rename worktree test helper function
introduce a helper function for use by work tree init test
use a dedicated file for the work tree lock
document how work tree locking will work
use flock(2) because open(2) O_NONBLOCK also enables non-blocking I/O
lock meta data files in worktree correctly
implement worktree open and close operations
assume good path input in got_worktree_init()
add function to read worktree meta data file
rename worktree set_head() operation to change_head()
fileindex update function probably won't be needed after all
store a path prefix in the worktree; will be used for subtree checkout
file_index -> fileindex
rename file_index -> fileindex
