Don't use plain "throw;", it breaks clang -fno-exceptions build. Bump
revision of boost-headers.

Log message:
Remove patches that are unnecessary in 1.57.0. Fixes build on SunOS.

Log message:
The "rename" rule is a published synonym for the "opt" \ 
transform rule, however
only the latter is supported by cwrappers.  Change them all to "opt" \ 
rules for
consistency and to gain compatibility with cwrappers.

Chamges 1.57.0:
Updated Libraries
Any:
RTTI is not required any more (TypeIndex library is used for RTTI emulation)
Fixed 8958

Asio:
Fixed the kqueue reactor so that it works on FreeBSD.
Fixed an issue in the kqueue reactor which resulted in spinning when using \ 
serial ports on Mac OS.
Fixed kqueue reactor support for read-only file descriptors.
Fixed a compile error when using the /dev/poll reactor.
Changed the Windows backend to use WSASocketW, as WSASocketA has been deprecated.
Fixed some warnings reported by Visual C++ 2013.
Fixed integer type used in the WinRT version of the byte-order conversion functions.
Changed documentation to indicate that use_future and spawn() are not made \ 
available when including the asio.hpp convenience header.
Explicitly marked asio::strand as deprecated. Use asio::io_service::strand instead.

Circular Buffer:
Fixed some warnings and move_if_noexcept from Boost.Move is used

Config:
BOOST_HAS_PRAGMA_DETECT_MISMATCH macro was added

Container:
Added support for initializer_list.
Fixed double destruction bugs in vector and backward expansion capable allocators.

Coroutine:
optionally register stacks with valgrind
10386 MSVC link error in asymmetric_coroutine.hpp: symbol already defined
10536 call to 'begin(...pull_coroutine< R > & c)' is ambiguous

Flyweight:
Added serialization support via Boost Serialization.
flyweight default constructor was made explicit in Boost 1.56, which introduces \ 
a regression in some initialization scenarios. The former non-explicit default \ 
constructor has been restored

Log message:
Fix build on SunOS: transform _XOPEN_SOURCE=500 args where needed, and
revert an upstream commit (https://svn.boost.org/trac/boost/ticket/10350).
The latter part deserves a better fix (finish what upstream neglected).

Changes 1.56.0:
Modularization
Boost version control has migrated to a system using git submodules. This \ 
shouldn't make too much of a difference to users, although the directory \ 
structure is now a bit different.

Parts of some libraries have been moved into different modules, and several new \ 
modules have been extracted from existing code. All header paths should remain \ 
the same. The new modules are:

Assert:
Customizable assert macros. Maintained by Peter Dimov.
Core:
Core utilities used by other libraries, with minimal dependencies. Maintained by \ 
Peter Dimov, Glen Fernandes and Andrey Semashev.
Lexical_Cast:
General literal text conversions, such as an int represented a string, or \ 
vice-versa, from Kevlin Henney.
Throw_Exception:
A common infrastructure for throwing exceptions from Boost libraries, from Emil \ 
Dotchevski.
Winapi:
Windows API declarations without <windows.h>, for internal Boost use.
New Libraries
Align:
Memory alignment functions, allocators, and adaptors, from Glen Fernandes.
Type_Index:
Runtime/Compile time copyable type info, from Antony Polukhin.
