c2e3e002f6 Disable build/install of boot.help until we sort out how to construct it 
in the makeworld environment.

8719fada36 Reformat help to improve subtopic display appearance, other minor 
cleaning.  The 'help' command in the loader should now be usable and
hopefully informative.

7ac90f7d65 Drop the familiar 'text=xxxx data=xxxx bss=xxxx ...' display while 
loading.  This eliminates noise when loading boot/loader; and when
loading a kernel, they generally flash by too fast to be
intelligible anyway.

9888bdcd29 boot1: Eliminate EDD detection and optional use of disk packet 
interface.  Do some general consistency fixes and space optimizations.
Use of some freed-up space to defend against possible BIOS misfeatures.

up space for this.

af1f6e0673 Implement a simple LRU block cache. By default this is initialised to 16k, 
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.

dc8be6a8f5 - Add a new command 'lsdev' to list devices which might be likely to host 
filesystems.
 - New 'help' command and data in the help.* files (not yet installed),
   provides topic and subtopic help, indexes, etc.
 - Don't crash if the user tries to set an invalid console.  Be helpful
   instead.
 - Expand tabs (badly) on the i386 video console.
 - Some minor cosmetic changes.

93d51dcaf9 Treat all options as toggles (ie. -c -c is the same no -c). Since

7fa25d805a biosboot compatibility fix: 
Read boot.help before parsing boot.config.  We were parsing
boot.config first, which could result in boot.help being read
from a different location (or not found), which would probably
just cause surprise, without being useful.
