The limit is arbitrary.

We have well over one thousand configuration items, not counting
dummy hint entries. So now, sort all of them once (well, twice),
and use binary instead of linear search for lookups.
config_Get*, config_Put*, var_Create(with INHERIT flag),
var_CreateGet* and var_Inherit* do such lookups.

While string configuration items have been protected for a while, float
and integer items weren't. This is now fixed.

There is still a small bug in some plugins setting ->b_dirty without
locking the configuration lock for writing.

Previously, we had one configuration mutex per module.
With a global read/write lock, resetting, loading, saving and
auto-saving the configuration becomes atomic (and use only one lock &
unlock pair). Also, multiple threads can now read the configuration
item of the same module at the same time.

Note that, as the earlier configuration mutex, only configuration item
values are protected. The list of items and their meta-data cannot
change while VLC runs (they're hard-coded in the plugin descriptors).

That would return the PO file metadatas.

Loading the configuration from vlcrc or resetting the configuration does
not alter the command line parameter anymore.

The module bank is now locale-independent, so this was a waste fo time.
