- Enable building of the qt_mutex module. This means that from now
  on libbotan requires libQtCore.
- Fix test for thread/mutex support to also work for Qt4.
- Update to 1.8.10:
  * This release changes a number of aspects of how private keys are
    encrypted. The default encryption algorithm has changed from 3DES
    to AES-256
  * The default iteration count for PBES1 and PBES2 encryption schemes
    (which are used primarily to encrypt asymmetric keys like RSA or
    DSA) has increased from 2048 to 10000, which should make brute
    force key cracking substantially harder.
  * The first round of AES now uses a smaller set of lookup tables;
    this only reduces performance slightly but some timing and cache
    analysis attacks against AES are substantially harder when AES is
    implemented this way.
  * The class known as S2K was renamed PBKDF in 1.9, with a typedef
    for backwards compatibility. For providing an equivalent forward
    compatibility path, 1.8.10 includes a typedef for PBKDF and a new
    accessor function get_pbkdf. It also includes a new interface for
    deriving keys with a passphrase which takes both the passphrase
    and desired output length as well as the salt and iteration
    count; in many cases this call is actually significantly more
    convenient than the older API.
