The extensions listed in this setting do not need to be enabled explicitly using the Sieve require command.
This behavior voilates the standard, but is necessary for compatibility with some existing implementations of Sieve.
Do not use this setting unless you really need to!

Fixed a few printf format problems in the process.
Updated test suite to account for the new number width.

lib-sieve: code: Made jump offset code generation a bit more robust against integer overflow mishaps.

The actual version numbers live only on the release-branches from now on.

Mimics similar change in Dovecot.

Also made sure that any capability-derived state information is reset properly before a new capability reply is to be parsed.

lib-sieve: multiscript: Fixed bug in handling of (implicit) keep; final keep action was executed as though there was a failure.
Among other things, this caused the keep action to revert back to the initial message, causing editheader actions to be ignored.

Addresses LLVM scan-build report.

lib-sieve: storage: Local variable in sieve_storage_active_script_is_default() wasn't always properly initialized.
This was a LLVM scan-build report.

lib-sieve: imap4flags extension: Similar problem as previous commit, but relating to retrieval rather than manipulation.

Flags weren't always assigned properly, because the internal variable was not retrieved correctly.

lib-sieve: imap4flags extension: Forgot to check for empty flag/keyword in new flag checking function.

Added support for getting message part information and content.

Prevents useless jumps after break operation.

lib-sieve: Added support for having multiple instances of a single tag (type) within a single command.
