Use AccountManager for POP/IMAP; refactor setup classes
There are two major, interrelated parts to this CL:
1) Clean up the activities to reduce the use of Intents to pass
information between activities; instead, we use a common
SetupData structure that automatically saved/restored as necessary
during the setup flow. A fair amount of code and inconsistent
use of Bundle extras has been eliminated in the process.
* Create SetupData structure, setters/getters, and initialization
methods to simplify the preservation of state during setup flow
* Remove all state/flow extras from Intents; Intents now only
specify the Activity to be started, which should greatly simplify
the transition to Fragments.
* Remove all state/flow fields from Activities
* Modify existing setup activity unit tests and confirm tests pass
2) Create AccountManager accounts for POP/IMAP email accounts to
provide consistency in user experience. Also, internal flows are
now identical as between account types.
* Move account reconciliation from SyncManager to MailService, so
that reconciliation is consistent between email and exchange
accounts; move unit tests as appropriate
* Add a "Sync Email" setting for POP/IMAP/EAS
* Change MailService to respect the "Sync Email" setting in
Settings -> Accounts & sync
* Create PopImapSyncAdapterService to handle manual POP/IMAP sync as
requested by SyncManager; add EmailSyncAdapterService to perform
the same function for EAS
* Use new PopImapAuthenticatorService to add AccountManager accounts
for POP/IMAP accounts; setup appropriate stanzas in AndroidManifest
and add related xml files
* Update AccountSettings to use SetupData
Miscellaneous other changes:
* Only allow valid port numbers in incoming/outgoing setup
