====== patching kernel sources (as of 0.7) ======

* **''kab_unpack_kernel_source'':**
    * uncompress & untar kernel source code to $BUILD_DIR ("build/")
  * **''kab_apply_vserver_patch'':**
    * prepare vserver patch
      * make a copy of $RAW_PATCHNAME to "$RAW_PATCHNAME-as-downloaded" - if it doesn't exists already
      * otherwise restore $RAW_PATCHNAME from $RAW_PATCHNAME-as-downloaded
      * make a copy of $RAW_PATCHNAME to "generic.diff"
      * if patches are given by --vspatch-patch, expire older ones to $SRC_DIR/00-expired
      * if current kernel source version does //not match// the kernel version of the latest patch:
        * look for files named [0-9][0-9]-*.diff and apply them to "generic.diff"
          * therefore replace the name of the patch file to be patched by "generic.diff"
      * extract the value of the "NAME" variable from the current kernel source Makefile
      * replace VERSION PATCHLEVEL EXTRAVERSION and NAME inside kernel source Makefile to:
        * at least attach our signature 
        * fix version information 
      * save the patched vserver patch file to $PATCHNAME
    * apply the patch $PATCHNAME to the kernel source tree
    * return $KERN_FULL_VERSION to calling process
  * **''kab_apply_post_vserver_patch_patches'':**
    * apply patches specified with "--add-patch"
      * this is where linux-*/script/package/builddeb is modified
  * **''kab_compile_and_package''**
