libdl: first execute all destructors, then munmap library

Fix problem which might exist since 2011. We need to execute
the destructors for all dependant libraries, before munmap the
shared libraries, otherwise running destructor of a dependent library
might cause a segfault, trying to access an already unmapped memory.

This fixes for example segfaults while running php -m with ldap
module.

libdl: calculate the length for second parameter of munmap.

Revert 35105679b9a900d58dadd0852e679c235f8176ba and add some debug
code.

linuxthreads: implement pthread_condattr_{s,g}etclock()

More applications are using pthread_condattr_setclock()/
pthread_condattr_getclock() in their code. Port these two
functions from NPTL over to be more compatible.

libdl: end must be bigger than start

libdl: remove gcc warnings

libiconv: remove function, which is not available w/o libiconv a4 macros

libdl: fix problem with unmapping

The munmap was still called with broken length, as sometimes
start was empty. This finally solves segfaults when running
php -m with ldap module activated.

libdl: better checking and logging for ctors/dtors

libdl: remove dead code

libdl: remove LDSO_NO_CLEANUP

libdl: cleanup old inline changelog

common/sendfile.c: bugfix can't support offset is NULL

In ltp testcase sendfile08.c, it use offset=NULL to test the api.

PATCH V2:
fixup the stupid missing check in the end. Sorry for lose test.

See "man sendfile" and it really support offset is NULL.

or1k: add F_{DUPFD_CLOEXEC, SETPIPE_SZ, GETPIPE_SZ}

Those definitions exist on all other architectures, but were not
present in or1k specific headers when or1k support was merged.

On the kernel side, their support is completely architecture
independent, so we just need those definitions to make those fcntl()
calls available on or1k.

Otherwise it breaks mips64 n64.
Should be used for aarch64/tilegx only.
