Stefan Kost 5e3f448afb exiftag: reflow the code 
Move the warning on unsupported units to the swicth-case. Move fetching the
pending tags down to where we use them.

Stefan Kost 8ffe4445f6 exiftag: set value=1 if we found the token 
Otherwise we never write the tag. This would also be consistent with the code in
deserialize_scene_type().

Víctor Manuel Jáquez Leal 35c1cf16d9 tag: exif: register common tags from tag library 
Exif uses tags like  image-vertical-ppi or image-horizontal-ppi which are
registered in gst_tag_register_musicbrainz_tags(), but neither GstExifReader
nor GstExifWriter register them.

Tim-Philipp Müller 3ecb114b61 tag: fix leak when parsing undefined EXIF tag into tag list

Thiago Santos adcb6e642d tags: exif: Fix bug in inner ifd parsing 
Do not use the result of inner ifd's parsing to increment
the current tag index. The reasons are:

1) The function returns a boolean.
2) The inner ifd's tags are in a separate table, so they shouldn't
interfere with its parent ifd table parsing.
