This improves on b68640c44e "Prevent creation of
new ORequestThreads during shutdown," which added throwing the DisposedException
from ThreadAdmin::add. But ThreadAdmin::m_disposed can only become true via
uno_threadpool_destroy -> ThreadPool::joinWorkers -> ThreadAdmin::join, and
ThreadAdmin::add observing that can only happen via uno_threadpool_putJob ->
ThreadPool::addJob -> ThreadPool::createThread -> ORequestThread::launch ->
ThradAdmin::add, where the bridges should ensure that uno_threadpool_destroy
does not run in parallel with uno_threadpool_putJob. So demote this from a
DisposedException to a SAL_WARN.

Now that we have default values for Exception constructor params,
remove lots of boilerplate code.

This changes all generated API headers (.hpp and .hdl) to use a
namespace alias 'css' instead of the pointlessly long com::sun::star
Makes the change in cppumaker & associated tools, adds a global
namespace alias definition in sal/types.h, and removes a kiloton
of local, now pointless-to-harmful versions of that alias from all
over the code.

This is a follow up to d015384e1d "Fixed
ThreadPool (and dependent ORequestThread) life cycle" that still had some
problems:
* First, if Bridge::terminate was first entered from the reader or writer
thread, it would not join on that thread, so that thread could still be running
during exit.
That has been addressed by giving Bridge::dispose new semantics: It waits until
both Bridge::terminate has completed (even if that was called from a different
thread) and all spawned threads (reader, writer, ORequestThread workers) have
been joined. (This implies that Bridge::dispose must not be called from such a
thread, to avoid deadlock.)
* Second, if Bridge::terminate was first entered from an ORequestThread, the
call to uno_threadpool_dispose(0) to join on all such worker threads could
deadlock.
That has been addressed by making the last call to uno_threadpool_destroy wait
to join on all worker threads, and by calling uno_threadpool_destroy only from
the final Bridge::terminate (from Bridge::dispose), to avoid deadlock. (The
special semantics of uno_threadpool_dispose(0) are no longer needed and have
been removed, as they conflicted with the fix for the third problem below.)
* Third, once uno_threadpool_destroy had called uno_threadpool_dispose(0), the
ThreadAdmin singleton had been disposed, so no new remote bridges could
successfully be created afterwards.
That has been addressed by making ThreadAdmin a member of ThreadPool, and making
(only) those uno_ThreadPool handles with overlapping life spans share one
ThreadPool instance (which thus is no longer a singleton, either).
Additionally, ORequestThread has been made more robust (in the style of
salhelper::Thread) to avoid races.
