        * attr.c, implement.h, pthread.h, ChangeLog: Resolve CVS merge
        conflicts.

        * private.c (_pthread_find_thread_entry): Changes to return type
        to support leaner _pthread_threads_table[] which now only stores
        _pthread_thread_thread_t *.
        (_pthread_new_thread_entry): Internal changes.
        (_pthread_delete_thread_entry): Internal changes to avoid contention.
        Calling routines changed accordingly.

        * pthread.h: Modified cleanup macros to use new generic push and pop.
        Added destructor and atfork stacks to _pthread_threads_thread_t.

        * cleanup.c (_pthread_handler_push, _pthread_handler_pop,
        _pthread_handler_pop_all): Renamed cleanup push and pop routines
        and made generic to handle destructors and atfork handlers as
        well.

        * create.c (_pthread_start_call): New function is a wrapper for
        all new threads. It allows us to do some cleanup when the thread
        returns, ie. that is otherwise only done if the thread is cancelled.

        * exit.c (_pthread_vacuum): New function contains code from
        pthread_exit() that we need in the new _pthread_start_call()
        as well.

        * implement.h: Various additions and minor changes.

        * pthread.h: Various additions and minor changes.
        Change cleanup handler macros to use generic handler push and pop
        functions.

        * attr.c: Minor mods to all functions.
        (is_attr): Implemented missing function.

        * create.c (pthread_create): More clean up.

        * private.c (_pthread_find_thread_entry): Implement.
        (_pthread_delete_thread_entry): Implement.
        (_pthread_new_thread_entry): Implement.
        These functions manipulate the implementations internal thread
        table and are part of general code cleanup and modularisation.
        They replace _pthread_getthreadindex() which was removed.

        * exit.c (pthread_exit): Changed to use the new code above.

        * pthread.h: Add cancelability constants. Update comments.
