removed hard-coded module reference in intialization

- Only the two voltage OKs are left to calculate the status
- Connected is not part of the status any more. It's already provided by the device
- INIT_OK does not exist any more. If the device is OK, it is always initialised

- Link server against DOOCS backend
- Fix typo in xlmap
- Remove loadlib in dmap
- Use CDD in dmap

Merge branch 'ApplicationCore' of doocs-git.desy.de:doocs/library/common/tc4eqfct into ApplicationCore

- Added install target and config to find the library
- Removed dependency on DoocsBackend
- DoocsAdapter only needed for test server

If a header-only library requires linking a 3rd party library, the ..._LIBRARIES variable could not be used in depending projects, because it
contained NOTFOUND.

Removed libtine linking workaround from FindDOOCS. Doocs libraries now are themselves linked correctly against tine.

Automatically adding CMAKE_CXX_STANDARD to all projects is giving too much trouble because different CMAKE versions add different --std=gnu... flags which do not play well the the --std=c++... which we use.

This reverts commit ddb4d575.

This confused git massively

The pkg-config file is missing so we have to search for the library
manually

This is a work-around for libDOOCSapi linking against it but expecting
/export/doocs/lib to be in the linker search path (not using rpath)

May be reverted once/if doocs fixes this

FindDOOCS: extend PKG_CONFIG_PATH by directory set via DOOCS_DIR (if set) and the hardcoded default in /export/doocs/...
