Make TIFFTAG_CFAPATTERN variable count 
The TIFFTAG_CFAPATTERN tag (33422) from TIFF/EP, recently introduced in libtiff
3363eda09d / http://bugzilla.maptools.org/show_bug.cgi?id=2457
is described as having a fixed count of 4.
But the TIFF/EP spec says this should support a variable count (= CFARepeatRows * CFARepeatCols):

TIFF/EP, ISO 12234-2:2001

a8193c438f EXIF 2.32 and GPS tags and functionality upgraded. 
- Existing EXIF field definition of tags is upgraded to EXIF version 2.3.2
- EXIF-GPS structure, tags and access functions are added as special CustomDirectory (like it was done for EXIF).
- Test program custom_dir_EXIF_231.c added to test writing/reading of EXID IFD and GPS IFD tags
  and to highlight some quirks of IFD-handling and peculiarities of reading/writing the different data types.
- Reading error for FileSource and SceneType tags corrected.

- EXIF_GPS_upgrade rebased onto c8c5309b76 (Merge branch 'Rational2DoublePrecision_correction' into 'master')
and adapted:
- tif_dirinfo.c:         All rational tags set to TIFF_SETGET_FLOAT but only the GPSTAG_ tags set to TIFF_SETGET_DOUBLE.
- custom_dir_EXIF_231.c: Editorials amended and gcc warnigs fixed.
- CMakeLists.txt: add_test(NAME "custom_dir_EXIF_231"  COMMAND "custom_dir_EXIF_231")  added.

the -I option for the GNU diff and the FreeBSD diff
behaves differently regarding escaping the ( ) and |

By using two -I option, we avoid using such charracters.

tif_fax3.h: check for buffer overflow in EXPAND2D before "calling" CLEANUP_RUNS() 
fixes #179

this fixes the regression introduced in 02bb0175 / 72c4acef
( merge request !110 )

It may be a better fix to do the overflow check in SETVALUE() but the
macro do { } while(0) construct makes it difficult to quit the loop
properly.

Rational with Double Precision Upgrade

6df997c786 Rational with Double Precision Upgrade 
Unfortunately, custom rational tags (TIFF_RATIONAL with field_bit=FIELD_CUSTOM) are defined as TIFF_SETGET_DOUBLE
but for the reading interface and LibTiff internally they are stored ALLWAYS as floating point SINGLE precision.
Double precision custom rational tags are not supported by LibTiff.

For the GPS tags in WGS84 a higher accuracy / precision is needed.
Therefore, this upgrade is made, keeping the old interface for the already defined tags and allowing a double precision definition,
as well as calculating rationals with higher accuracy / precision.
This higher accuracy can be used for newly defined tags like that in EXIF/GPS.

Refer also to the very old Bugzilla issue 2542 (#69)

A test file rational_precision2double.c is added, which shows prevention of the old interface to the already defined custom rational tags
with the standard library as well as with the upgraded library.

Also TIFFTAG_XRESOLUTION, TIFFTAG_YRESOLUTION, TIFFTAG_XPOSITION, TIFFTAG_YPOSITION amended from TIFF_SETGET_DOUBLE to TIFF_SETGET_FLOAT and testcase inserted in rational_precision2double.c
