boot.cfg.5: banner can span up to 12 lines, and not 10 like stated.

For the record, the value is set by the BOOTCFG_MAXBANNER macro defined
in sys/lib/libsa/bootcfg.h.

boot.cfg.5: Note that userconf can be used multiple times

Additionally:
- Make it easier for the reader to learn which keywords can be used
multiple times
- Use multiple "userconf" lines in the EXAMPLES section, conveniently
listing the current DRM drivers that a user might need to disable to
troubleshoot "blank screen after boot" issues.

Remove workaround for ancient HTML generation code.

New sentence, new line. Use more markup. Bump date for previous.

Add support for passing saved entropy (random seed file) to the kernel
from the bootloader. This can fix the problem of poor quality keys
for other kernel modules which call arc4random() early in kernel startup
(NFS startup, in particular, causes this).

We continue to rely on the etc/rc.d/random_seed script to save entropy
to the seed file at shutdown and erase the seed file at startup.

Boot loader support implemented only for i386 and amd64 ports for now but
it should be easy for other ports to do the same or similar.

Support userconf(4) command in boot(8)/boot.cfg(5) on i386/amd64.

Fix syntax for load command. There is no = sign when specified as a command
vs being a boot.cfg directive.

Add support for multiple commands separated by semi-colons on menu lines
in boot.cfg.
e.g.
menu=Boot with module foo:load=/foo.kmod;boot

- Give x86 BIOS boot the ability to load new style modules and pass them
into the kernel. Based on a patch by jmcneill@, with many fixes and
improvements by me.

- Put MEMORY_DISK_DYNAMIC and MODULAR into the GENERIC kernels, so that
you can load miniroot.kmod from the boot blocks and boot into the
installer!

If a menu line in boot.cfg has an empty description, then re-use the
command as the description. For example,

menu=:boot netbsd -s

now works like

menu=boot netbsd -s:boot netbsd -s

i386 and amd64 share a bootloader, so this should work on both.

Thanks to xtraeme@ and bouyer@ for pointing out this oversight.

While boot.cfg support is currently i386 only, it is hoped that its use
will be extended to other appropriate ports in future. Note as such in the
bugs section.

This is an MI man page, so should not be flagged as i386 in the header.

Add support for /boot.cfg configuration file in x86 boot loader.
This allows easy configuration of banner text, console device and timeout
as well as allowing menus of commands to be displayed. If /boot.cfg
is not present, then the existing behaviour does not change.

The sections in the boot loader source are surrounded by #ifdef SMALL
allowing this functionality to be removed if space is at a premium.
