Subject: [PATCH] lib: Add dovecot_build_info variable containing Dovecot build
 information.

By default this includes the version, including the git hash. The idea is
that this version information would be available in all the core dumps.

The DOVECOT_BUILD_INFO can be overridden by compiling with:

DOVECOT_BUILD_INFO='"build info"' make
