'RELENG_3_5_0_RELEASE'.

This commit was manufactured to restore the state of the 3.5-RELEASE image.
Releases prior to 5.3-RELEASE are omitting the secure/ and crypto/ subdirs.

MFC:

1999-02-06T14:27:46+00:00

Rename "source" as "include". Make it capable of including forth source,
while stripping #@- functionality (in the BOOT_FORTH case).

Add builtin "more". (This is already in help.common -- must got into one
of Mike's MFC).

Make bf_run return ficlExec() result code. Push "interpret" on the
execution stack before calling ficlExec() (not doing this was a bug,
if we want ficlExec() to recurse).

Add EXCEPTION and MEMORY-ALLOC word sets.

Fix "evaluate" to respect buffer size.

Make builtins "throw" errors instead of pushing them on the stack. Move
error message printing from bf_command() to bf_run().

Make builtins state-aware.

Fix "type" not to use fixed sized buffers.

Add version words to ficl.

Add trace facility to ficl.

Add words $ and % to replace @ and - in "include".

Replace duplicated "old" linker set definitions with an include of

1999-01-16T03:25:24+00:00

.  Note, this isn't used on the i386.

Fall back to /boot/boot.conf, if /boot/loader.rc was not fount. This is

to cover the transition period.

Implement a simple LRU block cache. By default this is initialised to 16k,

1998-11-02T23:28:11+00:00

and will bypass transfers for more than 8k.  Blocks are invalidated after
2 seconds, so removable media should not confuse the cache.

The 8k threshold is a compromise; all UFS transfers performed by
libstand are 8k or less, so large file reads thrash the cache.
However many filesystem metadata operations are also performed using
8k blocks, so using a lower threshold gives poor performance.

Those of you with an eye for cache algorithms are welcome to tell me
how badly this one sucks; you can start with the 'bcachestats' command
which will print the contents of the cache and access statistics.

Export an interface for presetting the ISA PnP read port address.

1998-10-22T20:20:51+00:00

Make the EISA ID formatter generally available

Make ISA PnP work. This successfully enumerates as many ISA devices as I

1998-10-21T20:07:05+00:00

can fit into my test machine.

 - Move to using STAILQs rather than ad-hoc singly-linked lists.
 - Use a mostly procedural interface to the PnP information.  This
   improves data-hiding.

Implement a new linker-set technique (currently on i386 only but should work
on Alpha as well).  This is a good candidate for replacing the current
gensetdefs cruft completely.

loader <-> kernel preload module interface constants moved to common file.

Remove Mike's explicit data structures for dependency info.  This is
done via DT_NEEDED etc in the dynamic section for now.  This may need
to be revisited later on.
