move git_version_string into version.c The global git_version_string currently lives in git.c, but doesn't have anything to do with the git wrapper. Let's move it into its own file, where it will be more appropriate to build more version-related functions.

version: add git_user_agent function This is basically a fancy way of saying "git/$GIT_VERSION", except that it is overridable at build-time and through the environment. Which means that people who don't want to advertise their git version (for privacy or security reasons) can tweak it.

include agent identifier in capability string Instead of having the client advertise a particular version number in the git protocol, we have managed extensions and backwards compatibility by having clients and servers advertise capabilities that they support. This is far more robust than having each side consult a table of known versions, and provides sufficient information for the protocol interaction to complete. However, it does not allow servers to keep statistics on which client versions are being used. This information is not necessary to complete the network request (the capabilities provide enough information for that), but it may be helpful to conduct a general survey of client versions in use. We already send the client version in the user-agent header for http requests; adding it here allows us to gather similar statistics for non-http requests.
