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.

Some servers take a long time to answer and expect us to keep sending
want lines; otherwise they close the connection. Avoid this by waiting
for one second for the server to answer. If the timeout runs out,
treat is as a NAK and keep sending want lines.

Only signal that we need a pack if we do need it and don't send a want
just because it's the first. If we don't need to download the pack,
then we can skip all of the negotiation and just return success.
