02a93d74e0 Don't compile in the use of poll() when building libc_r. This isn't 
so much a "fix", rather a bandaid to buy time to fix it properly
within the thread engine.

0b99d9d8ac Add poll to the list of hidden syscalls so that it gets renamed. This 
propagates a bug (that there is no poll wrapper in libc_r), but it
prevents GNU configure scripts from trying to use it in preference
to select. libc_r really needs to change it's wait interface to use
poll instead of select because poll is more a superset of select that
the other way around.

This should allow the Roxen web server to work out-of-the-box. It's
configuration intercae is kinda neat. The code isn't. Shiver. 8-)

06ca87e9f7 Update the caller's descriptor masks even if there are none ready for

meaning that THERE ARE *NO* DESCRIPTORS READY.

ff55f42545 Remove components that would duplicate those in libc now that the 
includes and interfaces have been merged with the 8.1.2 update.

This essentially leaves the isc/* files that named and named-xfer use.
It might be best to just compile them with .PATH in both cases rather than
bothering with libbind.

8eb25828ad 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?

627961e45f 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-)

ddc8afd422 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.

a675022188 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.

3411c10600 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.

74ebed9424 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.
