• Update devel/icu to 57.1.
• Clean up the Makefile.
• Follow some upstream recommendations (--with-data-packaging=archive, --disable-renaming, -DICU_NO_USER_DATA_OVERRIDE).
• Patch makefiles to install static libraries with INSTALL_DATA so they aren't stripped.
• Patch config/mh-bsd-gcc to sync with config/mh-linux-gcc.
• Fix endianness detection in ICU. The code wanted to use BYTE_ORDER defined in machine/endian.h, but this isn't visible because ICU is compiled with _XOPEN_SOURCE. Patch the code to use _BYTE_ORDER instead.
• Compile ICU with C++11 compiler to enable move constructors.
• Patch ICU to fix a problem with atomics in the case of a C++11 compiler without C++11 header <atomic> (like Clang on FreeBSD 9).
• Bump all ports that depend on it due to library version change.
• Add USES=compiler:c++0x to some ports that pick up -std=c++0x from ICU pkgconfig files.
• Add USES=compiler:c++11-lib to graphics/libcdr01 because it also needs a C++11 runtime library now. Add this to all ports that depend on it so their executables load the right libstdc++.so on FreeBSD 9.
