Add support for a new index.threads config setting which will be used to control the threading code in do_read_index(). A value of 0 will tell the index code to automatically determine the correct number of threads to use. A value of 1 will make the code single threaded. A value greater than 1 will set the maximum number of threads to use. For testing purposes, this setting can be overwritten by setting the GIT_TEST_INDEX_THREADS=<n> environment variable to a value greater than 0.
