doveadm: Add new "stats dump" command

global: Renamed stats plugin and service to old-stats

global: Rename client_connection_type to doveadm_connection_type

doveadm: Rename client_connection_type to doveadm_client_connection_type Move it to doveadm.h to allow plugins use doveadm-cmd.h

doveadm: Changed command contexts to contain the input, output, and connection type values directly. Before, it used a direct pointer to the connection. It used also flags to indicate the connection type, which is now consolidated in the connection type enum.

Added "doveadm process status" This allows asking for processes' current status in master process.

Added "doveadm service status" This allows asking for services' current status in master process.

doveadm: Fixed -A and -u wildcard handling with server connections.

doveadm: Pass connection to mail context

doveadm: Added "service stop" command to stop specific services.

doveadm: Implement user and auth cache flush to server

doveadm-server: Skip doveadm_print_init Some commands need to do output that is not doable with doveadm_print, so we need to have a flag to indicate this.

doveadm-server: Fixed running multi-word commands. The problem with for example "mailbox status" command is that: - doveadm cli: argv[0] = "mailbox", argv[1] = "status" - doveadm-server: argv[0] = "mailbox status" So with doveadm cli we'll now instead just skip over words until argv[0] is the last word of the command ("status").

doveadm: Code cleanup - always use const char *const[] type for argv. Needed to fix compiler warnings in the following patch.

doveadm: A bit nicer way to implement doveadm_cmd_param_array() returning C-string array So replacement of 4afc67eb9, which I accidentally pushed before remembering about this other way.

doveadm-kick: Rewrite to ver2 infra

doveadm-who: Rewrite to ver2 infra

doveadm: Changed doveadm_cmd_param_array() to return C-string array instead of ARRAY() We could support both with separate functions, but perhaps this one is enough.

doveadm: Changed v2 command APIs to be easier to use.

doveadm: Add more consts to avoid a cast breaking strict-aliasing rules.

doveadm: Pass through mail_storage_service_input fields in doveadm_cmd_attributes

doveadm: Added struct doveadm_cmd_attributes, which is passed around instead of argc/argv

doveadm-penalty: Convert to ver2 infra

doveadm: Code cleanup - coding style fixes for doveadm_cmd_param*() accessors

doveadm-cmd: Add CMD_PARAM_IP

doveadm: Remove return value from ver2 cmd() - doveadm_exit_code is enough

doveadm-cmd: Constify doveadm_cmd_param_*() usage

doveadm: Added doveadm_cmd_get_ver2() helper

doveadm-cmd: Add command flags

doveadm: Free istream parameters everywhere Based on patch by Aki Tuomi

doveadm: Minor code cleanup - rename doveadm_cmd_find*() to doveadm_cmd_find_with_args*()

doveadm-stats: Use ver2 structures

doveadm: Use char type for short options instead of a string. The ":" = "has parameters" can be determined from the type. Also removed "?" checks since it wasn't actually used.

doveadm: Remove CMD_PARAM_NONE type, since it already defaulted to same as CMD_PARAM_BOOL

doveadm: Use ver2 structures for stop & reload.

doveadm: Implement HTTP server API, slightly based on JMAP API

doveadm: Add infrastructure for doveadm_cmd_ver2 Version 2 commands have named parameters, which also have types. This is especially useful for reading input from HTTP/JSON API. This also simplifies the parameter parsing for command line input. For v2.3 the plan is to replace all the old doveadm_cmds with this new version and get rid of the _ver2 suffixes. But for now we'll have two versions of commands. For backwards compatibility with old commands we have also implemented wrappers so that v2 structs can be defined and there's a function to convert the named parameters to old v1 style args[] string, so the old command handlers can still be run. This will also be removed in v2.3. This change also adds requirement for getopt_long(). It's already available in all the Linuxes and BSDs, so this shouldn't be too big of a requirement. Other systems can install it from an external library.

doveadm-stats: Add stats reset command line

doveadm: Moved commands related code to doveadm-cmd.[ch] Commands are already split for command line-only commands and commands that can be run via doveadm-server also.
