Removed process.h include from cdo_int.h and added it to cdo.h.

A-Z.cc:
    Added cdo.h to Module files that were missing it.

added files: pstream_int.cc, pstream_int.h:
    created - files (pstream_int.cc/h) that contain functions used within operators and
              allow direct usage of pstream_t (e.g. pstreamDefVlist).

moves from pstream.cc to process.cc:
    func    - query_user_exit: required the processInqPrompt function causing a dependency
                on process.h and added include for <sys/stat.h>
    call    - query_user_exit from pstream_t::pstreamOpenWritePipe(const char*, int) to
                function cdoStreamOpenWrite(int, int)
    func    - cdoInitialize
                required process.h

process.cc:
    removed - pipe name creation from addFileInStream. The constructor of pipe_t creates the filename
    change  - processInqPrompt now calls process_t::inqPrompt() to get process_t::prompt
    added   - function process_t::inqPrompt()
    change  - function process_t::addNvals(size_t) now used in cdoCloseStream
    added   - function process_t::addNvals(size_t)
    changed - accces of pthreadScope, variable can be accessed directly without getPthreadScope()
    added   - process_t::cdoCloseStream(int)

Afterburner.cc:
    changed addition of Nvals to using new process_t::addNvals(size_t)

Arith.cc:
    removed - multiple // before pstreamClose() calls

pstream.cc:
    added   - include for std::map
    removed - include for cdo.h         not needed anymore
    removed - include for modules.h     not needed anymore
    removed - include for process.h     not needed anymore
    added   - static variable processNum
    added   - function for setting static variable processNum
    removed - setting of pstream name in pstream_create(int, int)
    changed - return function head of avoid pstream_t::pstreamOpenReadPipe(const char*)
              to int pstream_t::pstreamOpenReadPipe().
    removed - pstream_t::createFileLit(const char *)
                was unused
    changed - calls of processNums() to direct acces of static variable processNums
                this is only temporaty until timers are started and stopped by process_t
    removed - old version of pstream_t::pstreamOpenWriteFile(const char*, int)
                was unused
    split   - pstreamCloseParentStream(pstream_t*) into pstream_t::closePipe() and pipe_t::close()
                this removed code duplication
    split   - pstreamCloseChildStream(pstream_t*) int pstream_t::waitForPipe() and pipe_t::close()
                this removed code duplication
    removed - const int &getPthreadScope()
                unused
cdo.cc;
    merged  - if statement
                same variable used

cdo.h;
    added   - include for pstream_int.h
    added   - include for process.h

cdo_int.h:
    removed - include for process.h

pstream_write:
    removed - function declarations that are now in pstream_int.h

util.h:
    removed - function declarations that are now in process.h

CdoMagicsWrapper.h:
    added   - include for cdo.h

StringUtilities.h:
    added   - include for cdo.h

pipe.cc:
    added   - function pipe_t::close()
                handles releasing of pipe locks and sets pipe_t member
                EOP true

pipe.h:
    added   - declaration of function pipe_t::close()
