API: deprecate 'bpp' member in favor of 'prec'
...
in opj_image_comp and opj_image_comptparm structures.
bpp was redundant with prec, and almost never set by the library, except
by opj_image_create(). This change should hopefully not impact existing,
working, users of the API, which should already have used prec to get
things working.

jp2: convert: fix null pointer dereference
...
Tile components in a JP2 image might have null data pointer by defining a
zero component size (for example using large horizontal or vertical
sampling periods). This null data pointer leads to null image component
data pointer, causing crash when dereferenced without != null check in
imagetopnm.
Add != null check.
This commit addresses #1152 (CVE-2018-18088).
