fix BGD under screen and remove a build warning in ME
Remove leftover include directories

codec/common no longer contains headers, they're all in
codec/common/inc now.
Build the android cpu-features.o file in codec/common/src

Up until now it was built in codec/common (where all other common
source files were built, until they were split up into
inc/src/x86/arm/arm64).
add encoder interface UT for IDR request
Ignore failures in cleaning android projects

If the android test projects hasn't been built yet, the "make clean"
command will stop at "ant clean" (which fails since build.xml doesn't
exist yet). If this happens, one still would want to run the "make
clean" command to the end, cleaning up any possible intermediate object
files (e.g. from a build for a different platform).

Avoid writing in array index [-1] in DecUT_IntraPrediction

This fixes running the tests when built with clang in debug mode.

This was accidentally broken in 6e815e708 when switched to using
ENFORCE_STACK_ALIGN_1D instead of manually aligning the buffers.

Previously the aligned pointer always had at least 16 bytes of
extra space in the stack before the pointer, so using [-1] was ok,
while now when using ENFORCE_STACK_ALIGN_1D, it's only guaranteed
that the pointer itself is aligned, but not that there's any extra
space before the pointer. Therefore, we need to manually offset
everything by one kiStride extra. (This already was accounted for
in the total number of bytes allocated for the array.)
