lib-settings: Added support for running checks after variable expansion.

lib-settings: Fix spelling of 'expanded'

lib-settings: Add settings_parse_keyvalue()

lib-settings: Avoid duplicating settings' values when not needed

lib: API change - var_expand*() now returns error string. This allows callers to fail properly if the format string is invalid.

lib-settings: Added SET_TIME_MSECS type.

lib-settings: Added settings_get_time_msecs()

Removed SET_IN_PORT_ZERO - SET_IN_PORT now always allows zeros as well. A zero in all the port settings means that the port is disabled, which is also the default. So it shouldn't be an error to explicitly set it to zero in the config file.

Earlier in_port_t fix created problems with service listener configuration. Listeners are disabled with port=0, which was not allowed anymore.

Changed type of internet port values to in_port_t everywhere. Created special SET_IN_PORT setting type for internet port values. Created net_str2port() for parsing internet port values. Removed several atoi() invocations in the process.

lib-settings: Added settings_var_expand_with_funcs()

lib-settings: settings_parser_apply_changes() now deduplicates SET_STRLIST arrays. This fixes overriding strlist keys in config file filters, e.g.: plugin { foo = general } protocol lda { plugin { foo = lda-specific setting } }

Fixed memory leak when parsing settings. --HG-- branch : HEAD

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

lib-settings: Added some consts to parameters. --HG-- branch : HEAD

config: $setting as value returns the setting's current value. --HG-- branch : HEAD

config: Added support for "octal integer", which is just printed as octal. --HG-- branch : HEAD

settings parser: Added support for setting name aliases. --HG-- branch : HEAD

lib-settings: settings_get_time/size() are now public. --HG-- branch : HEAD

Added "time" (interval) setting type, which supports s/m/h/d/w suffixes. --HG-- branch : HEAD

Added "size" setting type, which supports B/k/M/G/T suffixes. --HG-- branch : HEAD

Moved default service settings from master.conf to source code. --HG-- branch : HEAD

Changed all settings related structs to const and changed APIs to make it work. --HG-- branch : HEAD

config: Added SET_DEFLIST_UNIQUE type. Settings in unique sections can be overridden. --HG-- branch : HEAD

settings_find_dynamic() now takes const pointer. --HG-- branch : HEAD

lib-settings: Added settings_check() to check specific setting structure. --HG-- branch : HEAD

Binaries now take -o key=value parameters to override settings. --HG-- branch : HEAD

Initial commit for v2.0 master rewrite. Several features are still missing. --HG-- branch : HEAD

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

Added lib-master and mail-storage-service code that makes it easier to build new Dovecot binaries. Currently only the standalone applications (e.g. deliver) uses this. --HG-- branch : HEAD
