e55019792f Check the access mode in the flags before waiting on a read or a write
that might never be possible if the file was not opened in the corrent
mode. This prevents a hang for bad programs. Why do people code like that?

cccdaf6051 When doing a F_SETFL, read the flags back so that the ones stored
in the file descriptor table are exactly what the kernel knows subject
to the O_NONBLOCK flag being requested by the user.

aa1c40519a This is a null commit to log the fact that I have done a repository
copy to bring these files into libc from libcompat.  I will enable
them and kill off the libcompat versions on the main branch soon.

5728cd1f8f Add a commented out CFLAGS entry that can be uncommented to compile thread
lock debug into libc_r. I don't know if this is the best place to document
this, but at least it is recorded somewhere. 8-)

765df5f4d2 Implement compile time debug support instead of tracking file name and
line number every time a file descriptor is locked.

This looks like a big change but it isn't. It should reduce the size
of libc_r and make it run slightly faster.

5ed1d7e948 Add compile time debug instead of doing this all the time. Reduce the
time that a thread keeps the file descriptor table locked. In particular,
perform malloc/free calls outside the lock and handle the situation
where two threads can race to initialise the table entry for the same
file descriptor.

4d1f252a40 Add support for compile time debug. This is enabled if libc_r is built
with -D_LOCK_DEBUG. This adds the file name and line number to each lock
call and these are stored in the spinlock structure. When using debug
mode, the lock function will check if the thread is trying to lock
something it has already locked. This is not supposed to happen because
the lock will be freed too early.

Without lock debug, libc_r should be smaller and slightly faster.

10b40100e5 POSIX says that pthread_exit() is not allowed to be called from a
cleanup destructor, so trap this case to prevent me from being being
burnt again by applications that try to do this. With this change, an
application (like one using a mis-configured ACE) will exit the process
after displaying a message quoting the POSIX section that the application
has violated.

fa1af3c55b Simplify the handling of thread specific data. Only track if a key
is allocated or not, rather than keeping a count and attempting to
know it it is in-use. POSIX says that once a key is deleted, using the
key again results in undefined behaviour.
