There's an unfortunate amalgamation of caller-provided pathconv_arg
flags with path_types flags which in turn are mostly mount flags.
This leads to a confusion of flag values in sylink_info::pflags and,
in turn, in path_conv::path_flags.
This patch decouples pathconv_flags from the other flags by making
sure that a pathconv_flag is never copied into a variable used for
path_types flags. Also, remove PATH_NO_ACCESS_CHECK since it's
not necessary.

Allows expressions along the lines of `cat /proc/self/fd/0 <<EOF'.
The problem here is that the temporary file used for the here script
has already been deleted by the shell. Opening by filename, as
implemented so far, doesn't work because the file has been moved
to the bin.
Allow reopening files by handle the same way from another process
as long as we have sufficient permissions on the foreign process.

So far we had two functions checking the content of a reparse point,
readdir_check_reparse_point in fhandler_disk_file.cc for the sake of
readdir, and symlink_info::check_reparse_point for the sake of
generic path checking.
* Rename check_reparse_point_target helper to check_reparse_point_string
and convert to static function.
* Create new check_reparse_point_target helper containing the core
reparse point checking code
* Just call check_reparse_point_target from readdir_check_reparse_point
and symlink_info::check_reparse_point and only perform the unique
task in those functions.

Revamp device parsing code. Introducing support for more partitions
into the shilka-generated parser has the unfortunate side-effect of
raising the size of the DLL by almost 2 Megs. Therefore we split out
the handling for /dev/sdXY devices into a tiny bit of hand-written
code.
While at it, remove some unused cruft from devices.* and generally
clean up the device class to provide access methods instead of direct
access to members.

Rather than having to check for the FS type in the caller and having
to call different functions whether FS is NFS or not, encapsulate the
info in path_conv_handle/path_conv methods to allow FS type agnostic
calling from upper level functions.
This patch only implements the methods.

* fhandler.h: Throughout, delete size(), add copyout, clone, and fhandler_*
(void *) methods.
(fhandler_base::reset): Rename from operator =().
(fhandler_termios::is_dev_tty): Delete.
(fhandler_termios): change "protected" region to "private".
(fhandler_termios::is_dev_tty): Delete.
(fhandler_termios): Rearrange protected/public.
(fhandler_termios::fhandler_termios): Remember last fhandler_termios "opened".
(fhandler_termios::~fhandler_termios): Forget last fhandler_termios opened.
(ioctl): Rename from ioctl_termios. Take a void * argument. Reflect argument
change in pinfo::set_ctty.
(fhandler_console::dup): Declare new function. Set ctty here if appropriate.
(fhandler_pty_master::from_master): Privatize.
(fhandler_pty_master::to_master): Ditto.
(fhandler_pty_master::dwProcessId): Ditto.
(fhandler_pty_master::fhandler_pty_master): Add an `int' argument.
(fhandler_pty_master::open_setup): Declare new function.
(fhandler_pty_master::~fhandler_pty_master): Declare new method.
(fhandler_nodevice): Remove commented out function declaration.
* fhandler_console.cc: Use get_ttyp() instead of tc() throughout.
(fhandler_console::dup): Define new function to set controlling ctty on dup, as
appropriate.
(fhandler_console::ioctl): Reflect ioctl_termios name change.
(fhandler_console::setup): Rename from get_tty_stuff.
(fhandler_console::open_setup): Reflect argument change in pinfo::set_ctty.
(fhandler_console::fhandler_console): Set _tc here.
* fhandler_termios.cc (handler_termios::ioctl): Rename. Take a void * arg like
other ioctl functions.
* fhandler_tty.cc (fhandler_pty_slave::dup): Call myself->set_ctty to
potentially reset the controlling terminal.
(fhandler_pty_slave::ioctl): Reflect name/arg change for ioctl_termios.
(fhandler_pty_slave::fhandler_pty_slave): Take a "unit" argument. Call setup()
here so that we will know the unit number of this fhandler as soon as possible.
Set the unit as appropriate.
(handler_pty_master::open): Move most stuff to constructor and open_setup.
(handler_pty_slave::open_setup): Reflect argument change in pinfo::set_ctty.
(handler_pty_master::open_setup): Define new function.
(fhandler_pty_master::cleanup): Clear handles as a flag that the destructor
does not have to do "close" operations.
(fhandler_pty_master::close): Ditto.
(fhandler_pty_master::~fhandler_pty_master): Define new method.
(fhandler_pty_master::ioctl): Reflect name/arg change for ioctl_termios.
(fhandler_pty_master::setup): Allocate tty here. Rely on handles being
returned from allocated test rather than opening them here. Avoid setting
_need_nl here since it is already zeroed in the constructor. Set up device
information with DEV_TTYM_MAJOR.
* path.h (path_conv &operator =): Take a const argument.
(path_conv::dup): Ditto.
(pathconv_arg::PC_OPEN): New enum.
(pathconv_arg::PC_CTTY): Ditto.
(path_types::PATH_CTTY): Ditto.
(path_types::PATH_OPEN): Ditto.
(path_conv::isopen): New method.
(path_conv::isctty_capable): Ditto.
* path.cc (path_conv::check): Set PATH_OPEN and PATH_CTTY as appropriate.
* pipe.cc (fhandler_pipe::open): Use copyto to copy pipe handle.
* syscall.cc (open): Reinstate fd > 2 check to disallow resetting ctty on
non-std* handles.
* tty.cc (tty_list::allocate): Pass out handles for allocated tty. use
`not_allocated' to find unallocated ttys. Avoid keeping the lock since the
allocation of the tty should be sufficient to prevent multiple access.
(tty::not_allocated): Clarify comment. Rename. Return handles when an unused
tty is found. Simply test for existing tty.
(tty::exists): Rewrite to use `not_allocated'.
* tty.h (NTTYS): Reset down to actual number supported by devices.in.
(tty::not_allocated): Declare new function.
(tty_list::allocate): Pass out read/write tty handles. Zero them when not
found.
* fhandler_proc.cc: Reflect name change from FH_PTYM -> FH_PTMX.
* pinfo.h (pinfo::set_ctty): Reduce/reorder arguments passed in.
* pinfo.cc (pinfo::set_ctty): Ditto. Just use tc() built into the passed-in
fhandler_termios pointer. Return true if ctty is assigned.
* syscalls.cc (open): Call build_fh_pc with PC_OPEN flag. Set PC_CTTY if
appropriate.
(stat_worker): Remove is_dev_tty () stuff.
