[Softhsm-develop] SoftHSM 2.6.0rc1

[Berry A.W. van Halderen]

Dear all,

I've compiled a release candidate for SoftHSM 2.6.0 (RC1).  I'd
like to known any issues that are blocking promoting this to
a proper release.

SoftHSM 2.6.0 is a continuation of the 2.5.x branch, and when
released willreplace the 2.5 branch for any patches for bug
fixes, discontinuing support for that branch.  Since this is
a continuation of the development containing mostly fixes
and improvements.

However one thing to be aware of is the switch to Botan version 2.
SoftHSM is build with either a back-end of OpenSSL or Botan and
cannot support both at the same time and Botan 1 was declared end
of life some time ago, so a switch to Botan 2 was really needed.
Windows build are only partial supported at this time.

No migration, configuration changes or path changes are necessary
and the build configuration should not need changing.
