Add support for Elf symbol tables to DDB, written from scratch by me.
...
Known to work in DDB under NetBSD/alpha.

Pass the current DDB symbol table to X_db_symbol_values().

d9f8d88a35
Fixup the software single-step code (used on architectures where there
...
is no hardware support for single-stepping):
- Fix branch prediction and delay slot computation (for the MIPS).
- Correctly deal with branch taken vs. branch not taken cases, and
self-branches.
- General cleanup, including types botches.
Partially from Mach 3, with a bunch of cleanup work by me.

Update prototypes for new function signatures. Note, the ddb_init()

signature is currently different for the DB_AOUT_SYMBOLS vs. the
DB_ELF_SYMBOLS cases. (XXX)

Use db_expr_t rather than int when reading a value from the kernel
...
address space, to avoid type-size problems.

In the db_breakpoint_t, use a db_expr_t to store the original instruction,
...
not an int.

A few small changes to make it easier to support non-a.out symbol table
...
formats in DDB:
- Reverse the sense of the symbol format #ifdef... i.e. instead of
"#ifndef DB_NO_AOUT", use "#ifdef DB_AOUT_SYMBOLS". This is pulled
in from <machine/db_machdep.h>.
- Change the signature of X_db_sym_init(). Instead of int * and char *,
it now takes void *'s for the start and end of the symbol table.
- In X_db_sym_init(), check that the pointer to the beginning of
the symbol table is aligned.
- X_db_symbol_values() now takes a "db_symtab_t *symtab" argument.

that the common case can be handled with no hassles on all machines.
fix up the various internal variables which are also exported via sysctl
(and which therefore must be 'int's) to do the right thing via a special
read/write function.

Define db_onpanic variable; if non-zero, the DDB will be entered when
...
the kernel panics. It may be initialized to 0 with the kernel option
"DDB_ONPANIC=0", and is patchable. It may be changed at run-time
from within the DDB (as a DDB variable) or via the ddb.onpanic sysctl
node.
Export all DDB built-in variables via sysctl.
