make.bat: add Makefile functionality for Windows

Converted the Makefile functionality into several bat files to better
support building on Windows. All targets have been introduced in the
make.bat file, except for "cov" and "format".

Running make.bat with no arguments runs the all target per default,
just like Makefile.
If an argument is supplied, it must be one of all, cover, deps,
integ, test, vet, or updatedeps.

For example

  > make.bat test

runs the test target.

+### Building Consul on Windows
+
+Make sure Go 1.4+ is installed on your system and that the Go command is in your
+%PATH%.
+
+For building Consul on Windows, you also need to have MinGW installed.
+[TDM-GCC](http://tdm-gcc.tdragon.net/) is a simple bundle installer which has all
+the required tools for building Consul with MinGW.
+
+Install TDM-GCC and make sure it has been added to your %PATH%.
+
+If all goes well, you should be able to build Consul by running `make.bat` from a
+command prompt.
+
+See also [golang/winstrap](https://github.com/golang/winstrap) and
+[golang/wiki/WindowsBuild](https://github.com/golang/go/wiki/WindowsBuild)
+for more information of how to set up a general Go build environment on Windows
+with MinGW.
