Assorted bug fixes.

keyboard.c
- Call tcsetattr() in VGLKeyboardEnd() to restore tty, only when
  tty attributes have been previously saved.
  PR: misc/9524
  Submitted by: Katusyuki 'kei' Maeda (kei@nanet.co.jp)
- Set up the tty raw mode correctly.

main.c
- Restore VESA_800x600 raster text mode correctly in VGLEnd().
  Submitted by: des

text.c
- Allocate the correct size of a font buffer in VGLSetFontFile().
  I forgot the submitter ;-(

simple.c, bitmap.c
- Fix address calculation for the VGA mode X in VGLGetXY() and
  VGLBitmapCopy().
- Fix typo (dsty -> dstx) in __VGLBitmapCopy().
