Add generated files for OO API for C language to distribution
GitHub Issue: 8197 Apply to: 5.0.2, 6.0 Alpha 1
There are many programs written in C. At the moment they use the legacy isc API. But at the moment the isc API is not being developed and it is impossible to add new functionality to such programs. I know that with the help of CLOOP we can generate an OO API for the C language. But most developers are not aware of this. Moreover, they are afraid if some generated C interfaces get into their program, which over time can change in FB and they will become broken.
Cardinality estimation should use primary record versions only

New feature/improvement requests
Allow firebird.log location to be set from config or environment variable
GitHub Issue: 8246
It would be helpful to be able to configure the location of firebird.log from an environment variable, or from the config file, or both. Currently it can only be configured at compile time.
Our use case: we ship Firebird as the embedded database in our application. The files are installed in Program Files which is not writable by the users running the application, so no logging is possible. We'd like to set it via environment variable to a path in the user's profile which will be writable.
