Icecream 1.4rc1

[Lubos Lunak]

Hello,

I've tagged 1.4rc1 and will release a final 1.4 in some time if there are no
problems. There haven't been any code changes to Icemon, so it stays at
version 3.3.

From the NEWS file:
1.4
- scheduler assigns jobs with larger priority first, so compilations with
higher 'nice' value do not interfere with normal compilations
- avoid large timeouts if there is a network problem
- support for -march/-mcpu/-mtune used with =native (proper specific flags
will be substituted)
- support for Clang's -fmodules, by removing the -fmodules flag for remote
compilation
- do not keep host lock when sending preprocessed source (reduces chance of
network timeouts)
- send more jobs in advance to nodes with many CPU cores
- try to use larger network buffers
- force local compilations if --coverage is used
- correctly clean up caches
- handle properly the case when something removes files in the cache directory
