libraw: Update to 0.19.3

2019-07-02  Alex Tutubalin <lexa@lexa.ru>
 * Several fixes inspired by OSS-Fuzz
 * LibRaw 0.19.3
 * Note: ABI slightly changed, new variable added at end of class LibRaw
   Generally, all old code should run w/o recompile, but you're warned...

2018-12-24  Alex Tutubalin <lexa@lexa.ru>
 * Fixed possible buffer overrun at Fuji makernotes parser
 * Fixed possible write to NULL pointer at raw2image/raw2image_ex calls.
   Details:
    a) Three different CVE numbers was assigned for single problem:
      CVE-2018-20363, CVE-2018-20364, CVE-2018-20365
    b) The POCs exploits inconsistency in Sinar-4Shot files handling.
     LibRaw 0.19 does not support this files format, so it is not
     subject of exactly same problem
    c) However, additional checks for bayer raw data presence are
     backported from LibRaw-master (development) branch.

 * LibRaw 0.19.2

2018-11-22  Alex Tutubalin <lexa@lexa.ru>
 * Finally: got Sinar 4shot sample, works fine now
 * OpenMP critical sections for malloc/free; extra #ifdefs removed; \ 
bin/dcraw_dist could be built again using Makefile.devel
 * additional checks in parse_phase_one()
 * more checks on file offsets/tag len in parse_minolta
 * more checks in parse_ciff
 * Mempool check reworked
 * Old Leaf (16bit/3color/TIFF) support
 * Fix cameraWB->autoWB fallback
 * Polaroid x530 channel swap; get metadata pointer for Foveon files
 * Fixed Secunia Advisory SA86384
   - possible infinite loop in unpacked_load_raw()
   - possible infinite loop in parse_rollei()
   - possible infinite loop in parse_sinar_ia()

  Note(*): for mobile phones with DNG format recording, only really tested cameras
  are added to supported camera list. Really LibRaw should support any correct DNG.

 * No more built-in support for LibRaw demosaic packs (GPL2/GPL3).
   We're unable to support this (very old code), so we'll be happy to transfer this
   code to some maintainer who wish to work with it.

   In LibRaw 0.19 we provide extension API: user-settable callbacks to be called in
   code points where demosaic pack code was called.

   -  int callbacks.pre_identify_cb(void *) => to be called in \ 
LibRaw::open_datastream
       before call to (standard) identify() function. If this call returns 1, \ 
this means
       that RAW file is identified and all metadata fields are set, so no need to run
       standard identify code.
   - void callbacks.post_identify_cb(void*) => called just after identify(), \ 
but before
       any cleanup code;
   - dcraw_process() callbacks are called before dcraw_process phases (name \ 
speaks for itself):
       	pre_subtractblack_cb, pre_scalecolors_cb, pre_preinterpolate_cb, \ 
pre_interpolate_cb,
	interpolate_bayer_cb, interpolate_xtrans_cb, post_interpolate_cb, \ 
pre_converttorgb_cb,
	post_converttorgb_cb

   All these new callbacks are called with (this) as the only arg.
   To continue LibRaw-demosaic-pack-GPLx support one need to subclass LibRaw, \ 
set needed
   callbacks in (e.g.) constructor code, than these callbacks to be called

 * Better DNG parser:
    - support for DefaultCrop Origin/Size tags (add \ 
LIBRAW_PROCESSING_USE_DNG_DEFAULT_CROP to raw_processing_options to enable)
    - better parsing for nested DNG tags (use tag from RAW IFD, fallback to IFD0 \ 
if no tag in current IFD)
    - DNG PreviewColorspace extracted into dng_levels.preview_colorspace

 * Metadata extraction:
  - Better extraction of camera measured balance (LIBRAW_WBI_Auto and WBI_Measured),
    this not the same as 'as shot' if some preset/manual tune is used.
  - Extraction of camera custom balances (LIBRAW_WBI_CustomN)
  - Nikon data compression tag extracted into  makernotes.nikon.NEFCompression
  - Hasselblad BaseISO and Gain extracted into makernotes.hasselblad
  - Canon multishot params extracted into makernotes.canon.multishot
  - lot of other vendor-specific makernotes data (see data structures \ 
definitions for details).

 * New LibRaw::open_bayer call allows to pass sensor dump w/o metadata directly \ 
to LibRaw:
     virtual int open_bayer(unsigned char *data, unsigned datalen,
	  ushort _raw_width, ushort _raw_height, ushort _left_margin, ushort _top_margin,
	  ushort _right_margin, ushort _bottom_margin,
	  unsigned char procflags, unsigned char bayer_pattern, unsigned unused_bits, \ 
unsigned otherflags,
	  unsigned black_level);
    Parameters:
     data, datalen - buffer passed
     width/height/margins - speaks for itself
     procflags:
     for 10-bit format:
      1: "4 pixels in 5 bytes" packing is used
      0: "6 pixels in 8 bytes" packing is used
     for 16-bit format:
      1: Big-endian data
    bayer_pattern: one of LIBRAW_OPENBAYER_RGGB,LIBRAW_OPENBAYER_BGGR,
                          LIBRAW_OPENBAYER_GRBG,LIBRAW_OPENBAYER_GBRG
    unused_bits: count of upper zero bits
    otherflags:
      Bit 1 - filter (average neighbors) for pixels with values of zero
      Bits 2-4 - the orientation of the image (0=do not rotate, 3=180, 5=90CCW, \ 
6=90CW)
    black_level: file black level (it also may be specified via imgdata.params)

    see samples/openbayer_sample.cpp for usage sample (note, this sample is \ 
'sample only', suited for
    Kodak KAI-0340 sensor, you'll need change open_bayer() params for your data).

 * Color data added/updated/fixed for many cameras

 * Correct data maximum for Fuji X-* cameras

 * Thumbnail processing:
   - JPEG thumbnails: if compiled with libjpeg, color count is extracted into \ 
imgdata.thumbnail.tcolors
   - PPM (bitmap) thumbnails: color count is set according to thumbnail IFD tag
   - PPM16 thumbnails: if LIBRAW_PROCESSING_USE_PPM16_THUMBS set in \ 
raw_processing_options, than thumbnail will be extracted
     as is, not converted to 8 bit. thumbnail.tformat is set to \ 
LIBRAW_THUMBNAIL_BITMAP16 in this case.
     Untested, because it is hard to find RAWs with 16-bit bitmaps.

== Compatibility fixes

 * struct tiff_tag renamed to libraw_tiff_tag
 * pow64f renamed to libraw_pow64f

== Bugs fixed:

 * COLOR(r,c) works correctly on X-Trans files
