Corinna Vinschen a52993d426 * fhandler_proc.cc: Add /proc/filesystems virtual file.
(format_proc_filesystems): New function.
	* mount.cc (fs_names): Move to global scope. Redefine as array

Corinna Vinschen 002a34fa14 * mount.h (fs_info::inited): New inline method.
* path.cc (path_conv::check): Clear filesystem info if following a
	symlink.  Use new fs_info::inited method to check if FS info is already
	available.
	(symlink_info::check): Drop fs_update_called.  Use fs_info::inited
	method instead.  Streamline test for leading space and trailing dot or
	space.  Add comments.

Corinna Vinschen 6ff06a0726 * mount.cc (GETVOLINFO_VALID_MASK): Drop FILE_SEQUENTIAL_WRITE_ONCE
from mask.  Expand the comment a bit.
	(WIN_FAT_FLAGS): New define.

	* mount.h (class fs_info): Add has_dos_filenames_only status flag.
	Implement accessors.
	* path.cc (symlink_info::check): Rearrange variable definitions to

	If all checks point to one of that, restart method with tweaked
	incoming path.  Add lengthy comments to explain what we do.
