418d67b0d9 Revert part of the last commit, remove {g|s}etflags from the libc
interface, and statically link them to the programs using them.
These functions, upon reflection and discussion, are too generically
named for a library interface with such specific functionality.
Also the api that they use, whilst ok for private use, isn't good
enough for a libc function.

Additionally there were complications with the build/install-world
process.  It depends heavily upon xinstall, which got broken by
the change in api, and caused bootstrap problems and general mayhem.

There is work in progress to address future problems that may be
caused by changes in install-chain tools, and better names for
{g|s}etflags can be derived when some future program requires them.
For now the code has been left in src/lib/libc/gen (it started off
in src/bin/ls).

It's important to provide library functions for manipulating file
flag strings if we ever want this interface to be adopted outside
of the source tree, but now isn't necessarily the right moment
with 4.0-release just around the corner.

b3ea3170b3 Fix ftpd core dump when hostname is not set.
When hostname is not set, ftpd core dumps, because there is no
  NULL check for freeing name resolving information for its own
  hostname.
  So the check is added.

e3be4d7b7e sync iruserok() extension API with other BSDs
Some of rcmd related function is need to be updated to
  support IPv6. Some of them are already updated as standard
  document. But there is also several de-facto functions and
  they are not listed in standard documents.
  They are,

    iruserok()  (used by rlogind, rshd)
    ruserok()   (used by kerberos, etc)

  KAME package updated those functions in original way.

    iruserok_af()
    ruserok_af()

  But recently there was discussion on IETF IPng mailing
  list about how to sync those API, and it is decided,

    -Those function is not standard and not documented.
    -But let BSDs sync their API as de-facto.

  And after some discussion, it is announced that

    -add update to iruserok() as iruserok_sa()
    -no ruserok() API change(it is only updated internaly)

So I sync those API before 4.0 is released.
The changes are,
   -prototype changes
   -ruserok() internal update (use iruserok_sa() inside)
   -removal of ruserok_af()
   -change iruserok_af() as static functioin, and also prefix the name with __.
   -add iruserok_sa() (Just call __iruserok_af() inside)
   -adding flag AI_ALL to getipnodebyaddr() called from __icheckhost().
    This is necessary to support IPv4 communication via AF_INET6 socket
    could be correctly authenticated via iruserok_sa()
   -irusreok_af() call is replaced to iruserok_sa() call
    in rlogind, and rshd.

7dbe16fbee When a threads package registers locking methods with dllockinit(),
figure out which shared object(s) contain the the locking methods
and fully bind those objects as if they had been loaded with
LD_BIND_NOW=1.  The goal is to keep the locking methods from
requiring any lazy binding.  Otherwise infinite recursion occurs
in _rtld_bind.

This fixes the infinite recursion problem in the linuxthreads port.

9bfb1dfc29 Revamp the mechanism for enumerating and calling shared objects'
init and fini functions.  Now the code is very careful to hold no
locks when calling these functions.  Thus the dynamic linker cannot
be re-entered with a lock already held.

Remove the tolerance for recursive locking that I added in revision
1.2 of dllockinit.c.  Recursive locking shouldn't happen any more.

Mozilla and JDK users: I'd appreciate confirmation that things still
work right (or at least the same) with these changes.

3600eb76c6 Work around an assert failure in the dynamic linker's default thread
locking functions.  If an application loads a shared object with
dlopen() and the shared object has an init function which requires
lazy binding, then _rtld_bind is called when the thread is already
inside the dynamic linker.  This leads to a recursive acquisition
of the lock, which I was not expecting -- hence the assert failure.

This work-around makes the default locking functions handle recursive
locking.  It is NOT the correct fix -- that should be implemented
at the generic locking level rather than in the default locking
functions.  I will implement the correct fix in a future commit.

Since the dllockinit() interface will likely need to change, warn
about that in both the man page and the header file.

d3980376e8 Add a new function dllockinit() for registering thread locking
functions to be used by the dynamic linker.  This can be called by
threads packages at start-up time.  I will add the call to libc_r
soon.

Also add a default locking method that is used up until dllockinit()
is called.  The default method works by blocking SIGVTALRM, SIGPROF,
and SIGALRM in critical sections.  It is based on the observation
that most user-space threads packages implement thread preemption
with one of these signals (usually SIGVTALRM).

The dynamic linker has never been reentrant, but it became less
reentrant in revision 1.34 of "src/libexec/rtld-elf/rtld.c".
Starting with that revision, multiple threads each doing lazy
binding could interfere with each other.  The usual symptom was
that a symbol was falsely reported as undefined at start-up time.
It was rare but not unseen.  This commit fixes it.

6e2578e4c4 Revert the libcrypt/libmd stuff back to how it was. This should not have
happened as it was working around problems elsewhere (ie: binutils/ld
not doing the right thing according to the ELF design).  libcrypt has
been adjusted to not need the runtime -lmd.  It's still not quite right
(ld is supposed to work damnit) but at least it doesn't impact all the
users of libcrypt in Marcel's cross-build model.

8ef94ce860 Fix bootpd for Alpha.
bptypes.h originally defined int32 to be of type long. This obviously
doesn't work on the Alpha. By defining int32 (and u_int32) in terms of
int32_t (and u_int32_t) it now is what it says it should be.

Two occurrences of 'unsigned int32' have been changed to 'u_int32' for
consistency.

825316056a Make jdk-1.1.8 work again. It turns out that some code inside
libjava peeks into the dynamic linker's private Obj_Entry structures.
My recent changes introduced some new members near the front of
the structures, causing libjava to get the wrong fields.  This commit
moves the new members toward the end of the structure so that the
layout of the portion that is relevant to JDK remains the same as
before.

I will work with the JDK porting team to see if we can come up with
a less fragile way for them to do what they need to do.  I understand
the current approach was necessary in order to work around some
limitations of the dynamic linker.  Maybe it's not necessary any
more.

926ea445fe Revamp the symbol lookup algorithm to cope better with objects
loaded separately by dlopen that have global symbols with identical
names.  Viewing each dlopened object as a DAG which is linked by its
DT_NEEDED entries in the dynamic table, the search order is as
follows:

  * If the referencing object was linked with -Bsymbolic, search it
    internally.
  * Search all dlopened DAGs containing the referencing object.
  * Search all objects loaded at program start up.
  * Search all objects which were dlopened() using the RTLD_GLOBAL
    flag (which is now supported too).

The search terminates as soon as a strong definition is found.
Lacking that, the first weak definition is used.

These rules match those of Solaris, as best I could determine them
from its vague manual pages and the results of experiments I performed.
