pointer function calls. input guenther@; OK kettenis@

Default to 0 arguments if no symbol has been found in the CTF section.

Symbols not present in the CTF data are generally assembly routines which have either no argument or do not follow the ABI that the various MD stack unwinders understand. This makes ddb(4) trace simpler to understand. ok jasper@
