Add explicit NSPR_CFLAGS and NSS_CFLAGS where NSPR_LIBS and NSS_LIBS is
used.

Use DIRSRV_CFLAGS rather than hardcode -I/usr/include/dirsrv.

Append NSPR_CFLAGS to DIRSRV_CFLAGS in ./configure as slapi-plugin.h
includes nspr.h.

Automake manual section 13 What Gets Cleaned says that make maintainer-clean
should not remove files necessary for subsequent runs of ./configure.

It practically means that all usage of MAINTAINERCLEANFILES were incorrect
so I've removed them.

This is step forward working VPATH builds which cleanly separate sources
and build artifacts. It makes the system cleaner and easier to
understand.

Whenever we upgrade IPA such that any data incompatibilities might occur
then we need to bump the DATA_VERSION value so that data will not
replicate to other servers. The idea is that you can do an in-place
upgrade of each IPA server and the different versions own't pollute
each other with bad data.
