a61c08a2c8 Handle NULL returns from calloc() in sample plugins.
This is basic housekeeping, adding NULL checks to context initialization
of the sample plugin collection which are missing it.  Realistically,
this can never happen, but since these are supposed to be "good examples",
not checking calloc() return isn't one.

6690769f78 plugin: Export base64 encode and decode functions
This patch builds on the "Export secure_memzero() to plug-ins" patch and
adds export of openvpn_base64_encode() and openvpn_base64_decode()

This also ships with a very simple plug-in which demonstrates how to use
the new exported functions.

499794596d Update copyright to include 2018 plus company name change
The autumn of 2017, OpenVPN Technologies, Inc changed name to just
OpenVPN Inc.  Otherwise, extend the copyright to cover 2018 as well.

With the exception of the company name change, all changes have been
performed by the dev-tools/update-copyright.sh script.

caa54ac398 copyright: Update GPLv2 license texts
The COPYRIGHT.GPL file was slightly out-of-sync with the last GPLv2
license from Free Software Foundation, Inc.

The changes are primarily a new address, which required touching almost
all the project files.

Except of that, it is just minor adjustments to formatting, removal of
form-feed characters and referencing "GNU Lesser General Public License"
instead of "GNU Library General Public License".

Require minimum OpenSSL 1.0.1
As RHEL 5 has reached EOL, we no longer need to support OpenSSL v0.9.8.
This also makes it possible to remove a few workaronds which was
needed earlier, as well as some left overs from v0.9.6.

This also makes ./configure really stop running unless a new enough
OpenSSL library is found.

Compile tested on RHEL7.3 and RHEL6.7 (mock chroot build), both shipping
openssl-1.0.1e.

ec828db63f Remove ENABLE_SSL define (and --disable-ssl configure option)
Remove the --disable-ssl configure option and accompanying ENABLE_SSL
defines in the master/2.4 branch, to reduce the code and testing
complexity a bit.

This does not remove to runtime option to run without SSL, just the compile
time option to not include any SSL-related code.

During the community meeting in November 2014 there were no objections
amongst he developers present. Also, this has been announced on the -users
and -devel mailing lists two weeks ago, without any response whatsoever.

587df08abd plugin: Extend the plug-in v3 API to identify the SSL implementation used
OpenVPN would segfault unexpectedly if it would be compiled against
PolarSSL
and the plug-in would expect OpenSSL, or vice-versa.  This segfault would
not appear before the plug-in would try to access functions which would
be available if the plug-in and OpenVPN uses the same SSL implementation.

This patch adds a member to the plug-in initialisation function, which
identifies the SSL implementation.

The log_v3 plug-in is updated accordingly + a simple fix to make it
buildable again using the ./build script.

A minor documentation error in the openvpn-plugin.h was also
corrected, where it mentioned OPENVPN_PLUGIN_VERSION instead of
OPENVPN_PLUGINv3_STRUCTVER.

 v2 - add const ovpnSSLAPI ssl_api at the end of
      struct openvpn_plugin_args_open_in and not in the "middle"

 v3 - fix bug in plug-in init, as the SSLAPI was located wrong in the
      args struct sent to the openvpn_plugin_open_v3() function.

 v4 - Ensure SSLAPI got a sane/known value if SSL is disabled or unknown
