tiff: set palette in the context when specified in TIFF_PAL tag
...
Since image initialization was moved after tag parsing, the
palette needs to be specified in the context and then copied
to the allocated image in init_image().
Fixes a regression with TIFF images that have palette data,
trac issue #230 , file Test_Flate_8bpp.tif.

tiff: add support for SamplesPerPixel tag in tiff_decode_tag()
...
Format detection and internal frame initialization is moved to a
separate init_image() function, which is called when all the tags have
been read, and so both BitsPerSample and SamplesPerPixel information
has been collected.
This fixes decoding of the file 11.tiff from roundup issue #1925 .
Based on a patch by Kostya Shishkov <kostya.shishkov@gmail.com>.

Merge libavcore into libavutil
...
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.
