[trunk] Update libtiff to 4.0.1 to support BigTIFF. openjpeg/tiff 4.0.1 currently builds on linux/x86_64 and linux/mingw32.

/* $Id: tif_ojpeg.c,v 1.54 2011-05-31 17:05:07 bfriesen Exp $ */
Removed the libs directory containing win32 compiled versions of libpng, libtiff and liblcms. Added a thirdparty directory to include main source files of libtiff, libpng, libz and liblcms to enable support of these formats in the codec executables. CMake will try to statically build these libraries if they are not found on the system. Note that these third party libraries are not required to build libopenjpeg (which has no dependencies).

/* WARNING: The type of JPEG encapsulation defined by the TIFF Version 6.0
specification is now totally obsolete and deprecated for new applications and
images. This file was was created solely in order to read unconverted images
still present on some users' computer systems. It will never be extended
to write such files. Writing new-style JPEG compressed TIFFs is implemented
in tif_jpeg.c.
The code is carefully crafted to robustly read all gathered JPEG-in-TIFF
testfiles, and anticipate as much as possible all other... But still, it may
fail on some. If you encounter problems, please report them on the TIFF
mailing list and/or to Joris Van Damme <info@awaresystems.be>.
Please read the file called "TIFF Technical Note #2" if you need to be
convinced this compression scheme is bad and breaks TIFF. That document
is linked to from the LibTiff site <http://www.remotesensing.org/libtiff/>
and from AWare Systems' TIFF section
<http://www.awaresystems.be/imaging/tiff.html>. It is also absorbed
in Adobe's specification supplements, marked "draft" up to this day, but
supported by the TIFF community.
This file interfaces with Release 6B of the JPEG Library written by the
Independent JPEG Group. Previous versions of this file required a hack inside
the LibJpeg library. This version no longer requires that. Remember to
remove the hack if you update from the old version.

/* What is what, and what is not?
This decoder starts with an input stream, that is essentially the JpegInterchangeFormat
stream, if any, followed by the strile data, if any. This stream is read in
OJPEGReadByte and related functions.
It analyzes the start of this stream, until it encounters non-marker data, i.e.
compressed image data. Some of the header markers it sees have no actual content,
like the SOI marker, and APP/COM markers that really shouldn't even be there. Some
other markers do have content, and the valuable bits and pieces of information
in these markers are saved, checking all to verify that the stream is more or
less within expected bounds. This happens inside the OJPEGReadHeaderInfoSecStreamXxx
functions.
Some OJPEG imagery contains no valid JPEG header markers. This situation is picked
up on if we've seen no SOF marker when we're at the start of the compressed image
data. In this case, the tables are read from JpegXxxTables tags, and the other
bits and pieces of information is initialized to its most basic value. This is
implemented in the OJPEGReadHeaderInfoSecTablesXxx functions.
When this is complete, a good and valid JPEG header can be assembled, and this is
passed through to LibJpeg. When that's done, the remainder of the input stream, i.e.
the compressed image data, can be passed through unchanged. This is done in
OJPEGWriteStream functions.
LibTiff rightly expects to know the subsampling values before decompression. Just like
in new-style JPEG-in-TIFF, though, or even more so, actually, the YCbCrsubsampling
tag is notoriously unreliable. To correct these tag values with the ones inside
the JPEG stream, the first part of the input stream is pre-scanned in
OJPEGSubsamplingCorrect, making no note of any other data, reporting no warnings
or errors, up to the point where either these values are read, or it's clear they
aren't there. This means that some of the data is read twice, but we feel speed
in correcting these values is important enough to warrant this sacrifice. Allthough
there is currently no define or other configuration mechanism to disable this behaviour,
the actual header scanning is build to robustly respond with error report if it
should encounter an uncorrected mismatch of subsampling values. See
OJPEGReadHeaderInfoSecStreamSof.
The restart interval and restart markers are the most tricky part... The restart
interval can be specified in a tag. It can also be set inside the input JPEG stream.
It can be used inside the input JPEG stream. If reading from strile data, we've
consistenly discovered the need to insert restart markers in between the different
striles, as is also probably the most likely interpretation of the original TIFF 6.0
specification. With all this setting of interval, and actual use of markers that is not
predictable at the time of valid JPEG header assembly, the restart thing may turn
out the Achilles heel of this implementation. Fortunately, most OJPEG writer vendors
succeed in reading back what they write, which may be the reason why we've been able
to discover ways that seem to work.
Some special provision is made for planarconfig separate OJPEG files. These seem
to consistently contain header info, a SOS marker, a plane, SOS marker, plane, SOS,
and plane. This may or may not be a valid JPEG configuration, we don't know and don't
care. We want LibTiff to be able to access the planes individually, without huge
buffering inside LibJpeg, anyway. So we compose headers to feed to LibJpeg, in this
case, that allow us to pass a single plane such that LibJpeg sees a valid
single-channel JPEG stream. Locating subsequent SOS markers, and thus subsequent
planes, is done inside OJPEGReadSecondarySos.
The benefit of the scheme is... that it works, basically. We know of no other that
does. It works without checking software tag, or otherwise going about things in an
OJPEG flavor specific manner. Instead, it is a single scheme, that covers the cases
with and without JpegInterchangeFormat, with and without striles, with part of
the header in JpegInterchangeFormat and remainder in first strile, etc. It is forgiving
and robust, may likely work with OJPEG flavors we've not seen yet, and makes most out
of the data.
Another nice side-effect is that a complete JPEG single valid stream is build if
planarconfig is not separate (vast majority). We may one day use that to build
converters to JPEG, and/or to new-style JPEG compression inside TIFF.
A dissadvantage is the lack of random access to the individual striles. This is the
reason for much of the complicated restart-and-position stuff inside OJPEGPreDecode.
Applications would do well accessing all striles in order, as this will result in
a single sequential scan of the input stream, and no restarting of LibJpeg decoding
session.

/* Configuration defines here are:
* JPEG_ENCAP_EXTERNAL: The normal way to call libjpeg, uses longjump. In some environments,
* like eg LibTiffDelphi, this is not possible. For this reason, the actual calls to
* libjpeg, with longjump stuff, are encapsulated in dedicated functions. When
* JPEG_ENCAP_EXTERNAL is defined, these encapsulating functions are declared external
* to this unit, and can be defined elsewhere to use stuff other then longjump.
* The default mode, without JPEG_ENCAP_EXTERNAL, implements the call encapsulators
* here, internally, with normal longjump.
* SETJMP, LONGJMP, JMP_BUF: On some machines/environments a longjump equivalent is
* conviniently available, but still it may be worthwhile to use _setjmp or sigsetjmp
* in place of plain setjmp. These macros will make it easier. It is useless
* to fiddle with these if you define JPEG_ENCAP_EXTERNAL.
* OJPEG_BUFFER: Define the size of the desired buffer here. Should be small enough so as to guarantee
* instant processing, optimal streaming and optimal use of processor cache, but also big
* enough so as to not result in significant call overhead. It should be at least a few
* bytes to accomodate some structures (this is verified in asserts), but it would not be
* sensible to make it this small anyway, and it should be at most 64K since it is indexed
* with uint16. We recommend 2K.
* EGYPTIANWALK: You could also define EGYPTIANWALK here, but it is not used anywhere and has
* absolutely no effect. That is why most people insist the EGYPTIANWALK is a bit silly.

Added a thirdparty directory to include main source files of libtiff, libpng, libz and liblcms to enable support of these formats in the codec executables. CMake will try to statically build these libraries if they are not found on the system. Note that these third party libraries are not required to build libopenjpeg (which has no dependencies).
