boost: bump to version 1.63.0

Remove getchar() patch which has been applied upstream.

Add recommanded post-release patch from upstream to fix 64-bit atomic
operations on 32-bit x86 with gcc versions older than 4.7.

+Subject: [PATCH] Corrected register usage in x86 DCAS asm blocks.
+
+In some of the asm blocks eax was modified as a result of cmpxchg8b but that
+was not reflected in the register constraints. This could cause incorrect code
+being generated.

-To allow building boost/test with uClibc based toolchains with gcc <= 4.8.2 use
