- change to always use the SG create mipmap function as it works better (no purple clouds)
- when enabled always generate a mipmap even if the file couldn't be compressed
- adjust level of log messages
- move lru_cache into its own header file.
The following changes fixes a case for me where I hear the sound change levels up and down for each pause un-pause cycle.

Effect schemes are a way of rendering an object in different ways depending on the Compositor pipeline. A new <scheme> tag in the Compositor pipeline definition allows the user to choose which Effect scheme is going to be used for that pass. Every Effect will then be rendered using the technique that has a matching scheme name. If no valid technique is found, it won't be rendered. Since it would be a pain to define a valid technique for every scheme and for every Effect, the file '$FG_ROOT/Effects/schemes.xml' is introduced:
<scheme>
<name>test</name>
<fallback>Effects/test</fallback>
</scheme>
If an Effect doesn't have a valid technique for the 'test' scheme, the 'Effects/test.eff' Effect will be merged with it. This process is done at initialization when techniques are being realized.
Previously, these two files were only added when SG was built with
-DUSE_AEONWAVE:BOOL=OFF, because the SG code in use when USE_AEONWAVE is
set to ON doesn't need readwav.hxx nor readwav.cxx. However, readwav.hxx
and readwav.cxx are not only used in SG, but also in FG (at least by
flightgear/src/Sound/VoiceSynthesizer.cxx), and this was causing a build
failure when SG's USE_AEONWAVE and FG's ENABLE_FLITE flags were both set
to ON:
https://forum.flightgear.org/viewtopic.php?f=45&t=35672#p346633
and
https://sourceforge.net/p/flightgear/mailman/message/36645567/
This commit should fix this build failure.
- remove the old svn properties; a scan of FGAddon and FGdata showed these are not in use except for the dialog
- new property "active" - which is true when the worker thread is running.
- changes to enabled now take effect immediately; whereas before a reinit had to be issued. This could lead to confusing GUI state as the enabled property would be true but without closing the dialog (e.g. cancelling it) terrasync could be in a different state.
- use property nodes (performance optimisation)
Extend the command API to allow posting commands from arbitrary threads,
for deferred execution on the main thread. Additional pieces on the FG
side to follow shortly.
changed to use const char* rather than const std::string & as this doesn't work on GCC; and besides std::string converts nicely to const char* and most of the times this is used it is actually a string literal.
Set the filename back to what it was after loading - seems sensible and as yet no side effects.
Also the previous commit that included the handling of sgio_exceptions also broke the DDS-TC pretty much completely.
