Shapelib 1.6.0

Changes since v1.5.0:

• shapefil.h: add SHAPELIB_VERSION_MAJOR/MINOR/MICRO, SHAPELIB_VERSION_NUMBER, and SHAPELIB_AT_LEAST macros
• Compiler warning fixes and various code cleanups
• SAHooks: add a void *pvUserData member. ABI change
• SAHooks.FOpen and FClose callbacks: add a void *pvUserData parameter. API and ABI change
• SAHooks.FWrite: make first parameter a const void*. API change
• Distribute LICENSE-LGPL and LICENSE-MIT files instead of COPYING file. Do not distribute INSTALL file
• Use standard integer data types
• Changes to allow building with cmake -DCMAKE_UNITY_BUILD=ON
• Polygon writing: avoid considering rings slightly overlapping as inner-outer rings of others (refs OSGeo/gdal#5315)
• Polygon writing: consider rings at non-constant Z as outer rings (fixes OSGeo/gdal#5315) As noted in code comments, this is an approximation of more complicated tests we'd likely have to do, that would take into account real co-planar testing, to allow detecting inner rings of outer rings in an oblique plane.
• shpopen.c: Communicate why the file size cannot be reached when appending features (OSGeo/gdal#4140) Clearly state why the file size cannot be reached. This is important in order to correctly inform the user and prevent him/her from looking for other reasons. Related to qgis/QGIS#44202
• SHPWriteObject(): prevent potential overflows on 64-bit platforms on huge geometries
• SHPRestoreSHX: update SHX content length even if error occurred
• In creation, uses w+b file opening mode instead of wb followed by r+b, to support network file systems having sequential write only and when using CPL_VSIL_USE_TEMP_FILE_FOR_RANDOM_WRITE=YES (fixes OSGeo/gdal#7801)
• Fix adding features in a .dbf without columns (fixes qgis/QGIS#51247)
• Have matching SOVERSION for CMake and autotools
• Code reformatting
• Enable contrib/csv2shp build with MSVC
• Build contributed utilities via CMake
• Use the the standard BUILD_TESTING CMake variable
• Remove double free() in contrib/shpsrt (CVE-2022-0699)
• SHPRestoreSHX: fix for (64 bit) big endian
• Add config-style support for find_package(shapefile)
• Prevent no-op FSeeks writing dbf & shp records for network filesystem performance
