Revert r330897:
This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code.
Revert with prejudice.
This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes.
Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes.

MFC r321839:
Implement proper Linux /dev/fd and /proc/self/fd behavior by adding Linux specific things to the native fdescfs file system.
Unlike FreeBSD, the Linux fdescfs is a directory containing a symbolic links to the actual files, which the process has open. A readlink(2) call on this file returns a full path in case of regular file or a string in a special format (type:[inode], anon_inode:<file-type>, etc..). As well as in a FreeBSD, opening the file in the Linux fdescfs directory is equivalent to duplicating the corresponding file descriptor.
Here we have mutually exclusive requirements: - in case of readlink(2) call fdescfs lookup() method should return VLNK vnode otherwise our kern_readlink() fail with EINVAL error; - in the other calls fdescfs lookup() method should return non VLNK vnode.
For what new vnode v_flag VV_READLINK was added, which is set if fdescfs has beed mounted with linrdlnk option an modified kern_readlinkat() to properly handle it.
For now For Linux ABI compatibility mount fdescfs volume with linrdlnk option:
mount -t fdescfs -o linrdlnk null /compat/linux/dev/fd

Remove the thread argument from the FSD (File-System Dependent) parts of the VFS. Now all the VFS_* functions and relating parts don't want the context as long as it always refers to curthread.
In some points, in particular when dealing with VOPs and functions living in the same namespace (eg. vflush) which still need to be converted, pass curthread explicitly in order to retain the old behaviour. Such loose ends will be fixed ASAP.
While here fix a bug: now, UFS_EXTATTR can be compiled alone without the UFS_EXTATTR_AUTOSTART option.
VFS KPI is heavilly changed by this commit so thirdy parts modules needs to be recompiled. Bump __FreeBSD_version in order to signal such situation.

- Add locking to all filesystem operations in fdescfs and flag it as MPSAFE. - Use proper synhronization primitives to protect the internal fdesc node cache used in fdescfs. - Properly initialize and uninitalize hash. - Remove unused functions.
Since fdescfs might recurse on itself, adding proper locking to it needed some tricky workarounds in some parts to make it work. For instance, a descriptor in fdescfs could refer to an open descriptor to itself, thus forcing the thread to recurse on vnode locks. Because of this, other race conditions also had to be fixed.

Make VFS_ROOT() and vflush() take a thread argument. This is to allow filesystems to decide based on the passed thread which vnode to return. Several filesystems used curthread, they now use the passed thread.

KSE Milestone 2 Note ALL MODULES MUST BE RECOMPILED make the kernel aware that there are smaller units of scheduling than the process. (but only allow one thread per process at this time). This is functionally equivalent to teh previousl -current except that there is a thread associated with each process.
Sorry john! (your next MFC will be a doosie!)

o Move from Alfred Perstein's "exclusion" technique of handling special file types to requiring all file types to properly implement fo_stat. This makes any new file type additions much easier as this code no longer has to be modified to accomodate it.
o Instead of using curproc in fdesc_allocvp, pass a `struct proc' pointer as a new fifth parameter.

- Do not allow VOP_SETATTR to modify underlying vnodes at all. This caused problems when fetch(1) was passed `-o -'. The rationale of this change is that applications attempting to change underlying vnodes for /dev/fd nodes are improperly written and the use of this interface should not ever have been encouraged. Proper alternatives are fchmod, fchown and others.
PR: 18952
- Remove stale, unused fdescnode->fd_link structure member.

Adapt fdesc to be mounted on /dev/fd and remove fd, stdin, stdout and stderr nodes. More specific items of this patch: o Removed support for symbolic links, and the need for fdesc_readlink(). o Put all the code from fdesc_attr() into fdesc_getattr() and removed fdesc_attr(). This also made it easier to properly give all nodes unique inode numbers. o The removal of all non-fd nodes allowed the removal of the fdesc_read(), fdesc_write(), and fdesc_ioctl() nodes, since we no longer have nodes that get special handling. o Correct the component name validity-checking in fdesc_lookup(). It previously detected the end of the string by checking for a terminating NUL, now it uses cnp->cn_namelen. o Handle kqueue files as FIFOs. This is probably the closest file type to represent this type of file there is, and it is unfortunately not very representative of a kqueue. Creation time is not supported by kqueue, so ctime, mtime and atime are all set to the current time when getattr() was called. o Also set st_[mca]time to the current time since there's no data in socket structures that can be used to fill this in (FIFOs). o Simplify fdesc_readdir() since it only has to report the numbered fd nodes. Add `.' and `..' directory links as well. o Remove read bits from directories as they tend to confuse programs like tar(1).

Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL" is an application space macro and the applications are supposed to be free to use it as they please (but cannot). This is consistant with the other BSD's who made this change quite some time ago. More commits to come.

This is the kernel Lite/2 commit. There are some requisite userland changes, so don't expect to be able to run the kernel as-is (very well) without the appropriate Lite/2 userland changes.
The system boots and can mount UFS filesystems.
Untested: ext2fs, msdosfs, NFS Known problems: Incorrect Berkeley ID strings in some files. Mount_std mounts will not work until the getfsent library routine is changed.

Introduced a type `vop_t' for vnode operation functions and used it 1138 times (:-() in casts and a few more times in declarations. This change is null for the i386.
The type has to be `typedef int vop_t(void *)' and not `typedef int vop_t()' because `gcc -Wstrict-prototypes' warns about the latter. Since vnode op functions are called with args of different (struct pointer) types, neither of these function types is any use for type checking of the arg, so it would be preferable not to use the complete function type, especially since using the complete type requires adding 1138 casts to avoid compiler warnings and another 40+ casts to reverse the function pointer conversions before calling the functions.
