dsync: Add hashed_headers setting This makes it possible to configure them

dsync: Try to commit transactions every dsync_commit_msgs_interval messages This was first attempted to be implemented by ec0cc8fa647794e44a1afaa448f495a713048dc4, but it was later partially reverted by 5973d496b16721af6d2c1fa90b016aacddf13554. This current commit should fix its problems.

doveadm: add doveadm_http_rawlog_dir setting

dsync: Add support for features Add empty_header_workaround as first feature

doveadm-auth: If auth_debug setting is enabled, send "debug" field to auth lookups. The idea is that you could enable auth_debug for specific requests with e.g.: doveadm -o auth_debug=yes user user@example.com

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

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.

doveadm: Added doveadm_username to specify the username for authentication. The default is still "doveadm" and the server side doesn't currently support anything except "doveadm".

doveadm director move/map: Use director_username_hash setting for calculating hashes.

doveadm auth/user: Fixes to auth_socket_path handling. doveadm user (without -u parameter) was ignoring "-a" parameter entirely. Others weren't using auth_socket_path setting.

Added ssl_client_ca_file to specify the CA certs as a file instead of as a dir. This is required for Redhat-based systems where there isn't a CA directory like in Debian/Ubuntu.

Moved lib-fs/fs-test to "doveadm fs" command.

Moved ssl_client_ca_dir and ssl_crypto_device to mail_storage_settings. Probably could also be moved to master_service_settings, but that makes accessing them a bit more tricky with the current code.

dsync: Added tcps (TCP+SSL) target.

doveadm: Renamed doveadm_proxy_port setting to doveadm_port. There's still an alias for doveadm_proxy_port.

doveadm: Added exec command to easily execute commands from libexec_dir. For example: doveadm exec imap -u user@domain

Made PKG_STATEDIR configurable with state_dir setting. Based on patch by Chris Webb. Normally this isn't needed, since the data in the state_dir can be shared across multiple Dovecot instances, but in some specific use cases this may be useful (e.g. users running their own Dovecots).

Array API changed: ARRAY_DEFINE(name, type) -> ARRAY(type) name Easy way to update your existing code: perl -i -pe 's:ARRAY_DEFINE\(([^,]+), *([^)]+)\);:ARRAY($2) $1;:' **/*.[ch]

dsync: Added dsync_remote_cmd setting, which is used to execute remote dsync. This is used for the old style "host" and "mailuser@host" parameters, as well as for a new "remote:[user@]host" parameter.

Merged dsync into "doveadm dsync". dsync symlink is installed for backwards compatibility.

doveadm: Added doveadm_allowed_commands setting, which is used by doveadm server.

doveadm: Added simple PLAIN authentication for remote connections. Currently clients are required to use "doveadm" as the username and the password must match doveadm_password setting. When using doveadm as a client, it automatically uses these settings when connecting to remote servers.

doveadm: Added doveadm_proxy_port setting to make it work with proxying.

doveadm: Moved -s parameter among -u/-A parameters, since it's only used by mail commands.

doveadm: Added client/server architecture support for running mail commands. This is done when doveadm_worker_count is non-zero.

doveadm: mail commands can now be extended more easily by plugins. Also plugins can now override the list of -A users. --HG-- branch : HEAD

doveadm: Look up sockets from base_dir rather than hardcoded PKG_RUNDIR. --HG-- branch : HEAD

doveadm: Added support for plugins. --HG-- branch : HEAD
