[__USE_EXTERN_INLINES]: Use glibc's __extern_inline machinery.

* libdiskfs/diskfs.h: Apply inline optimization only #ifdef
__USE_EXTERN_INLINES.  Use __extern_inline instead of extern inline.
* libftpconn/ftpconn.h: Likewise.
* libpipe/pipe.h: Likewise.
* libpipe/pq.h: Likewise.
* libshouldbeinlibc/idvec.h: Likewise.
* libshouldbeinlibc/maptime.h: Likewise.
* libshouldbeinlibc/ugids.h: Likewise.
* libstore/store.h: Likewise.
* libthreads/rwlock.h: Likewise.
* libdiskfs/extern-inline.c: Adapt to these changes.
* libftpconn/xinl.c: Likewise.  And don't #include "priv.h".
* libpipe/pipe-funcs.c: Likewise.
* libpipe/pq-funcs.c: Likewise.
* libshouldbeinlibc/idvec-funcs.c: Likewise.
* libshouldbeinlibc/maptime-funcs.c: Likewise.  And remove superfluous
includes.
* libshouldbeinlibc/ugids-xinl.c: Likewise.
* libstore/xinl.c: Likewise.
* libthreads/rwlock.c: Likewise.
