This update for clamav brings the 0.99.0 stable release and fixes the following issues:

- Update to version 0.99 (boo#957728)
* Processing of yara rules(some limitations- see signatures.pdf).
* Support in clamav logical signatures for many of the features
added for YARA, such as Perl Compatible Regular Expressions,
alternate strings, and YARA string attributes. See signatures.pdf
for full details.
* New and improved on-access scanning for linux. see the recent blog
post and clamdoc.pdf for details on the new on-access capabilities.
* A new clamav api callback function that is invoked when a virus
is found. This is intended primarily for applications running in
all-match mode. Any applications using all-match mode must use
the new callback function to record and report detected viruses.
* Configurable default password list to attempt zip file decryption.
* Tiff file support.
* Upgrade windows pthread library to 2.9.1.
* A new signature target type for designating signatures to run
against files with unknown file types.
* Improved fidelity of the "data loss prevention" heuristic
algorithm. Code supplied by Bill Parker.
* Support for lzma decompression within adobe flash files.
* Support for mso attachments within microsoft office 2003 xml files.
* A new sigtool option(--ascii-normalize) allowing signature authors
to more easily generate normalized versions of ascii files.
* Windows installation directories changed from \program files\sourcefire\
ClamAV to \Program Files\ClamAV or \Program Files\ClamAV-x64.

- Make clamd and clamav-milter services depend on freshclam as
they need it

- Don't need sendmail for building clamav-milter anymore,
sendmail-devel is enough (boo#915414).

- Boo#914505: config file merging and temp file creation got moved
to %pre by mistake. Put them back to %post.
- Restore the updateclamconf script (boo#908731).
