These libraries are bound for E-D-S so they live at the lowest layer of
Evolution for now -- even libeutil can link to them (but please don't).
This is the first step toward moving mail handing to a D-Bus service.
More mail API churn... reversing some previous API decisions.
I've made some key API changes to EMailSession on the account-mgmt
branch which should allow for this, and will hopefully also benefit
the "email-factory" branch.
EMailBackend barely needs to exist anymore, except as the owner of
EMailSession.
For several low-level functions, we replace its EMailBackend parameter
with EMailSession and EAlertSink parameters; the latter so it can still
pass user alerts up the chain.
This implements https://bugzilla.gnome.org/show_bug.cgi?id=663527#c3.
Account reordering is now done by drag-and-drop instead of up/down
buttons.
Turned out to be a wee bit more complicated than I initially thought.
This scraps EAccountManager and EAccountTreeView and replaces them with
new classes centered around EMailAccountStore, which EMailSession owns.
EMailAccountStore is the model behind the account list in Preferences.
The folder tree model now uses it to sort its own top-level rows using
gtk_tree_path_compare(). It also broadcasts account operations through
signals so we don't have to rely so heavily on EAccountList signals,
since EAccountList is going away soon.
Also as part of this work, the e-mail-local.h and e-mail-store.h APIs
have been merged into EMailSession and MailFolderCache.
Also set the disposition field according to user preferences.
If the MDN is sent without user confirmation ("always"), use:
Disposition: automatic-action/MDN-sent-automatically;displayed
If the MDN is sent in response to user confirmation ("ask"), use:
Disposition: manual-action/MDN-sent-manually;displayed
