This PR (and fix981_canonAutoFocus2) use a decoder listed in TiffMappingInfo to
decode Exif.Canon.AFInfo. The decoding function "manufactures" Exif tags such as
Exif.Canon.AFNumPoints from the data in Exif.Canon.AFInfo. These tags must never
be written to file and are removed from the metadata in
exif.cpp/ExifParser::encode().
Three of the tags created (AFPointsInFocus,AFPointsSelected, AFPrimaryPoint) are
bitmasks. As the camera can have up to 64 focus points, the tags are a 64 bit
mask to say which points are active. The function printBitmask() reports data
such as 1,2,3 or (none).
This decoding function decodeCanonAFInfo() added to TiffMappingInfo manufactures
the new tags. Normally, tags are processed by the binary tag decoder and that
approach was taken in branch fix981_canonAf. However, the binary tag decoder
cannot deal with AFInfo because the size of some metadata arrays cannot be
determined at compile time.
This removes the AF from the name of the lens thus matching the name
that lensfun and exiftool determine.

- Regression test for missing bounds check in MemIo::seek()
- Add bounds check to MemIo::seek(), this fixes CVE-2019-13504
(cherry picked from commit bd0afe0390439b2c424d881c8c6eb0c5624e31d9)
Additional fixes for 0.27:
- Add fix for the linux variant of MemIo::seek
- Change type of variable from unsigned to signed
Note that the problem occurs when data_size is less than header_size
what causes a buffer overflow in &data[i]

* Fix 582 Add support for FocusPosition in Sony RAW files
* Thanks to @boardhead sonyFpCrypt() works correctly. Removed debug code. Fixed typos.
* Update doc/templates/Makefile to process Sony2Fp
* Following review by @boardhead. Renamed sonyFpCrypt() as sonyTagDecipher().
* Fixed writing the tag thanks to @boardhead explaining encipher/decipher.
Sadly, ArrayCfg/crpyt does not know if he's encrypting/decrypting.
I've added a sniff in TiffEncoder::visitBinaryArrayEnd to avoid changing the API.
* Added URL to discussion concerning sonyTagCipher()
* make sonyTagCipher() a static function with no external visibility.
* Add README-SAMPLES.md and remove exiv2samples.1
* Remove samples man page from CMake
* Add all sample programs to Doxygen.
* Adding links to source code on exiv2.org

This seems to have been caused by duplicate work between master branch
and 0.27-maintenance branch, as commit 3b48249eeb350301dfb3efa3ba6f7d7b162455be
had already got that right.
