lib: Added module_dir_try_load_missing() that returns error instead of logging it. Also module_names now can be given for it without i_fatal() being called.

liblib: Added module_dir_find()

Plugin ABI version checking improvements. Previously the plugin version was checked against the version string returned by the currently running Dovecot master process, not necessarily the same as the binary. Also version_ignore=yes setting skipped the version check entirely. Now there's a new DOVECOT_ABI_VERSION macro that can (at least in theory) be updated only when the ABI actually changes. The version is in format "2.2.ABIv1(2.2.15)", where the (2.2.15) would be the actual Dovecot version number that gets ignored when comparing the strings. Also now the plugin version is compared to the actually running binary's ABI, not the master's version, and it can't be ignored with a setting.

Marked functions parameters that are allowed to be NULL. Some APIs were also changed. The non-obvious APIs where NULL parameter was changed to "" are master_service_init() and auth_master_user_list_init(). These checks can currently be enabled only on a patched clang: http://llvm.org/bugs/show_bug.cgi?id=6786

module_dir_load*(): Support filtering and ignoring missing modules.

If module can't be loaded due to missing dependency, suggest a setting how to do it.

module_dir_load(): Added support for checking binary name dependency. --HG-- branch : HEAD

module_dir_load*(): Added ignore_dlopen_errors flag. --HG-- branch : HEAD

module_dir_load*() API changed to take settings struct, with debug field. Fixed debug logging to also go from info log to debug log. --HG-- branch : HEAD

Added module_dir_load_missing() and module_get_plugin_name(). --HG-- branch : HEAD

lib-storage: Plugin hook API changed to support per-user plugins within a process. --HG-- branch : HEAD

Added module_get_symbol_quiet(). --HG-- branch : HEAD

Changed .h ifdef/defines to use <NAME>_H format. --HG-- branch : HEAD

Don't compare to PACKAGE_VERSION in lib/ core directly, rather make module_dir_load() have the version string as parameter. Plugin version checks can be skipped with version_ignore=yes. --HG-- branch : HEAD

module_dir_load() doesn't call init() functions anymore. Added a new module_dir_init() which does it. This way imap/pop3 can load the modules before chrooting and initialize them after. --HG-- branch : HEAD

Allow giving module names in non-basename form. --HG-- branch : HEAD

Replaced mail_use_modules and mail_modules settings with mail_plugins and mail_plugin_dir. Now instead of loading all plugins from the directory, you'll have to give a list of plugins to load. If the plugin couldn't be loaded, the process exits instead of just ignoring the problem (this is important with ACL plugin). --HG-- branch : HEAD

Added module_dir_deinit(). --HG-- branch : HEAD

deinit, unref, destroy, close, free, etc. functions now take a pointer to their data pointer, and set it to NULL. This makes double-frees less likely to cause security holes. --HG-- branch : HEAD

Added "bool" type and changed all ints that were used as booleans to bool. --HG-- branch : HEAD

Added support for password scheme plugins. auth module dir defaults under module_dir now. --HG-- branch : HEAD

missing --HG-- branch : HEAD
