6865fad5c7 New caching provider using APC's shared memory cache.
Used now by default, if function apc_fetch() exists and no
other caching provide is explicitly set in header.inc.php or egw_cache
class. 
It's probably quicker on virtual machines, as it uses memory and not the
filesystem.

3ec3c205ee created a rpm post script to automatic install or update EGroupware:
- cleaned up exceptions in cli code (no need to log, as it goes direct to the user)
- regarding small rpm redirect header (< 200 bytes) as no header
- fixed wrong detected vars for cli install (eg. webserver_url)
- fixed egw_cache to not stall if system_charset is not yet in db

bf036043b2 - making all methods of translation class static
- caching the phrases in new egw_cache on Tree level
--> a good speed improvment on my devel system
- also added a global function
check_load_extension($extension,$throw=false)

fd9856ebf5 Class to manage caching in eGroupware:
It allows to cache on 4 levels:
a) tree:     for all instances/domains runining on a certain source path
b) instance: for all sessions on a given instance
c) session:  for all requests of a session, same as egw_session::appsession()
d) request:  just for this request (same as using a static variable)

There's a get, a set and a unset method for each level: eg. getTree()
or setInstance(), as well as a variant allowing to specify the level as first
parameter: eg. unsetCache()

getXXX($app,$location,$callback=null,array $callback_params,$expiration=0)
has three optional parameters allowing to specify:
3. a callback if requested data is not yes stored. In that case the
   callback is called and it's value is stored in the cache AND retured
4. parameters to pass to the callback as array, see call_user_func_array
5. an expiration time in seconds to specify how long data should be cached,
   default 0 means infinit (this time is not garantied and not
   supported for all levels!)

Data is stored under an application name and a location, like
egw_session::appsession().
In fact data stored at cache level egw_cache::SESSION, is stored in
the same way as egw_session::appsession() so both methods can be used
with each other.

The $app parameter should be either the app or the class name, which
both are unique.

The tree and instance wide cache uses a certain provider class, to
store the data eg. in memcached or if there's nothing else configured
in the filesystem (eGW's temp_dir).
