lib-storage: Add mail_namespace_is_inbox_noinferiors()

lib-storage: Add struct mail_namespace.user_set

lib-storage: Add mail_namespace_alloc() This makes it easier to create new namespaces. Based on patch by Jeff Sipek

lib-storage: Clarify that mail_namespace_find_inbox() never returns NULL. If namespaces==NULL, this function isn't even supposed to be called.

global: unsigned int:1 -> bool:1 perl -i -pe 's/unsigned int ([^,:;]+):1;/bool $1:1;/' **/*.[ch]

lib-storage: Added mail_namespaces_init_add/finish() to manually initializing namespaces.

lib-storage: Added mail_namespace_is_shared_user_root() and used it where useful. Most importantly this should fix a crash in ACL plugin where type=shared namespace was used without any kind of per-user prefix/location (i.e. it probably should have been a type=public namespace instead).

lib-storage: Added support for multiple storages per namespace.

If prefix="" namespace isn't defined, autocreate it as an unusable namespace. This avoids having to handle mail_namespace_find() errors all over the place. Instead now the mailbox accesses will simply fail.

lib-storage: Use const pointers for mail_namespace.(set|unexpanded_set)

imap: Fixed LIST (SPECIAL-USE RECURSIVEMATCH) to actually return CHILDINFOs.

Renamed enum namespace_type to enum mail_namespace_type

lib-storage: If alias_for references inbox=yes namespace, copy the inbox=yes to the alias ns. So even though this still doesn't allow giving multiple inbox=yes settings in configuration file, it's now possible for multiple namespaces to have them. They just need to point to the exact same INBOX.

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

Moved mailbox {} settings inside namespace {} and no longer require ns prefix in name. This allows specifying mailboxes more easily with per-user namespace prefixes.

lib-storage: Added mail_namespace_find_unalias()

lib-storage: Added mail_namespaces_init_location() for creating a single namespace for user.

lib-storage: mailbox_alloc() now takes a virtual mailbox name and other related API changes. All storage_name <-> vname conversions now go through the same two mailbox_list methods. This has many benefits, such as: * listescape plugin is now much simpler and bugfree * allows changing lib-storage API to use UTF-8 mailbox names in future * allows creation of "mailbox aliases" plugin

lib-storage: Added refcounting support for namespaces

Fixes to INBOX sharing. NAMESPACE_FLAG_INBOX was split to two flags: _FLAG_INBOX_USER (this namespace has the user's own INBOX) and _FLAG_INBOX_ANY (namespace has INBOX, either user's own or another user's). --HG-- branch : HEAD

When creating shared directories, preserve parent dir's permissions if it has setgid bit enabled. This works only if location path uses %variables. The directories up to last variable are created by preserving parent directory's modes, while the rest of the directories are created with 0700. For example with "/var/mail/%d/%2n/%n/Maildir", "/var/mail/domain/nn" preserves /var/mail's permissions, while the "username/Maildir" directories have 0700 mode. --HG-- branch : HEAD

lib-storage: mailbox_list_iter_init_namespaces() has more filtering capabilities now. - namespace types - MAILBOX_LIST_ITER_STAR_WITHIN_NS flag so that "*" doesn't escape beyond the namespace it started in. --HG-- branch : HEAD

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

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

Initial commit for making mail_storage:mailbox_list to be from 1:1 to n:n. This will allow namespaces to share the same storage and a single namespace to have multiple storages (multiple mailbox formats). Neither works currently, and this commit probably breaks some things. --HG-- branch : HEAD

Split NAMESPACE_FLAG_INTERNAL into distinct _NOQUOTA and _NOACL flags. --HG-- branch : HEAD

acl: Don't try to create dovecot-acl-list file for unknown users' auto-created namespaces. --HG-- branch : HEAD

mail-storage API: Added some function description comments. --HG-- branch : HEAD

Fixed plugins to work with config rewrite. --HG-- branch : HEAD

Initial commit for config rewrite. --HG-- branch : HEAD

Added alias_for setting for namespaces. Fixes namespace issues with fts. --HG-- branch : HEAD

mail_user_*() now handles home directory lookups when necessary. Namespace owner is now a pointer to struct mail_user rather than a string. --HG-- branch : HEAD

Added namespace owner username to struct mail_namespace. --HG-- branch : HEAD

Added list=children option for namespaces. --HG-- branch : HEAD

When autocreating a new shared namespace, drop existing namespaces where we haven't seen any mailboxes. --HG-- branch : HEAD

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

Subscription handling fixes for subscriptions=no namespaces and shared mailboxes. --HG-- branch : HEAD

Removed pool parameter from mail_namespaces_init*(). Use mail_user's pool intead. --HG-- branch : HEAD

Added struct mail_user and fixed the code to support multiple users per process. --HG-- branch : HEAD

Added more consts, ATTR_CONSTs and ATTR_PUREs. --HG-- branch : HEAD

mail_storage_create() now finishes namespace initialization so namespaces can be created more easily. --HG-- branch : HEAD

Fixes to handling namespace prefixes and real!=virtual separator. Added a new MAILBOX_LIST_ITER_VIRTUAL_NAMES which specifies if mailbox listing should be using virtual or real mailbox names. --HG-- branch : HEAD

Added subscriptions setting to namespaces to specify if it should handle subscriptions itself or if the parent namespace should handle them. --HG-- branch : HEAD

Mark deliver's dummy mbox namespace as internal and don't include it in quota calculation. --HG-- branch : HEAD

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

Added hook_mail_namespaces_created. --HG-- branch : HEAD

Added mail_namespace_find_inbox() and mail_namespace_find_prefix_nosep() --HG-- branch : HEAD

Moved several namespace booleans to a flags field. Removed unused subscriptions boolean. --HG-- branch : HEAD

Store namespaces sorted by their prefix length. --HG-- branch : HEAD

Make sure all listable namespaces use the same separator. If there's no ref or "" namespace, use that separator instead of INBOX's. --HG-- branch : HEAD

Added list setting to namespaces to control whether mailboxes in the namespace are visible with LIST command without giving the namespace prefix (eg. does LIST "" * show the mailboxes or not) --HG-- branch : HEAD

Added mail_namespace_update_name() --HG-- branch : HEAD

Added mailbox_list to struct mail_namespace. Added a few functions to get private data out of mailbox_list. --HG-- branch : HEAD

Moved namespace handling to lib-storage. Beginnings of namespace support for non-IMAP parts of Dovecot. --HG-- branch : HEAD
