IMAP: downloading mails is now working.

* Changed the way the attributes are written to make sure that everything
that can be written once is in fact written just once.
* The rename code in BMailProtocol::_ProcessFetchedHeader() was broken,
and caused the hang of the last commit.

Mail Kit: Changed how filter changes work.

* BMailFilter::HeaderFetched() now only alters the entry_ref, and returns
B_MOVE_MAIL_ACTION to move a mail.
* Instead of potentially moving the file around several times, the
BMailProtocol now takes care of carrying out the filter action just once,
including trying to make the file name unique.
* This also allows the IMAP add-on to know the final location of the mail,
and thus downloading a message actually works.
* However, with my test inbox, it currently hangs, and a current Debugger does
not work on my older system -- I guess I need to update.
* Replaced the duplicated space mechanism within the "HaikuMailFormatFilter"
that is substantially faster, and handles all whitespace, not just spaces.
It will also replace tabs with spaces.

Work in progress of mail rework.

* Not everything compiles; all protocols, and inbound filters do, though.
* Renamed a few classes to give a better idea what they are for; prefixed
public classes with the 'B' prefix.
* Moved ProtocolConfigView's classes into the BPrivate namespace.
* Moved BMailFilter into its own file.
* Added BMailFilter::DescriptiveName(). This is now used by the RuleFilter
in order to give a description of what it's doing (ie. no more dozens of
"Rule filter" entries in the preferences).
* Removed no longer used MailAddon.h.
* Renamed Addon to AddOn where found, since that is more consistent with the
rest of the API.
* Merged the former MailProtocol with the former MailProtocolThread; the
differentiation between those two was pretty messy.
* All configuration views touched so far are now using the layout kit.
* The RuleFilter is currently broken functionality wise; I have not yet decided
how to solve the stuff it uses (TriggerFileMove() does not exist anymore,
for example).
* BMailAddOnSettings (formerly known as AddonSettings) now directly subclass
BMessage; there are no Settings() and EditSettings() method anymore. The
class uses a copy of itself to determine whether or not it has been changed.
* Lots of cleanup.

* Removed default_sent_directory(), and introduced
default_mail{_in|_out}_directory() methods in the BPrivate namespace.
* Used these methods in the inbound/outbound protocols.
* Moved WriteMessageFile() into the BPrivate namespace as well, and put its
prototype into a new header MailPrivate.h along with the new directory
getters.
* Removed the automatic copy to the sent directory again, and only have one
directory for incoming mail. Incidentally, this fixed #7509, although the
underlying filter restriction remains.
* Automatic whitespace cleanups, some style cleanups. Sorry for the mess.

Write MAIL:name, MAIL:thread and MAIL:account attribute. The account id is now stored in MAIL:account_id. This requires to re-download all mails to write the correct attribute (sorry).
Fixes #7375.



git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@41062 a95241bf-73f2-0310-859d-f6bbb57e9c96

Major restructuring of the mail server:

Accounts are now stored in a separate file. Previously they where somehow magically assembled from the chain ids. Now its possible to remove a account temporary by removing the account file form the account folder.

Each account could have an inbound protocol, an outbound protocol and some filters.

Mails are now associated with an account and not with a chain. This required to replace the chain id attribute by an account attribute.

Replace BMailFilter and BMailChain by a less general approach. Basically the chain had a list of filters and call the ProcessMailMessage for each filter. This made it sometime difficult to understand what is going on, e.g. sometimes a filter used information gathered by another filters. The new MailProtocol and MailFilter classes are calling more dedicated hook functions, e.g. HeaderFetched or MessageReadyToSend.

As before all MailProtocol's (plus their filters) are running in their own thread.

Cleaned up the error and status window a bit. Abstracted the interface to these windows. Should be easy to write a BNotification api back-end now.

Parsing of mail headers is much faster now. Fetching the headers of a large mailbox takes ~min and not ~hour now! Initial checkout time is in the same order like Opera. The problem was the massive use of fgets in parse_header (mail_util.cpp) now the complete header is read in one go. Furthermore, only interesting fields are extracted.

Remove some unused files, BeOS relicts... Feel free to translate the mail server and remove the own language system (headers/private/mail/MDRLanguage.h).

Sorry for the remaining old (and new) coding style issues, sometime just ignore them, to many :(
