Move errno.h to common-defs.h

This commit moves the inclusion of errno.h to common-defs.h and
removes all other inclusions.  Note that prior to this commit
server.h included errno.h protected by "#ifdef HAVE_ERRNO_H".
This protection was added with the Windows CE port, which is
currently broken.  Since no other platform needs this, I have
removed the protection and the configury to support it.
