add support for running Java Android applications

We have now fixed configuration issues (#1857) and several other issues in DynamoRIO (DynamoRIO/dynamorio#1912) and can now run at least the calculator app under plain DR.

However, running it under Dr. Memory still hits some problems.

One is #1880, which I have a fix for.

Another is an mmap conflict, which I am presumably fixing by moving the preferred base:

04-07 00:53:04.587 28591 28591 W art     : Failed to open oat file '/data/dalvik-cache/arm/system@framework@boot.oat' referenced from image /data/dalvik-cache/arm/system@framework@boot.art: Failed to allocate ElfFile reservation for /data/dalvik-cache/arm/system@framework@boot.oat: Failed to mmap at expected address, mapped at 0xb125e000 instead of 0x7138e000 : Requested region 0x7138e000-0x74953000 overlaps with existing map 0x73800000-0x739ca000 (/data/local/tmp/build_DRtoo_android_dbg/bin/debug/libdrmemorylib.so)

After fixing those, I'm seeing strange kernel crashes when I run calc under DrM and it's not clear exactly why.

If I run with -leaks_only -no_count_leaks -no_track_allocs we hit an app crash:

This is where I'm having to leave this until I get more time. Hopefully others can try running some small apps and help contribute to figuring out what the problems are.
