botan update to 1.10

[Thomas Moschny]

Hi,

this is a heads-up that I updated the botan package to the latest
stable version 1.10.5 in rawhide, as requested in bug 822421.

This changes the API and thus the soname of the library. Also, since
1.9.18, the library and header paths have been changed to allow
parallel installation of different versions of the library, so headers
are in /usr/include/botan-1.10/botan now, the library is named
libbotan-1.10, botan-config and the botan pkg-config file are
namespaced.

The dependent packages that need to be rebuilt by their owners are:

* bind10: configure finds botan-1.10, but a local rebuild failed
  later due to an unrelated problem as far as I can see

* softhsm: seems to support botan-1.10 in principle, but needs a
  patch for configure (resp. m4/acx_botan.m4) from SVN

* ne7ssh: rebuild failed, seems to need a patch

* monotone: needs a patch from mainline, will take care of that myself

Regards,
Thomas
