Replace usages of B_FILE_NOT_FOUND in non-BeOS-API code.

B_FILE_NOT_FOUND was deprecated in BeOS R5 in favor of B_ENTRY_NOT_FOUND,
but it remained in Haiku and was never removed even conditionally, so
we have accumulated a number of usages of it.

This commit changes all the usages of it in new code, applications,
or anything else that BeOS applications will otherwise never see,
and so should be relatively safe.

nfs4: support hard links properly

The main purpose of this patch is to prevent VFS from removing a vnode to early
what might have happened if the NFS client knew it had more than one name but
then one of them was deleted. Moreover, all discovered and still valid names
are stored what may be useful in proper file handle recovery when they are
volatile.

This patch fixes both #9558 and #9561.

nfs4: Fix memory leaks in case of errors while reading a directory

This fixes CID 991497.

nfs4: Fix memory leaks in case of error in ReplyInterpreter::_DecodeAttrs()

This patch fixes CID 991505, 991504, 991502, 991500, 991499, 991496.

nfs4: Fix wrong parenthesising in ReplyInterpreter::_FlattenPathname

This patch solves CID 990966.

nfs4: VFS uses signed offsets while NFS4 expects unsigned

nfs4: Fix problems with reading directory entries
* Inode::ReadDir missed an entry when given buffer was too small
* Each OpenDirCookie now has its own copy of directory snapshot what
would prevent Inode::ReadDir from accessing freed memory when removing
files and reading directory entries simultaneously
* Several minor issues fixed

nfs4, dns_resolver: fix numerous style violations

nfs4: Fix node removal

nfs4: Fix gcc4 warnings

nfs4: Add basic emulation of named attributes

nfs4: Fix server reboot recovery

nfs4: Use one open state per inode

nfs4: Use global open owner, check whether delegation was granted

nfs4: Use unstable writes and commit before close

nfs4: Fix several issues introduced in previous commits

nfs4: Add full directory cache implementation

nfs4: Do not let local changes invalidate cache

nfs4: Add directory and name basic implementation

nfs4: Rename Filehandle to FileHandle and Filesystem to FileSystem

nfs4: Add id mapper

nfs4: Add proper lock owners management

nfs4: Check for reace conditions in filehandle recovery

nfs4: Verify inode number before opening a file

nfs4: Add support for file locking

nfs4: Add support for O_NONBLOCK mode

nfs4: Add write_stat() hook

nfs4: Improve handling errors in NFS replies

nfs4: Add write() hook

nfs4: Add create_symlink() hook

nfs4: Add unlink() and remove_dir() hooks

nfs4: Add rename() hook

nfs4: close*() should wake all blocked operations

nfs4: Add support for server migration

nfs4: Fix ReadDir() bug when skipping inodes

nfs4: Forbid accessing multiple NFS4 filesystems from one local mount

Haiku assumes that a pair dev_t:ino_t uniquely identifies a file. That may not be the case if we allow multiple filesystems share one dev_t.

nfs4: Add read_fs_info hook

nfs4: Let ReplyInterpreter provide original NFS4 error codes

nfs4: Add read_symlink() hook

nfs4: Renew all owned and used leases

nfs4: Let stat() retrieve access, change, etc dates

nfs4: Add Request class for better handling of NFS4 requests

nfs4: Fix off-by-one bug in READDIR decoding

nfs4: Add close() and free_cookie() hooks

nfs4: Add read() hook

nfs4: Add open() hook

nfs4: readdir() should not read more than requested

Additionally, file attribute decoding checks more strictly whether
received data are sane.

nfs4: Add read_dir() hook

nfs4: Add basic nfs4_read_stat() procedure

Not all data are retrieved and there is a room for improvement in handling
situations when server does not provide necessary information.

nfs4: Add NFS4 reply interpreter

Currently supported operations are: ACCESS, GETATTR (partially), GETFH,
LOOKUP and PUTROOTFH.
