Umang JainandLaurent Pinchart 51bfc82392 android: jpeg: exif: Pad extra byte only for ASCII format in setString() 
The EXIF standard states that EXIF_FORMAT_UNDEFINED shall not be
terminated with NULL. The patch implements this particular detail and
pad one extra byte for EXIF_FORMAT_ASCII to null-terminate strings.

Laurent Pinchart 7720c4aefa android: jpeg: exif: Use reentrant localtime_r() 
The std::localtime() function isn't thread-safe, and we have no
guarantee whether other threads in the camera service may or may not
call it. Replace it with localtime_r(). This requires switching from
ctime to time.h, as there is no std::localtime_r() function.

Umang JainandLaurent Pinchart 6f09a619cc android: jpeg: Support an initial set of EXIF metadata tags 
Create a Exif object with various metadata tags set, just before
the encoder starts to encode the frame. The object is passed
directly as libcamera::Span<> to make sure EXIF tags can be set
in a single place i.e. in CameraDevice and the encoder only has
the job to write the data in the final output.
