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.

ca0476a680 Add compile time thread lock debug support. 
Add a thread specific flag to trap the case where pthread_exit() is
called from a destructor in violation of the Posix standard.

ffa7278469 Delete the atomic unlock function since it is no longer required. 
Simplify the atomic lock to just write a value of 1 to the lock instead
of taking the value passed by the caller (which just confused things).

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.

09e640d1b3 Add a trivial mechanism for returning a useful default value if one is 
available and the kernel MIB setting is zero.

Return the result from getpagesize() if the p1003_1b.pagesize MIB
value is zero.

Here is a some example for avoiding a confusion.

 It asssumes a logged host domain is "spec.co.jp". All
example is longer than UT_HOSTNAMELEN value.

   1) turbo.tama.spec.co.jp: 192.19.0.2  -> trubo.tama
   2) turbo.tama.foo.co.jp : 192.19.0.2  -> 192.19.0.2

ff9be3e0ff If building and installing libdescrypt, do it first so that the symlinks 
point to it rather than libscrypt.

This was how it was done prior to libscrypt being added in.  This should
stop more people getting burnt with the /usr/lib -> /usr/lib/aout
transition, and the same when the ELF libs come online.
