9e6f796b0d o Merge <machine/ansi.h> and <machine/types.h> into a new header
called <machine/_types.h>.
o <machine/ansi.h> will continue to live so it can define MD clock
  macros, which are only MD because of gratuitous differences between
  architectures.
o Change all headers to make use of this.  This mainly involves
  changing:
    #ifdef _BSD_FOO_T_
    typedef	_BSD_FOO_T_	foo_t;
    #undef _BSD_FOO_T_
    #endif
  to:
    #ifndef _FOO_T_DECLARED
    typedef	__foo_t	foo_t;
    #define	_FOO_T_DECLARED

c7181950f3 Reimplement malloc/free debugging that includes the offending file:line
info.  This turned out to be rather useful on ia64 for tracking down
malloc/free problems.
Detect duplicate free()'s - otherwise these show up as a guard1 failure
and it looks like corruption instead of something simple like a second
free() where there shouldn't be.
Deal with libz using libc headers and not seeing the malloc/free stuff that
we provide in libstand.  Do similar nastiness to what is done for bzlib.

Tested on: i386, ia64 (compile, run)

88d85c15ef This commit adds basic support for the UFS2 filesystem. The UFS2
filesystem expands the inode to 256 bytes to make space for 64-bit
block pointers. It also adds a file-creation time field, an ability
to use jumbo blocks per inode to allow extent like pointer density,
and space for extended attributes (up to twice the filesystem block
size worth of attributes, e.g., on a 16K filesystem, there is space
for 32K of attributes). UFS2 fully supports and runs existing UFS1
filesystems. New filesystems built using newfs can be built in either
UFS1 or UFS2 format using the -O option. In this commit UFS1 is
the default format, so if you want to build UFS2 format filesystems,
you must specify -O 2. This default will be changed to UFS2 when
UFS2 proves itself to be stable. In this commit the boot code for
reading UFS2 filesystems is not compiled (see /sys/boot/common/ufsread.c)
as there is insufficient space in the boot block. Once the size of the
boot block is increased, this code can be defined.

Things to note: the definition of SBSIZE has changed to SBLOCKSIZE.
The header file <ufs/ufs/dinode.h> must be included before
<ufs/ffs/fs.h> so as to get the definitions of ufs2_daddr_t and
ufs_lbn_t.

Still TODO:
Verify that the first level bootstraps work for all the architectures.
Convert the utility ffsinfo to understand UFS2 and test growfs.
Add support for the extended attribute storage. Update soft updates
to ensure integrity of extended attribute storage. Switch the
current extended attribute interfaces to use the extended attribute
storage. Add the extent like functionality (framework is there,
but is currently never used).

59049318b6 Added new bsd.incs.mk which handles installing of header files
via INCS.  Implemented INCSLINKS (equivalent to SYMLINKS) to
handle symlinking include files.  Allow for multiple groups of
include files to be installed, with the powerful INCSGROUPS knob.
Documentation to follow.

Added standard `includes' and `incsinstall' targets, use them
in Makefile.inc1.  Headers from the following makefiles were
not installed before (during `includes' in Makefile.inc1):

	kerberos5/lib/libtelnet/Makefile
	lib/libbz2/Makefile
	lib/libdevinfo/Makefile
	lib/libform/Makefile
	lib/libisc/Makefile
	lib/libmenu/Makefile
	lib/libmilter/Makefile
	lib/libpanel/Makefile

Replaced all `beforeinstall' targets for installing includes
with the INCS stuff.

Renamed INCDIR to INCSDIR, for consistency with FILES and SCRIPTS,
and for compatibility with NetBSD.  Similarly for INCOWN, INCGRP,
and INCMODE.

Consistently use INCLUDEDIR instead of /usr/include.

gnu/lib/libstdc++/Makefile and gnu/lib/libsupc++/Makefile changes
were only lightly tested due to the missing contrib/libstdc++-v3.
I fully tested the pre-WIP_GCC31 version of this patch with the
contrib/libstdc++.295 stuff.

These changes have been tested on i386 with the -DNO_WERROR "make
world" and "make release".

9d703dcfed Add splitfs vfs layer into libstand, which allows loading big kernels and
modules split across several physical medias. Following is how it works:

The splitfs code, when asked to open "foo" looks for a file "foo.split"
which is a text file containing a list of filenames and media names, e.g.

	foo.aa "Kernel floppy 1"
	foo.ab "Kernel floppy 2"
	foo.ac "Kernel and modules floppy"

For each file segment, the process is:

- try to open the file
- prompt "Insert the disk labelled <whatever> and press any key..."
- try to open the file
- return error if file could not be located

RE team is free to use this feature in the upcoming 5.0-DP1.

3ed05b7b89 Add the following functions/macros to support byte order conversions and
device drivers for bus system with other endinesses than the CPU (using
interfaces compatible to NetBSD):

- bwap16() and bswap32(). These have optimized implementations on some
  architectures; for those that don't, there exist generic implementations.
- macros to convert from a certain byte order to host byte order and vice
  versa, using a naming scheme like le16toh(), htole16().
  These are implemented using the bswap functions.
- stream bus space access functions, which do not perform a byte order
  conversion (while the normal access functions would if the bus endianess
  differs from the CPU endianess).

htons(), htonl(), ntohs() and ntohl() are implemented using the new
functions above for kernel usage. None of the above interfaces is currently
exported to user land.

Make use of the new functions in a few places where local implementations
of the same functionality existed.

d118ae3895 Fix a bug in lseek which caused the loader to fail on some gzipped
kernels.  The error message was "elf_loadexec: cannot seek".

Libstand maintains a read-ahead buffer for each open file, so that
it can read in chunks of 512 bytes for greater efficiency.  When
the loader tries to lseek forward in a file by a small amount, it
sometimes happens that the target file offset is already in the
read-ahead buffer.  But the lseek code simply discarded the contents
of that buffer and performed a seek directly on the underlying
file.  This resulted in an attempt to seek backwards in the file,
since some of the data has already been read into the read-ahead
buffer.  Gzipped data streams cannot seek backwards, so an error
was returned.

This commit adds code which checks to see if the desired file offset
is already in the read-ahead buffer.  If it is, the code simply
adjusts the buffer pointer and length, thereby avoiding a reverse
seek on the gzipped data stream.

I incorporated a suggestion from Matt Dillon which saved a little
bit of code in this fix.

b9f1a189bc When TFTP tries to open a file, it is expecting struct open_file
member f_devdata to be a pointer to a socket number.  When currdev
is "pxe", that assumption is correct.  When currdev is "disk*", that
assumption is incorrect.

1b55b7a246 Disable the end guard for now.
The test for failing the end guard was always triggering (and was reported as
such in compiler warnings).  This is a temporary band-aid until I can work
out what's really going on.

6ff92c14b7 Implement readahead buffering for non-raw files. This drastically improves
the efficiency of byte-by-byte read operations on filesystems not already
supported by the block cache (especially NFS).

This should be a welcome change for users booting via PXE, as the loader
now reads its startup files almost instantly, instead of taking tens of
seconds.
