When an ioctl command SW_XXXX is issued, scioctl() checks if the font
appropriate for the specified mode is already loaded. The check was
correctly done for 8 line and 16 line fonts, but not for 14 line font.
The symbols FONT_8, FONT_14 and FONT_16 were defined as numbers but
were sometimes treated as bit flags. They are now defined as bit
flags.
2) screen blinking (two fixes)
Removed a redundant call to timeout() in do_bell().
Don't let blink_screen() write to the video buffer if the screen is in
the graphics (UNKNOWN) mode.
3) screen saver timeout
The ioctl command CONS_BLANKTIME sets the screen saver's timeout. The
value of zero will disable the screen saver. If the screen saver is
currently running it should be stopped.
4) border color and destructive cursor (two fixes)
The border color and the cursor type can be changed via escape
sequences. But only VGA can change the border color and set the
cursor type to destructive (CHAR_CURSOR) in the current syscons.
scan_esc() failed to check this.

Add some other improvements:
- swapsize is now detected if no value was specified.
- resvport is used by default
- merged code for setting/showing mount options for root/swap.

- enabled SMP_AUTOSTART, since it's the desired working mode and it's

Sigh. The CDIOREADTOCENTRYS did a copyout() of its own, and thus has
been unusable for me for this work. Too bad it didn't simply stuff
the max 100 entries into the struct ioc_read_toc_entry, but relied on
a user supplied data buffer instead. :-( I now had to reinvent the
wheel, and created a CDIOREADTOCENTRY ioctl command that can be used
in a kernel context.
While doing this, i noticed the following bogosities in existing CD-ROM
drivers:
wcd: This driver is likely to be totally bogus when someone tries
two succeeding CDIOREADTOCENTRYS (or now CDIOREADTOCENTRY)
commands with requesting MSF format, since it apparently
operates on an internal table.
scd: This driver apparently returns just a single TOC entry only for
the CDIOREADTOCENTRYS command.
I have only been able to test the CDIOREADTOCENTRY command with the
cd(4) driver. I hereby request the respective maintainers of the
other CD-ROM drivers to verify my code for their driver. When it
comes to merging this CD-ROM multisession stuff into RELENG_2_2 i will
only consider drivers where i've got a confirmation that it actually
works.
simplifies some assumptions and stops some code compile problems.
This should fix the compile hiccup in PR#3491, but smp kernel profiling
isn't likely to be fixed by this.
