Fix extern inline use

* ext2fs/Makefile (SRCS): Add xinl.c
* libtreefs/Makefile (OTHERSRCS): Likewise.
* term/Makefile (SRCS): Likewise.
* ufs/Makefile (SRCS): Likewise.

* hostmux/hostmux-xinl.c: Define HOSTMUX_DEFINE_EI instead of HOSTMUX_EI.
* libdiskfs/extern-inline.c: Define DISKFS_DEFINE_EXTERN_INLINE instead of
DISKFS_EXTERN_INLINE.
* libftpconn/xinl.c: Define FTP_CONN_DEFINE_EI instead of FTP_CONN_EI.
* libpipe/pipe-funcs.c: Define PIPE_DEFINE_EI instead of PIPE_EI.
* libpipe/pq-funcs.c: Define PQ_DEFINE_EI instead of PQ_EI.
* libshouldbeinlibc/idvec-funcs.c: Define IDVEC_DEFINE_EI instead of
IDVEC_EI.
* libshouldbeinlibc/maptime-funcs.c: Define MAPTIME_DEFINE_EI instead of
MAPTIME_EI.
* libshouldbeinlibc/ugids-xinl.c: Define UGIDS_DEFINE_EI instead of
UGIDS_EI.
* libstore/xinl.c: Define STORE_DEFINE_EI instead of STORE_EI.
* libthreads/rwlock.c: Define RWLOCK_DEFINE_EI instead of RWLOCK_EI.
* ext2fs/xinl.c: New file, define EXT2FS_DEFINE_EI and include "ext2fs.h"
* libtreefs/xinl.c: New file, define TREEFS_DEFINE_EI and include "treefs.h"
and "mig-decls.h".
* term/xinl.c: New file, define TERM_DEFINE_EI and include "term.h".
* ufs/xinl.c: New file, define UFS_DEFINE_EI and include "ufs.h"

* ext2fs/ext2fs.h: Include <features.h>, define EXT2FS_EI to __extern_inline
instead of "extern inline", define it to empty when EXT2FS_DEFINE_EI is
defined. Always declare extern inline prototypes, and define extern inlines
content only if __USE_EXTERN_INLINES or EXT2FS_DEFINE_EI is defined.
* libdiskfs/diskfs.h: Likewise with DISKFS_EXTERN_INLINE and
DISKFS_DEFINE_EXTERN_INLINE.
* libftpconn/ftpconn.h: Likewise with FTP_CONN_EI and FTP_CONN_DEFINE_EI.
* libftpconn/priv.h: Likewise.
* libpipe/pipe.h: Likewise with PIPE_EI and PIPE_DEFINE_EI.
* libpipe/pq.h: Likewise with PQ_EI and PQ_DEFINE_EI.
* libshouldbeinlibc/idvec.h: Likewise with IDVEC_EI and IDVEC_DEFINE_EI.
* libshouldbeinlibc/maptime.h: Likewise with MAPTIME_EI and
MAPTIME_DEFINE_EI.
* libshouldbeinlibc/ugids.h: Likewise with UGIDS_EI and UGIDS_DEFINE_EI.
* libstore/store.h: Likewise with STORE_EI and STORE_DEFINE_EI.
* libthreads/rwlock.h: Likewise with RWLOCK_EI and RWLOCK_DEFINE_EI.
* term/term.h: Likewise with TERM_EI and TERM_DEFINE_EI.
* ufs/ufs.h: Likewise with UFS_EI and UFS_DEFINE_EI.
* libtreefs/treefs.h: Include <features.h>, define TREE_FS_EI to
__extern_inline, or to empty when TREEFS_DEFINE_EI is defined. Use TREEFS_EI
instead of "extern inline".
* libtreefs/mig-decls.h: Use TREEFS_EI instead of "extern inline".
