...Ops, I broke the old test when porting it to Clay.

 - Should increase performance through usage of a walker
 - No callback invocation for unaltered entries

 - fix retrieval of a file status when working against a newly initialized repository
 - reduce memory pressure
 - prevents a directory from being tested

CMakeLists: no need in split debug/release build

As we no longer expose the transport functions, this is now the only
way to connect to a remote when given an URL instead of a remote name

Transports shouldn't get used outside of the library, so don't expose
accessor functions.

Sockets on Windows are unsigned, so define a type GIT_SOCKET which is
signed or unsigned depending on the platform.

Thanks to Em for his patience with this.

Wuninitialized

Drop STRLEN() macros

There is no need in STRLEN macros. Compilers can do this trivial
optimization on its own.

With GNU toolchain there's no need to split debug/release build.

It's useful to have -O2 in debug envitonment since GCC show more
warnings in this case. -O2 -g works fine.

For release purpose, debug information can be stripted on later stage.

GCC produces several -Wuninitialized warnings. Most of them can be fixed
if we make visible for gcc that git__throw() and git__rethrow() always
return first argument.

I don't think MSVC merges these automatically.
