Unset the executable bit on source files

Some of these files actually had mixed line endings previously.
Use a correct format string in the unittest JNI wrapper
Fix building the android unittest when targeting older android versions
Remove useless declarations from Application.mk

OPTIM_debug isn't set by anything in this project, and APP_ABI
is set directly when invoking ndk-build - we don't use these
declarations at all.
Remove an unused menu resource file
Remove the stock example icons

at all - there's no need to bundle 8 different extra binary images
just for that.

the test. Previously, the current directory was /, and writing
data into /res isn't possible on non-rooted phones.
Enlarge pLongRefList to avoid accesses out of bounds

This fixes warnings about "array subscript is above array bounds".

All the values assigned into this variable, and compared with this
variable, are int32_t.

This avoids warnings about comparison between signed and unsigned
types.
