…n May 16, 2015)

Includes:
- Add a serial console capable version of the FreeBSD boot manager.
  (freebsd/freebsd-src@653689474)
- Allow one to specify the com port settings for boot0sio.
  (freebsd/freebsd-src@2a49481bc)
- Change from '#' to "//" comment character to allow CPP preprocessing.
  (freebsd/freebsd-src@0a30683aa)
- If the COMSPEED is set to 0, then don't try to initialize the serial
  port and assume that the BIOS has set it up for us. This allows folks
  with a serial-aware BIOS to set the BIOS to speeds above 9600 and
  allow boot0 to just use the existing settings.
  (freebsd/freebsd-src@d9d5c6d6b)
- Remove type 0x4 (FAT12 <32MB) to make room for type 0x7 (NTFS).
  (freebsd/freebsd-src@b87bf48d9)
- A number of small changes to make the 'save choice to disk' safer,
  and re-enable it as default.
  (freebsd/freebsd-src@9b90a7e39)
- Allow boot0cfg to force a PXE boot via boot0 on the next boot.
  - Fix boot0 to check for PXE when using the pre-set setting for the
    preferred slice.
  (freebsd/freebsd-src@2fa7cf8a5)

- Use most of the newer fbsd boot1.S (freebsd/freebsd-src@b730d20)
- Allows you to set the Serial Speed (ie: -S115200)
- Correct line breaks / nicer commandline output when manually entering commands
  - Once the first parameter is entered on the commandline, stop timeout
  - Suppress twiddle when autoboot is off
  - Show current set of flags when making a change
- Allow setting the serial speed (which will also activate RB_SERIAL)
- -D for DUAL makes more sense then -D for Keyboard
- Continue to loader/kernel using an empty commandline (\n) instead of timing out
- Error on unknown flags/cmds
- Move/Reorder some functions
- Use unsigned char / uint8_t to reduce size.
- Add boot.config.5 man file

- Handle Multiple/Dual console drivers in a nicer way
- Add extra functionality to comconsole
- Add sleep/usleep definitions

- Reuse isa_inb/isa_outb from comconsole.c (via extern bootstrap.h)
- Add print RB flags which were passed in (used for debugging)
- Use new cons_probe function
- Updated loader.8 to show change functionality

Use stable names/terms in the Makefile ie COMSPEED and BOOT_COMCONSOLE_SPEED

- Synced with fbsd (freebsd/freebsd-src@433bd38)
- Integrate support for tftp and nfs in one pxeloader
  Remove need for loader_tftp and pxeldr_tftp as special versions
  Update man pages accordingly
- Use RB_SERIAL and RB_MULTIPLE (aka boot_multicons) from sys/reboot.h
  when no keyboard was detected (potential false positive).
- Fix nfs/tftp order for pxeboot

- Default to RB_MULTIPLE/RB_DUAL
Fix Loader:
- Handle serial settings when started by pxeldr
- Move/Merge howto_names table to ../sys/boot.h
Fix comc_set_speed
- Sleep function was not working
- Would never stop after changing speed
Update dloader kenv entries
