    string: Fix corrupt GNU_PROPERTY_TYPE (5) size

    For ELF32 the notes alignment is 4 and not 8.

Add license and copyright information to COPYING.NEWLIB as entry (56).

d02cc7a09d strcmp.S: Improve performance for misaligned strings 
Replace the simple byte-wise compare in the misaligned case with a
dword compare with page boundary checks in place.  For simplicity I've
chosen a 4K page boundary so that we don't have to query the actual
page size on the system.

This results in up to 3x improvement in performance in the unaligned
case on falkor and about 2.5x improvement on mustang as measured using
bench-strcmp in glibc.
