Initial Git daemon domain (Revisited Fedoras' Git module). Modified git_selinux.8 to reflect changes.
Unpriv user domain and admindomain run Git daemon in the Git session domain by default. Git session domain is allowed to bind tcp sockets to Git ports.
Changes compared to initial attempt:
Change git_domain attribute to git_daemon attribute.
Removed role git_shell_r; from git.te global declarations, as it is declared in git_user_template.
Move git_system_content attribute from global declarations to git system daemon declarations.
Remove relabel interfaces as those are currently unused.
Split "rwx" interfaces into "manage" and "exec" interfaces as that is likely more usefull and "rwx" just looks unnatural.
Change git_sys_content_type_type(prefix) to git_shared_repository_file_type(type)
Change git_system_user_template to git_user_template.
