Improve copying and moving weak refs.
...
Fixes a bug introduced (replacing a similar bug) in the last rewrite of
objc_moveWeak. This version should now be correct.
objc_copyWeak was implemented in a naive way, which had a lot more
overhead than required.

Simplify the weak code.
...
Rather than tracking all of the locations of weak pointers, keep a weak
refcount. This should also make it easier to add finer-grained locking to weak
references.

Add objc-class.h to objc headers

to obtain the declarations contained in objc/message.h and
objc/runtime.h nowadays. This commit adds this header to achieve
out-of-the-box compatibility with these applications.

build: add compatibility symlink for block headers
...
On FreeBSD and OSX, the block runtime functions are defined on a Block.h
and a Block_private.h headers on the include path as opposed to
libobjc2's objc/blocks_runtime.h and objc/blocks_private.h respectively.
This commit amends libobjc2's install routine to create the
FreeBSD-style headers as symlinks to the ones provided by libobjc2 for
improved compatibility.
