[fdo-internals] Provider registry...

[Jason Birch]

Hi all,

The current providers.xml method of storing the provider list works
fairly well, but it makes it difficult and error-prone when users are
installing new providers that are not distributed with their FDO build.

Does anyone else see value in switching to a method that picks up all
files that follow a certain pattern and adds them to the registry?

Like:

providers.xml
providers.postgis.xml
providers.sqlite.xml

This would allow the old method (everything in one file) to continue to
work, but would also allow bundling specific providers that plug in by
just copying files into the fdo bin directory.
