1f4b63f824 Add various utrace's for use with ktrace to the ELF runtime linker. To
activate the traces, set the LD_UTRACE (or LD_32_UTRACE) environment
variable.  This also includes code in kdump(8) to parse the traces.

5fd885b07b Fix the buggy rev. 1.117. dagmembers are only initialized for dlopen'ed
dso that are actually loading. If dso a.so depends on b.so, then dlsym
with handle from dlopen("b.so") will fail unconditionally.

Correct implementation shall use the Obj_Entry.needed list to walk
dependencies DAG.

d0cb0064fe When looking up the symbol by dlsym, look it not only in the object
given as dso handle, but also in the implicit dependencies of that dso.

Also, const-ify the read-only parameter objlist of symlook_list.

that the documented TCB is at the tail of the extended TCB. In other
words, the base of the TCB has a negative offset from the TLS.

e8ea7f0260 1. Attempt to take one bullet out of the foot-shooting gun by silently
ignoring errors when sourcing rc.conf* files. The most common error
occurs when users put a command of some sort into those files.
(ifconfig is a popular choice)

2. Make the file rotation logic simpler by starting one down from
the "top" of the list, rather than at the top.

3. Try to make file rotation more secure by calling unlink(1) on all
new file names before rotating an old file to the new name, rather than
merely calling 'rm -f' on any files that exceed the number of files
to save.

a599a64a9f In the daemon code, check for and report possible errors
from accept(2) and fork(2).  Also close all unneeded fds
in the child process, namely listening sockets for all
address families and the fd initially obtained from accept(2).
(The main ftpd code operates on stdin/stdout anyway as it
has been designed for running from inetd.)

52828c0e9c In preparation for a new malloc implementation:
* Add posix_memalign().

  * Move calloc() from calloc.c to malloc.c.  Add a calloc() implementation in
    rtld-elf in order to make the loader happy (even though calloc() isn't
    used in rtld-elf).

  * Add _malloc_prefork() and _malloc_postfork(), and use them instead of
    directly manipulating __malloc_lock.
