Follow-up to the feature that allows skipping certain ADGF flags.
This here now also allows skipping of incomplete file/md5/size matches. It is basically the same behavior as the graylist. For the mass add all files are treated as if they are on the list.
I added skipping for the ADGF_WARNING and ADGF_UNSUPPORTED flags.
For me, this is mostly about fixing bug no. 13282. We sometimes have bogus entries which only have the purpose of presenting the error message (reasons for being unsupported) contained in the extra field of the detection entry.
Fixes assigning the wrong game id when upgrading a target to have
an engine id. If a game had been run earlier ran then its checksums
could still be cached. If both games were from the same engine then
advanced detector could select the previous game.
Fixes bug: #13458
Trying all engine plugins in alphabetical order is a time consuming
process, so start by trying the plugin which has the same name as the
engine id first, if it exists, as it will usually be the right one.
In the rare case that it would be the wrong one there is no problem;
the code will simply fall through to the old scanning and then record
the correct plugin in the engine_plugin_files domain where it will be
found the next time the plugin is needed.
Plugin filenames are all upper case on Dreamcast due to the ISO 9660
filesystem. It doesn't seem likely that making the check case
insensitive would cause any problems even on a file system that
is case sensitive.
This is a degradation from the split of detection plugins. All the
caching code which was present was left with detection plugins which
now make no sense: we always load all detection plugins as a whole.
This commit moves the caching logic over to the Engine plugins.
This opens a question now whether we should move all to UNCACHED_PLUGINS
Making it hardcoded because:
* This is the only place where it could happen
* It is the second time in history of ScummVM when we renamed
and engine (the first one was Simon -> AGOS)
Thus, there is a little sense in creating a universal solution.
