* path.h (pathconv_arg): Add PC_POSIX.

Browse Source 
(path_conv): Add normalized_path field.
* path.cc (path_conv::~path_conv): New destructor.
(path_conv::check): Set normalized_path, where appropriate.
* dtable.cc (build_fhandler_from_name): Use normalized path from path_conv.
* syscalls.cc (chroot): Ditto.
* cygheap.h: Remove path_prefix_p declaration.  Christopher Faylor
<cgf@redhat.com> (minor fixups)
* Makefile.in: Add fhandler_proc.o, fhandler_registry.o, fhandler_process.o and
fhandler_virtual.o.
* dtable.cc (dtable::build_fhandler): Add entries for FH_PROC, FH_REGISTRY and
FH_PROCESS.  Set unix_name to the normalized posix path.
* fhandler.h: Add constants for FH_PROC, FH_REGISTRY and FH_PROCESS.  Add class
declarations for fhandler_virtual, fhandler_proc, fhandler_registry and
fhandler_virtual.  Update fhandler_union accordingly.
* fhandler_proc.cc: New file.  Add implementation for fhandler_proc.
* fhandler_virtual.cc: New file.  Add implementation for fhandler_virtual.
* fhandler_process.cc: New file.  Add implementation for fhandler_process.
* fhandler_registry.cc: New file.  Add implementation for fhandler_registry.
* path.cc: Add isproc and isvirtual_dev macros.
* path.cc (path_conv::check): Add check for virtual devices.
* path.cc (mount_info::conv_to_win32_path): Convert paths in /proc to empty
Win32 paths.
* path.cc (chdir): Replace check for FH_CYGDRIVE with more generic
isvirtual_dev macro.  Force setting of posix path for virtual fhandlers.
* path.h: Add externally visible path_prefix_p and normalized_posix_path
prototypes.
