instead of puffs_start(). Get completely rid of puffs_start(), as
everything it used to do is now handled by the mount routine.
Introduce an optional pre-mount call puffs_setrootinfo() for setting
non-default root node information. As the old puffs_mount() is
now virtually useless, say byebye to it and rename the old
puffs_domount() to puffs_mount(), but add a root cookie parameter
to compensate for the late puffs_start().

- Use malloc and free instead of macros, delete macros.
- Merge the two copies of deep copy and free args that were slightly buggy
into one and use that one.

Provide a default for FUSE_USE_VERSION if it's not set, and use this

Be consistent with the mount name processing, and always do the

support removal and addition of i/o file descriptors on the fly.
* detect closed file descriptors
* automatically free waiters of a dead file descriptor
* give the file server the possibility to specify a callback which
notifies of a dead file descriptor
* move loop function to be a property of the mainloop instead of
framebuf (doesn't change effective behaviour)
* add the possibility to configure a timespec parameter which
attempts to call the loop function periodically
* move the event loop functions from the puffs_framebuf namespace
to puffs_framev to differential between pure memory management

dynamic add/remove of fd's. (not tested except for one fd, but more
changes coming soon)

pthread gets confused since we aren't running on the regular stack.
I'm not really sure which direction to go to with this quite yet, so
make the hack hard to enable on purpose. The whole request dispatch
code needs cleaning anyway.
and event handling mechanisms required in file servers with blocking
I/O backends. puffs_framebuf is built on the concept of puffs_cc
and uses those to multiplex execution where needed.
File systems are required to implement three methods:
* read frame
* write frame
* compare if frame is a response to the given one
Memory management is provided by puffs_framebuf, but the file
systems must still, of course, interpret the protocol and do e.g.
byte order conversion.
As always, puffs_framebuf is work in progress. Current users are
mount_psshfs and mount_9p.
Refuse doessn't have a fuse_common.h, so include fuse_opt.h explicitly
from fuse.h. To avoid circular dependencies, don't include fuse.h
from fuse_opt.h.
This means that we no longer have to modify packages which use the argument
and option parsing routines to include fuse_opt.h.
It was only ever non-zero for zombies, and now doesn't exist.
The 'pstats' field has been valid for zombies for a while (it isn't in
the uarea any more).
Fixes part of build breakage.
- Add POSIX defined system variables and constants of AIO_LISTIO_MAX and
AIO_MAX values. Both with _POSIX_ASYNCHRONOUS_IO, provide them in
sysconf(3) and getconf(1) interfaces.
- Clean up sysconf(3) for handling sysctl nodes dynamically.
Seems to be quite stable. Some work still left to do.
Please note, that syscalls are not yet MP-safe, because
of the file and vnode subsystems.

+ put some meat into the add_arg and insert_arg functions
+ implement the free_args function
+ use 0 and 1 return values, instead of EXIT_SUCCESS and EXIT_FAILURE, in
internal functions (they bear no relation to shell exit values)
+ deep copy argument structures in refuse.c - we need to do this because
some FUSE file systems attempt to obliterate^Wcloak the argument vector
"for security reasons"
+ a side benefit of this is that we get the specific refuse file system

only take the bare essentials, which currently means removing
"maxreqlen" from the argument list (all current callers I'm aware
of set it as 0 anyway). Introduce puffs_init(), which provides a
context for setting various parameters and puffs_domount(), which
can be used to mount the file system. Keep puffs_mount() as a
shortcut for the above two for simple file systems.

After resuming execution, the thread must check to see if it
has been restarted as a result of pthread_cond_signal(). If it
has, but cannot take the wakeup (because of eg a pending Unix
signal or timeout) then try to ensure that another thread sees
it. This is necessary because there may be multiple waiters,
and at least one should take the wakeup if possible.

Thanks to Mihai Chelaru for providing access to an amd64 machine
for debugging this problem.
Unfortunately it is too difficult to make vfwscanf and this share
the same code like I did with printf, because for string parsing
the code is too different.
