6add7f75e4 Source changes to allow building a cross-debugger. Move solib.c and
solib-svr4.c to the MD makefiles because they are native files for
alpha and sparc64, but target files for amd64, i386 and ia64.

Note that kgdb(1) does not yet build as a cross-debugger due to
libkvm.

for libgdb and should do so here as well.

466bc517d1 [Sorry, forgot to commit my source changes in my previous commit.]
Document all options and general usage.

Implement the -a option to bump the annotation_level.  This improves
the Emacs gud behaviour.  You can now supply the following function

(defun gud-gdb-massage-args (file args) (cons "-a" args))

(e.g. by evaluating it from the *scratch* buffer) and get the normal
jump to the source window when browsing the stack.

We should probably eventually supply our own kgdb submode to gud.el.

8170ab332c Prepare for a subsequent import: If the first letter of the filename
changes, start on a new line. Insertion of a filename will keep the
diff limited to the block of filenames that have the same first letter
instead of creating a huge diff. While here, move remote.c after the
remote-*.c files and move tui.c after the tui-*.c files. This matches
the order of ls(1) and makes it easier to compare object files created
by a stock gdb(1) build with the list of files we have here.

This is a non-functional change only.

f52501ba8c If the argument to the -r flag starts with a ':' or a '|', don't try to
make sure it is a device.  GDB special cases these prefixes and treats
:#### as a tcp port on localhost and executes what ever follows '|'.

This allows kgdb to debug via dconschat.

7a5bf37951 Improve the usage. Without any arguments, kgdb(1) works on /dev/mem
with the currently running kernel image. Otherwise, one of -c, -n or
-r is expected for working on a particular core file (-c), working
on a saved dump (-n) or working remotely (-r). When working on a
saved dump, a kernel may be omitted.
For a remote debugging session (-r), kgdb(1) will use the specified
device.

60b992ff2f Add the beginnings of kernel debugging support. the kgdb(1) tool
is basicly a shell on top of libgdb that knows about kernel threads,
kernel modules and kvm(3). As the word "beginnings" implies, not
all of the features have been implemented yet. The tool is useful
and I'd like feedback on the taken route.

The simplest way to debug a kernel core file is:
	kgdb -n 0

This opens /var/crash/vmcore.0 with the corresponding kernel in
the object directory (kernel.debug is used if it exists).

Typical things that need to be added are:
o  Auto loading of kernel modules,
o  Handling of trapframes so that backtraces can be taken across
   them,
o  Some fancy commands to extract useful information out of a core
   file,
o  Various (probably many) other things.

o  Remove ps_getpid. We don't need it now.

306fc21ba1 Update config.h to account for the prgregset_t and psaddr_t types
that have been added to <sys/procfs.h>. This change has no effect
because the source file that would be affected is not compiled on
FreeBSD. Hence, this is for completeness only.

e7c80443b4 Don't attempt to read process context from the kernel when (the
kernel's) curproc is null.  This fixes endless recursion in
xfer_umem() for attempts to read from user addresses, in particular
for attempts to read %fs and %gs from the pcb for `info reg'.

e4e61e7b97 Simplified using new yacc rules. This is cosmetic - the old rules
worked because .ORDER prevented problems from concurrent generation
of multiple parsers (and their headers), and there were no missing
dependencies because the generated headers were not actually used.

b2198963be Removed self-inclusion-prevention ifdef. It is unnecessary now that
bsd.man.mk doesn't include ${.CURDIR}/../Makefile.inc.

Removed GDBDIR-redefinition-prevention ifdef.  It hasn't done anothing
for a long time, if ever.  The directory is defined to the same value in
each subdir and had the same value because all subdirs are at the same
level.  Keep defining it in the subdirs since that is more flexible and
no more verbose.

Prepare to inherit BINDIR by including ../Makefile.inc.
