[Julian Andres Klode]

** Description changed:

- Line buffers are 1000 bytes and can be truncated; the cache database
- keys are truncated to 600 bytes, potentially causing growing databases.
+ [Impact]
+ Various static buffer lengths cause silent truncation of cache data or incorrect skipping of override lists:

+ Line buffers are 1000 bytes and can be truncated; the cache database keys are truncated to 600 bytes, potentially causing growing databases.
+ 
+ [Test plan]
+ Artificial test plans are included in the regression test suite run by autopkgtest.
+ 
+ [Where problems could occur]
+ In apt-ftparchive with long overrides or long file paths.
