- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Add a /S mode to DDB "ex" command, which interprets and prints the
value at the requested address as a symbol. For example, "ex /S
aio_swake" prints the name of the function currently registered in
via aio_swake hook.

The change as committed differs slightly from the patch in the PR,
as I force the size of the retrieved value (and the automatic
address increment) to be sizeof(void *). This seems to provide
the most useful auto-increment behavior, and defaults using the
default size (4), which is not sizeof(void *) on 64-bit platforms.

Make the examine command honor db_pager_quit so you can use 'q' or 'x'
at the pager prompt to abort an examine command that spans multiple pages.

Fixed formatting of printing of command tables. WIth the default max
output width of 79, only 6 columns of width 12 each fit, but 7 columns
were printed.

The fix is to pass the width of the next output to db_end_line() and
not assume there that this width is always 1.

Related unfixed bugs:
- 1 character is wasted for a space after the last column
- suppression of trailing spaces used to limit the misformatting, but
seems to have been lost
- in db_examine(), the width of the next output is not know and is
still assumed to be 1.

Start each of the license/copyright comments with /*-

Use __FBSDID().

- Rename the DDB specific %z printf format to %y.
- Make DDB use %y instead of %z.
- Teach GCC about %y.
- Implement support for the C99 %z format modifier.

Don't assume that pointers are 4 bytes or sizeof(int) in size. This fixes
the indirection operator ('*') and address examination ('x/a') on
big-endian platoforms for which the above is not true, as well as on
little-endian platforms if the cut-off bits are not 0.

Remove __P.

Quiet warnings on Alpha. (db_expr_t is a long on alpha, int on x86)

Restored used include of <sys/systm.h>. -Wmissing-prototypes doesn't work
for builtin functions.

Use not-so-new printf formats %r and/or %z instead of %n and/or %+x.

Fixed db_printf format errors (except for ones using broken extensions
(nonstandard %n and '+' with %x), and ones not found by -Wformat on
386's (some db_expr_t's are still printed as ints).

I decided not to change the arg type for %n from [unsigned] int to
register_t, since about half of the uses of %n are to print plain
ints and casting to [unsigned] long for %n is no harder than for %x.

Support 'g' format for printing 8 byte values.

Use %+11ln for printing in r format to make it work for 64bit registers.

Add initial support for the FreeBSD/alpha kernel. This is very much a
work in progress and has never booted a real machine. Initial
development and testing was done using SimOS (see
http://simos.stanford.edu for details). On the SimOS simulator, this
port successfully reaches single-user mode and has been tested with
loads as high as one copy of /bin/ls :-).

Make DDB work again after I broke it :-(.

This commit fixes various 64bit portability problems required for
FreeBSD/alpha. The most significant item is to change the command
argument to ioctl functions from int to u_long. This change brings us
inline with various other BSD versions. Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

Fixed gratuitous ANSIisms.

Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Fixed the one remaining %r.

Get rid of two and a half printf in the kernel.
Add more features to the one remaining to handle the job:
+ signed quantity.
# alternate format
- left padding
* read width as next arg.
n numeric in (argument specified) default radix.

Fix the DDB debugger to use these.
Use vprintf in debug routine in pcvt.

The warnings from gcc may become more wrong and intolerable because
of this.

Warning: I have not checked the entire source for unsupported or
changed constructs, but generally belive that there are only a few.

Reduced and cleaned up #includes.

Untangled the vm.h include file spaghetti.

Staticized and '#ifdef notused' stuff we don't use.

Completed function declarations and/or added prototypes and/or #includes
to get the prototypes.

Changed some `int's to `boolean_t's. boolean_t's are ints so they are
hard to distinguish from ints.

Converted function headers to old-style. ddb is written in K&R1 C
except where we broke it.

Remove trailing whitespace.

Print the address associated with an examine. Changed db_maxoff to
something more reasonable (64k). Suggested by Gordon Ross about a
year ago.

Fix up some sloppy coding practices:

- Delete redundant declarations.
- Add -Wredundant-declarations to Makefile.i386 so they don't come back.
- Delete sloppy COMMON-style declarations of uninitialized data in
header files.
- Add a few prototypes.
- Clean up warnings resulting from the above.

NB: ioconf.c will still generate a redundant-declaration warning, which
is unavoidable unless somebody volunteers to make `config' smarter.

Change all #includes to follow the current Berkeley style. Some of these
``changes'' are actually not changes at all, but CVS sometimes has trouble
telling the difference.

This also includes support for second-directory compiles. This is not
quite complete yet, as `config' doesn't yet do the right thing. You can
still make it work trivially, however, by doing the following:

rm /sys/compile
mkdir /usr/obj/sys/compile
ln -s M-. /sys/compile
cd /sys/i386/conf
config MYKERNEL
cd ../../compile/MYKERNEL
ln -s /sys @
rm machine
ln -s @/i386/include machine
make depend
make

Make everything compile with -Wtraditional. Make it easier to distribute
a binary link-kit. Make all non-optional options (pagers, procfs) standard,
and update LINT to reflect new symtab requirements.

NB: -Wtraditional will henceforth be forgotten. This editing pass was
primarily intended to detect any constructions where the old code might
have been relying on traditional C semantics or syntax. These were all
fixed, and the result of fixing some of them means that -Wall is now a
realistic possibility within a few weeks.

Make the LINT kernel compile with -W -Wreturn-type -Wcomment -Werror, and
add same (sans -Werror) to Makefile for future compilations.

Removed all patch kit headers, sccsid and rcsid strings, put $Id$ in, some
minor cleanup. Added $Id$ to files that did not have any version info, etc
