Makefile: Fixed building fts-squat

Makefile: Fixed test program dependencies Explicit dependencies on .o or .lo files didn't seem to work properly and with high enough make -j value the build failed. Depending on the entire library guarantees that all the individual .o files have been built.

Makefile: Link with SSL_LIBS whenever linking libssl_iostream.la

Use -Wl,--as-needed -Wl,--no-undefined GNU ld flags for non-plugins.

Added dovecot.m4 file that external plugins can use. Based on patch by Dennis Schridde. --HG-- branch : HEAD

OSX: Don't try add plugin dependencies. It just breaks plugin loading. --HG-- branch : HEAD

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

plugins: Added dependencies. The dependencies can only be checked if the dlopen() can successfully open the module, so use (apparently) non-portable ltlibrary linking to force the libraries we depend on to load with us. --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

Get rid of imap/, pop3/, lda/ and sql/ module subdirs. It's all in lib/dovecot/ now. --HG-- branch : HEAD

Removed LIBICONV from unnecessary places. --HG-- branch : HEAD

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

$STORAGE_LIBS now contains all the libraries that libstorage needs. There's no point in listing the same required libraries everywhere. --HG-- branch : HEAD

shared namespaces: new %%h variable, expanding to the traget users home. --HG-- branch : HEAD

Symlink FTS plugins to pop3 directory too. --HG-- branch : HEAD

Previous changes broke plugin symlink creation in make install. --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

Use dynamic module suffix provided by libtool rather than hardcoded ".so". --HG-- branch : HEAD

Changed library linking order. --HG-- branch : HEAD

Better type safety to module_contexts arrays. Already fixed some bugs. --HG-- branch : HEAD

Added missing .h file --HG-- branch : HEAD

Changed the plugin filename numbering (ie. the ordering in which the plugins are loaded). This doesn't change anything for current plugins, but future plugins will need this change so they can get themselves loaded between specific plugins. --HG-- branch : HEAD

Added "squat" full text search indexer backend. Its name and basic ideas originate to Cyrus's squat index, but Dovecot's implementation is completely different and it supports incremental updates. Still a bit broken and lacks locking, but I wanted to get this into CVS now. --HG-- branch : HEAD
