Hi,

I have created patches that add basic SELinux support into Emacs.

Currently, if you have SELinux enabled, and you edit a file and then 
store it, the backup file (with the tilde) gets the proper SELinux 
context but the real file loses it. That is caused by "backup by 
renaming". If you set "backup-by-copying" variable to non-nil, the file 
you edited preserves the correct context after saving, but the backup 
file gets the default context (it should get the context of the original 
file).

This causes a lot of problems when editing config files on machines with 
SELinux enabled.

The attached patches modify Emacs so that it preserves SELinux context 
of edited files.
- emacs-1-selinux-config changes the build system to support libselinux
- emacs-2-selinux-get-set-context-fun adds two new functions
   file-selinux-context and set-file-selinux-context
- emacs-3-selinux-backups-on-save modifies the buffer saving functions
   to handle SELinux context

The patch can be applied against a recent version of the repository.

Best regards,
Karel Klic
