  TurboJPEG C API: Add BMP/PPM load/save functions
  
  The main justification for this is to provide new libjpeg-turbo users
  with a quick & easy way of developing a complete JPEG
  compression/decompression program without requiring them to build
  libjpeg-turbo from source (which was necessary in order to use the
  project-private bmp API) or to use external libraries.  These new
  functions build upon significant enhancements to rdbmp.c, wrbmp.c,
  rdppm.c, and wrppm.c which allow those engines to convert directly
  between the native pixel format of the file and a pixel format
  ("colorspace" in libjpeg parlance) specified by the calling program.
  rdbmp.c and wrbmp.c have also been modified such that the calling
  program can choose to read or write image rows in the native (bottom-up)
  order of the file format, thus eliminating the need to use an inversion
  array.  tjLoadImage() and tjSaveImage() leverage these new underlying
  features in order to significantly improve upon the performance of the
  old bmp API.
  
  Because these new functions cannot work without the libjpeg-turbo
  colorspace extensions, the libjpeg-compatible code in turbojpeg.c has
  been removed.  That code was only there to serve as an example of how
  to use the TurboJPEG API on top of libjpeg, but more specific, buildable
  examples now exist in the https://github.com/libjpeg-turbo/ijg
  repository.
