1.43 (dfr 04-Apr-97): * [dfr] Kludge until I get around to fixing all the vfs locking.
1.43 (dfr 04-Apr-97): */
The new devfs doesn't support VFS locking. So don't do locking
assertions for devfs vnodes.
With this change, a kernel with options DEBUG_VFS_LOCKS actually
gets to single-user mode.

LRU fashion when the listen queue fills up. Previously, there was
no mechanism to kick out old sockets, leading to an easy DoS of
daemons using accept filtering.

- When an error occurs processing one file, we must continue to process
the remaining files.
- Convert trailing whitespace to tabs as appropriate.
- Align backspace handling with what the verification suite expects.

- malformed environment strings (ones without an '=') were not rejected.
There shouldn't be any of these, but when the static environment is
empty it always begins with one of these; this one should be considered
as the terminator after the end of the environment, but it isn't.
- the comparison of the name being looked up with the name in the
environment was fuzzy -- only the characters up to the length of the
latter were compared, so _getenv_static("foobar") matched "foo=..."
in the environment and everything matched "" in the empty environment.

Garbage pointers in __si_u were not cleared by destroy_dev(). Not
clearing si_disk made the above fatal because the disk layer uses
si_disk as a flag to indicate that the dev_t has been completely
initialized. disk_destroy() clears si_disk for the parent dev_t
but doesn't get called for children.
Not fixed:
- setting the undocumented sysctl debug.free_devt should cause more
complete destruction of the dev_t including clearing of __si_u, but
actually causes the above to panic a little earlier.
- the loop leaks 10 memory allocations per iteration (4 DEVFS, 2 devbuf
and 4 dev_t).

the symbol index defined by the relocation. The elf_lookup() support
function is to be used by elf_reloc() when symbol lookups need to be
done. The elf_lookup() function operates on the symbol index and
will do a symbol name based lookup when such is required, otherwise
it uses the symbol index directly. This solves the problem seen on
ia64 where the symbol hash table does not contain local symbols and
a symbol name based lookup would fail for those symbols.
Don't pass the symbol name to elf_reloc(), as it isn't used any more.
Exit with nonzero status if a conversion failed.
Play nice if used as a shell builtin (currently disabled).
