Hello!
I have the following three patchsets for Neon 0.25.3
1) patch-auth -- fix use of GSSAPI. Streamline generation of 16
random bytes -- this hunk is only portable, to where there is
srandomdev(), but OpenSSL is not required;
2) patch-md5 -- when already using OpenSSL (almost always), use
OpenSSL's MD5 implementation, instead of Neon's own. It is, probably,
more reliable and, sometimes, assembly- and/or hardware-optimized.
3) patch-tests -- several tests were failing. Please, take a look.
Some of these are, I'm sure, misguided... The patch also makes the
certificate-generation (for wildcard* tests) independant from Linux.
Instead of Linux-only features of hostname(1), it uses much wider
spread
features of modern sh (or bash or ksh) -- and now works on FreeBSD as
well.
Now, if only someone could update cadaver to work with the new neon...

This patch fixes the GSSAPI use and makes use the srandomdev/random
functions, which provide cryptographically strong random numbers.
gss_release_oid() does not even exist in FreeBSD's Heimdal Kerberos.
On Solaris, it does exist, but its use is discouraged. In particular,
the gss_init_sec_context manual page on Solaris explicitly states:
actual_mech_type
The actual mechanism used. The OID returned by means
of this parameter will be pointer to static storage
that should be treated as read-only. The application
should not attempt to free it. To obtain a specific
default, supply the value GSS_C_NO_ID. Specify NULL if
the parameter is not required.
Submitted to NEON developers.

This patch makes Neon use OpenSSL's md5 implementation, if
available. The ne_md5_stream is eliminated completely -- it
is not used by anything.
