Bug#4035 - HiddenStores file not renamed every time.
Adding regression tests for the behavior reported in Bug#4035, and tweaking
the code to handle these cases.
Add support for a new %{file-offset} LogFormat variable, to store the file
offset at which a file transfer (upload or download) starts.
Stash the file-offset note for SCP transfers as well.  Fix up misleading
comments.
Add support for the %{file-offset} variable to mod_sql (and the missing
%{file-modified} variable).  Fixed formatting/printing of %{file-offset}
for ExtendedLog.
Merge branch 'master' into xfer-note-file-offset
Bug#4098 - mod_sftp unable to use SFTPHostKey due to being group readable in
CentOS 7.
Bug#4102 - Failure to build mod_tls when using static libcrypto due to libdl
linker errors.
Fix another place where the libdl linker flag may need to come earlier in
the list.
Bug#4102 - Failure to build mod_tls when using static libcrypto due to libdl
linker errors.

In the course of fixing this issue, I also fixed problems with configure's
detection of EC support in OpenSSL, and make it possible for mod_sftp to
build without zlib support.
Improve the detection of zlib support, and handling of the results, for
mod_sftp.
Make sure to add -lz, when needed, to the building of a DSO mod_sftp.
Make sure that if zlib support is lacking, mod_sftp does not to try negotiate
compression during the key exchange.
Updating NEWS.
