By default, when java converts Strings to bytes, it uses the
default system locale. This can be specified by the -Dfile.encoding
option. If no file encoding is specified, java uses ISO8859_1.
Unfortunately, not all unicode characters can be mapped to
ISO8859_1. Unmappable characters may be replaced by a byte
within ISO8859_1, which may change the meaning of the String.
This is especially problematic for password strings, and has
been used to compromise the security of passwords in the
past.
Thankfully, Android uses UTF-8 by default, so this bug doesn't
effect Android devices. However, it's recommended to explicitly
list the character set when converting to/from bytes to
avoid the potential ambiguity.

Since we need to test the keystore with user system in order to test
the reset(), password(), lock() and unlock(), we have to take advantage
of the ActivityUnitTestCase to run the test with the user 'system'.
* Refactor netkeystore.c to make client and server code testable.
* Add a client test for setting new passwd and changing passwd.
* Exclude "." and ".." from reset_keystore().
* Change ServerCommand.executeCommand() to accept variable length of
arguments and add convert() to marshalling the args to bytes.
* Keystore.java is revised accordingly.
+ Use '\0' as the delimiter.
+ Allow whitespace character for keystore password.
In previous implementation, we use space as the delimiter. That
will stop user from using passphrase with whitespace character.
1. the certtool.h is modified for avoiding the side effect,
for saving the configuration with wpa_supplicant.
2. put the loadLibrary back in CertTool.java
3. Fix incorrect JNI declarations.
Keystore is reimplemented and it is mainly for storing
(key, value) pair generically. The certificate related
APIs are moved to the class CertTool instead.
Updates:
Provide the getInstance() which gives the singleton.
Fix the missing construction of the BIO in cert.c.
1. Also change the keyname delimiter in CertTool.java.
2. Return NOTFOUND if the result.len==0 in the listKeys().
3. Define the keystore states in the class Keystore.
1. Have the new Keystore for mini-keystore impelemntation.
2. Add CertTool library and jni dll for handling keygen and certificates.
3. Make Reply hidden.
4. Revert some 'incorrect' change and correct the description.
