Remove stray " in android layout xml files
Convert the android unit test source file to unix newlines
Convert android resource xml files to unix newlines

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

A test application like these ones can do just fine without any icon
at all - there's no need to bundle 8 different extra binary images
just for that.
Change directory to /sdcard before running the unit tests on android

This allows placing the test files in /sdcard/res before running
the test. Previously, the current directory was /, and writing
data into /res isn't possible on non-rooted phones.
Reformat the copyright header of deblocking_neon.S

This makes it identical to the ones in the other files.
Ignore generated files in the new android test project
Remove a redundant definition of WELSEMMS

The same definition already exists in asm_inc.asm.
Avoid unnecessary tabs in macro declarations
Get rid of double spaces in macro declarations
Convert all tabs to spaces in assembly sources, unify indentation

Previously the assembly sources had mixed indentation consisting
of both spaces and tabs, making it quite hard to read unless
the right tab size was used in the editor.

Tabs have been interpreted as 4 spaces in most cases, matching
the surrounding code.
