There's currently a bug in linkifyText() that can lead to a
StringIndexOutOfBoundsException when the text contains a
bitcoin URI and a "web" URI near the end of the text.
Under certain circumstances it's possible that the 'push state' isn't
updated to contain the most recent 'UIDNEXT' value. In that case
ImapFolderPusher.start() would execute the same code path through its
main loop over and over again, preventing the device from going to
sleep.
Rather than changing the code to update the 'push state' in the corner
case that triggers the behavior described above, this commit introduces
another mechanism to track the 'UIDNEXT' value. This should also catch
as of yet unknown cases where the 'push state' isn't properly updated.
At some point in the future I hope we get to a point where we only
persist the 'push state' when we manually stop/restart the service.
During normal operation there's no need to read from/write to storage
all the time.

When message viewing and tap the next icon, menu icons (previous, next, delete and replys) disappears for an instant.
But a compose icon remains, then tap it accidentally.
Eliminate the invocation of
WebSettings.setBlockNetworkImage(boolean flag),
thus maintaining the the default setting of "false".
On Android versions prior to KitKat, this setting has no
effect on inline image attachments loaded with content:
URIs. Such images would load regardless.
With KitKat, this setting does have an effect -- a
setting of "true" will block image attachments loaded
with content: URIs.
By removing this call, K-9 Mail behaves the same on KitKat
as on earlier Android versions, and the behavior on earlier
versions is unchanged.
The minSdkVersion was recently increased from 8 to 15.
WebSettings.setBlockNetworkLoads has been publicly available
since API level 8 (Froyo).
StrictMode has been publicly available since API level 9
(Gingerbread).
Also, include the sent-date in the header when using
the "prefix" quote style. "Be like mutt" (and gmail,
and thunderbird)
Also, the quoteOriginalHtmlMessage method was using the mSourceMessage
field in various places when it should be using its originalMessage
parameter.

There were a number of preferences that were not being removed
from the preferences DB when an account was deleted, so they
would remain there forever.
There were a few attempts to remove preference keys from the DB where
the keys were obsolete and not in use for some time.
Certain obsolete preferences were not modified:
mUuid + ".name"
mUuid + ".email"
mUuid + ".signature"
mUuid + ".signatureUse"
These were in use before implementing multiple identities, and are still used
as a fallback for old accounts without multiple identities configured.
The error reporting assures an exception is thrown if
setKeyStoreFile(null) is called without a prior call to
setKeyStoreLocation(String directory).
Also, fix TrustManagerFactoryTest indentation.
Blacklist a couple of weak ciphers, bring known ones in a defined order and sort unknown
ciphers at the end. Also re-enable SSLv3 because it's still used a lot.
Instead, have K9.onCreate initialize the location of the key
store file (similar to what is done with
BinaryTempFileBody.setTempDirectory).
Also, LocalKeyStore.getInstance has been changed so that it
no longer needs to be synchronized.
Implement an "upgrade" capability for the key store file,
and then use it to delete the old file.
The existing certs in the old file are not a security
risk, but they are now useless because the format of
their aliases was changed in commit a4440b4. They now are
just taking up storage space and memory.
Users will need to re-accept *ALL* certificates that they had
previously accepted and are still using. (Actually, this requirement
was effective with commit 4b57d79a. Before that, certificates whose
Subject matched did not require re-accepting.)
The classes are just as much related to com.fsck.k9.mail.transport
as com.fsck.k9.mail.store, so having them in
com.fsck.k9.mail.store doesn't seem appropriate.
Move LocalKeyStore to com.fsck.k9.security
Move TrustManagerFactory and TrustedSocketFactory to com.fsck.k9.net.ssl
Also, implement the ability to configure an alternate key store
file location. This permits the running of unit tests without
clobbering the live key store file.
Also, add a test to confirm that the key store file is being written
out and reread correctly.
Proper host name validation was not being performed for certificates
kept in the local keystore. If an attacker could convince a user to
accept and store an attacker's certificate, then that certificate
could be used for MITM attacks, giving the attacker access to all
connections to all servers in all accounts in K-9.
This commit changes how the certificates are stored. Previously, an
entire certificate chain was stored for a server (and any of those
certificates in the chain were available for validating signatures on
certificates received when connecting). Now just the single
certificate for the server is stored.
This commit changes how locally stored certificates are retrieved.
They can only be retrieved using the host:port that the user
configured for the server.
This also fixes issue 1326. Users can now use different certificates
for different servers on the same host (listening to different ports).
The above changes mean that users might have to re-accept certificates
that they had previously accepted and are still using (but only if the
certificate's Subject doesn't match the host that they are connecting
to).
This commit modifies AccountSetupBasics so that it now calls
AccountSetupCheckSettings twice -- once for checking the incoming
settings and once for the outgoing settings. Otherwise, an exception
could occur while checking incoming settings, the user could say
continue (or the user could accept a certificate key), and the
outgoing settings would not be checked. This also helps with
determining if a certificate exception was for the incoming or
outgoing server, which is needed if the user decides to add the
certificate to the keystore.
The TrustedSocketFactory, which provides goodies like better cipher suites and
TLSv1.2, was only being used for tunnelled connections. Use it for STARTTLS
connections as well.
