Hi ports@

I've reorganised the libfuse header files as a preperatory patch for
supporting the low-level FUSE API:

It introduces the following new files.

- /usr/include/fuse/fuse_common.h
- /usr/include/fuse/fuse_lowlevel.h
- /usr/src/lib/libfuse/fuse_chan.c

Additionally, it relocates all libfuse header files to the
/usr/include/fuse directory so that it now contains.

- /usr/include/fuse/fuse.h
- /usr/include/fuse/fuse_opt.h
- /usr/include/fuse/fuse_common.h
- /usr/include/fuse/fuse_lowlevel.h

This change avoids FUSE header clutter in /usr/include and aligns with
how Linux organises FUSE related headers.

Before I commit this patch to the source tree, I need to ensure that all
FUSE filesystems in ports still compile. I've run the following to
compile them all.

env SUBDIRLIST=/home/helg/fuse-ports.txt make FETCH_PACKAGES=

fuse-ports.txt contains:

archivers/fuse-zip
devel/fossil
security/encfs
security/libbde
security/libewf
#security/veracrypt
sysutils/curlftpfs
sysutils/libfsapfs
sysutils/libfsntfs
sysutils/libfvde
sysutils/libluksde
sysutils/libolecf
sysutils/libqcow
sysutils/libregf
sysutils/libsmraw
sysutils/libvhdi
sysutils/libvmdk
sysutils/libvshadow
sysutils/libvslvm
sysutils/ntfs-3g
sysutils/simple-mtpfs
sysutils/sshfs-fuse
sysutils/unionfs-fuse
sysutils/usmb

All except 3 compiled without problems. The below is a diff for fossil
and unionfs-fuse. veracrypt failed with a bunch of dependenciEs on my
system via make and pkg_add. Maybe someone else can test this.

Fossil successfully knows to add -lfuse to LIBS as port of configure
but doesn't also add -I/usr/include/fuse to CFLAGS. My understanding of
autoconfig is not good enough to know why.

Either way, by using pkg-config everything should work before and after
I commit my fuse headers patch.

ok?
