tl;dr The OpenSSL 1.0.2 releases suffer from a Key Recovery Attack on DH small subgroups. This issue got assigned CVE-2016-0701 with a severity of High and OpenSSL 1.0.2 users should upgrade to 1.0.2f. If an application is using DH configured with parameters based on primes that are not "safe" or not Lim-Lee (as the one in RFC 5114) and either Static DH ciphersuites are used or DHE ciphersuites with the default OpenSSL configuration (in particular SSL_OP_SINGLE_DH_USE is not set) then is vulnerable to this attack.
- added possibility to modify groups (e.g. edit circles)
- fixed mismatched free/delete in fimonitor.cc, authssl.cc, pqibin.cc (saving encrypted hash cache file)
- improved plugin interface class to allow plugins to access GXS objects.
- added method to un-register notify clients from RsNotify
- fixed pqisslproxy for windows, due to win not properly supporting sockets in non blocking mode.
- removed static members form RsInitConfig and made RsAccounts object a pointer. This prevents plugin initialisation problems at symbol resolving time.
- removed bool return from p3IdService::getOwnIds()

These split at 6672 -> 7075, so quite a bit merge.
libretroshare compiles - but untested.
retroshare-gui needs GenCertDialog.ui and IdEditDialog.ui to be properly merged. (compile errors).
some plugins will be broken.
retroshare-nogui is untested.

- the notification system is now a service, p3Notify, that is a public RsNotify.
- RsNotify does nothing except providing a registration system for new notify clients.
- Clients should derive a notify client from the NotifyClient class and register it to rsNotify
- all registered clients get all notifications, so only derive the needed methods. This should allow
plugins to get notifications as well.
- updated the code to call RsServer::notify()->[notification method] from inside libretroshare
- pqiNotify has been removed.

In preparation for making RS support IPv6.
NB: This breaks the build of retroshare-gui, as the
sockaddr_storage_xxx fns are only defined as prototypes for now.
All the aux libraries like udp / stun / tcponudp / dht have still to be converted.
These changes will probably break various things and need to be tested thoroughly.

- Fixed cipher list to "HIGH:!DSS:!aNULL:!3DES", which should disable the weak ones, no idea how to force it to PFS (which it should use).
- fixed void * pointer maths.

- added missing virtual functions in ftDataRecv
- setup initSSL instance as a static member of AuthSSL, instead of an external (does not change much except the init in rsinit.cc)
- changed p3PeerMgrIMPL to take SSL and PGP ids as parameters. This avoids calling AuthSSL and AuthGPG from the constructor => very helpful for tests.
- added random creation function in t_RsGenericId<>
- added functions setAuthSSL_debug() and setAuthGPG_debug() to manually setup the authSSL and authGPG objects to use. Used in tests.

This brings a huge amount of goodness into the trunk,
but there is still a big chunk todo before it can be released.
* GXS Backend.
* GXS Services:
- Identities.
- Circles

- Posted.

To switch on GXS stuff, enable CONFIG += gxs
in both libretroshare.pro and retroshare-gui.pro

- added automatic cleaning of certificates in both formats
- grouped all certificate cleaning/parsing code in rscertificate.cc
- removed unused files cleanupxpgp.h/cc
- added upper/lower case to rsid template.
The new format is to be tested. It is supposed to be much more robust than the previous format,
in particular, allowing any string for location names.

User-level changes:
==================
- libgpgme is not used anymore; it is replaced by a built-in piece of code called OpenPGP-SDK
(http://openpgp.nominet.org.uk/cgi-bin/trac.cgi) that was improved to be used by RetroShare
for handling PGP keys.
- the gnupg keyring is not used anymore. Now, RetroShare has it's own gpg keyring, shared by all instances.
On linux it's located in ~/.retroshare/pgp/. A lock system prevents multiple locations to read/write keyrings
simultaneously.
- the trust database from gnupg is not documented, so RetroShare cannot import it. This comes from the fact that
the GPG standard (RFC4880) asks explicitly not to export trust information. So RetroShare has it's own
trust DB shared by locations. This means you need to re-trust people. Sorry for that!
- at start, if no keyring is found, RS will propose to copy the gnupg keyring to use your existing keys. Clicking on
"OK" will do the copy, and you should find back all existing locations, except for DSA keys.
- locations for which the suitable keypair is not in the keyring will not be displayed in the login window
- locations for which the suitable keypair is not a RSA/RSA key will not be displayed. RetroShare does not
support DSA/Elgamal keypairs yet.
- a key import/export exchange function has been added in the certificate creation window (you go there from the login
window by clicking on "manage keys/locations". This allows to easily create a new location with the same pgp key on
another computer. To obtain a suitable keypair using gnupg, you need to concatenate the encrypted private key and the
public key into an ascii file. This can be done using:
gpg -a --export-secret-keys [your ID] > mykey.asc
gpg -a --export [your ID] >> mykey.asc
- importing a key with subkeys in not yet possible. Please remove subkeys before importing.
- The code has been tested for a reasonnable amount of time, but it's not possible to prevent some new bugs
to appear. Please report them asap supplying: call-stacks if possible, and terminal output. In particular,
openpgp has some assert()'s that should not be triggered unless RetroShare is calling it in an improper way.
Internal changes
================
- a specific component, PGPHandler, takes care of the interface between openpgp-sdk and RetroShare
openpgp-sdk is c-code, with it's own memory management, which has been kept well separated from
RetroShare.
- GPG Ids are now a specific class (not a std::string anymore) for code consistency reasons. As strings are
still used in many places, this requires a few conversions. In particular, AuthGPG takes strings as
function params and calls GPGHandler with the proper PGPIdType class. In the future, RetroShare should
only use PGPIdType. The same will be done for SSL ids.
- signature cleaning is still handled by the Retroshare built-in function, not by openpgp, but we will
do this later.
Still to do
===========
- DSA needs subkey handling, since the encryption is performed by a Elgamal subkey. Not sure this will be done.
- GPGIds/SSLIds cleaning (meaning replace strings by appropriate types). Lots of confusion throughout the code in retroshare-gui in particular.
- key removal from keyring. This is a challenge to keep locations synchronised.

- Fixed crash after the second call to RsInit::InitRetroShare when keyring does not exist.
The instance of AuthSSL was created twice and AuthGPG was deleted without stopping the thread. Stopped the AuthGPG thread on exit of RetroShare.
- Added the correct path to the keyring for Windows in RsInit::copyGnuPGKeyrings.
- Changed the detection of the portable version on Windows from the file "gpg.exe" to the file "portable".

Show "RetroShare" as sender of system messages to myself.
Added new quick view in MessagesDialog to filter system messages.
Changed RetroShare link in friend request message to certificate.
Added new subject image for the system messages (defnax).
Removed not used notify in message service.
Recompile needed.
