lib-dict: Move libdict_backend to lib-dict-backend

Add PIE and RELRO to binaries

dict: Show command statistics in process title.

MODULE_LIBS is now part of LIBDOVECOT. No need to explicitly link it everywhere.

Makefiles: Separated LIBDOVECOT and LIBDOVECOT_DEPS. --HG-- branch : HEAD

dict proxy: Use base_dir as the default dict-server location. --HG-- branch : HEAD

Removed unnecessary macro definitions from Makefiles. --HG-- branch : HEAD

dict server works again. --HG-- branch : HEAD

Moved most of the dict settings handling to dict binary. --HG-- branch : HEAD

Some binaries were missing list of library dependencies. --HG-- branch : HEAD

Added configure --without-shared-libs to link built binaries against static libraries. The libraries are still built and installed, so this is mainly useful for making life easier for developers. --HG-- branch : HEAD

Link -liconv to libdovecot.so if necessary. --HG-- branch : HEAD

Build libdovecot.so and libdovecot-storage.so. Based on patch by Stephan Bosch. --HG-- branch : HEAD

dict sql: Added configuration for mapping dict paths to SQL fields. --HG-- branch : HEAD

If we need -lcrypto for randomness, put it to $LIBS instead of $RAND_LIBS since it needs to be linked to all binaries anyway. --HG-- branch : HEAD

Create a separate libdict_backend.a library with sql/db backends and link it only to dict server. This fixes linking issues with linkers that didn't automatically drop the unused sql/db code. --HG-- branch : HEAD

Use dicts directly instead of caching them. Caching doesn't help much here. --HG-- branch : HEAD

Load plugins from $moduledir/dict/. --HG-- branch : HEAD

Berkeley DB dict support is now enabled only when using --with-db configure option. --HG-- branch : HEAD

Added -export-dynamic. --HG-- branch : HEAD

Added RAND_LIBS --HG-- branch : HEAD

Dictionary takes now a username parameter, which is used for private queries. Made dict-sql use "insert .. on duplicate key update" syntax, which unfortunately doesn't work with PostgreSQL yet. --HG-- branch : HEAD

Compile fix --HG-- branch : HEAD

Added dictinary lookup server and a "proxy" dict implementation to talk to it. --HG-- branch : HEAD
