Revamp the ways in which the library can be built (#621) This change allows to link the system version of libgit2 statically. Since `-tags static` is already used for the bundled version of the library and to avoid breaking old workflows, `-tags static,system_libgit2` is now used to select that. This means that the valid combinations are: | Flag | Effect | |-------------------------------|-----------------------------------------------| | _No flags_ | Dynamically-linked against the system libgit2 | | `-tags static,system_libgit2` | Statically-linked against the system libgit2 | | `-tags static` | Statically-linked against the bundled libgit2 | Note that there is no way to express dynamically linking against the bundled libgit2 because that makes very little sense, since the binaries wouldn't be able to be distributed. If that's still desired, the `PKG_CONFIG_PATH` environment variable can set before building the code. [`Makefile`](https://github.com/libgit2/git2go/blob/master/Makefile) has an example of how it is used in the CI.

Improve the static build script This change: * Uses the installed version of both the library and the pkgconfig file, which fixes path resolution on Ubuntu Xenial. * Uses quoting liberally so that paths with spaces in them are correctly handled. * Moves the build+install directories to static-build/ in the git2go repository to avoid having a dirty vendor/libgit2 checkout.

fix buldled static build on Windows/MinGW (#761) seems like need more libraries in LDFLAGS: * ws2_32 for socket, connect, htonl, etc * ole32 for CoInitializeEx * rpcrt4 for UuidCreate * crypt32 for CertFreeCertificateContext

Declare forward-compatibility with libgit2 v1.2.0 #minor (#800) We can't yet ship a fully libgit2 v1.2.0-compatible library due to a missing public symbol, but we can allow the v1.1.0-era codebase to link against libgit2 v1.2.0 in the meantime.
