Revert "SyncML: workarounds for broken peers" 

This reverts commit 3a71a2bf53 and
commit a0375e0160.

Need to back out the workaround for broken peers because it breaks
SyncEvolution<->SyncEvolution syncing.

* SyncML: workarounds for broken peers
Some peers have problems with meta data (CtCap, old Nokia phones) and
the sync mode extensions required for advertising the restart
capability (Oracle Beehive).
Because the problem occurs when SyncEvolution contacts the peers
before it gets the device information from the peer, dynamic rules
based on the peer identifiers cannot be used. Instead the local config
must already disable these extra features in advance.
The "SyncMLVersion" property gets extended for this. Instead of just
"SyncMLVersion = 1.0" (as before) it now becomes possible to say
"SyncMLVersion = 1.0, noctcap, norestart".
"noctcap" disables sending CtCap. "norestart" disables the sync mode
extensions and thus doing multiple sync cycles in the same session
(used between SyncEvolution instances in some cases to get client and
server into sync in one session).
Both keywords are case-insensitive. There's no error checking for
typos, so beware!
The "SyncMLVersion" property was chosen because it was already in use
for configuring SyncML compatibility aspects and adding a new property
would have been harder.
* EDS: fix creating databases
--create-database was broken in combination with the final code in EDS
