2006-12-05: October Snapshot: Patchlevel 3

 * Major upgrade of DICE to newly released version 3.1.0:
   Fixes several problems, including those addressed in the second patch
   and a stack underflow problem that became apparent in the DOpE
   package provided with the additional EMSCB source tarball
   See Changelog file in the DICE source tree included in this snapshot
   
 * Adaptations to new DICE version in various user-level packages:
   * Instead of [prealloc], IDL interfaces now use [prealloc_client] and/or
     [prealloc_server]; see Section 1.6.4 of the DICE user manual for more
     details
   * Reverted preliminary fixes for loader and names package from
     patchlevel 2
     
 * roottask:
   * Fixed the use of incorrect constants in the client library
   * Fixed client-side and server-side code of rmgr_set_task_id():
     This function no longer registers a new name, but just tries to set the
     quota for a given task
   * Added missing bounds checking on names registry
   * Removed obsolete code for handling old sigma0 protocol
   
 * Fixed C++ compatibility of libio interface:
   adapted packages: generic_io, l4io
   
 * Fixed typo in inline documentation of sigma0 lib's header file
   concering cacheable/noncacheable memory mappings
 * Added missing documentation of 'all_sects_writable' directive in
   loader package
 * C++ compatibility fix in semaphore library
 * Fixes related to C standards and removal of obsolete code for older
   compilers in the the l4sys system-call bindings

 * Minor fixes in log package
 * Changed default configuration of non-driver L4Linux so that it indeed
   does not touch any hardware (i.e., removed serial driver)
   
 * Fixes in the EMSCB tarball:
   * Fixed C++ compatibility of libio interface:
     adapted packages: dde_linux, dde_linux26
   * Minor fixes in lxfuxlibc and l4vfs packages
