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.

Unfortunately this --enable-dbg-util only problem (caused by
_GLIBCXX_DEUBG) resurfaced, perhaps because of new std::string based
logging in sal; adapt all map files to export the unique symbol.
At least with sw_complex test under load, it happened that an ORequestThread
could still process a remote release request while the main thread was already
in exit(3). This was because (a) ThreadPool never joined with the spawned
worker threads (which has been rectified by calling uno_threadpool_dispose(0)
from the final uno_threadpool_destroy), and (b) binaryurp::Bridge called
uno_threadpool_destroy only from its destructor (which could go as late as
exit(3)) instead of from terminate.
Additional clean up:
* Access to Bridge's threadPool_ is now cleanly controlled by mutex_ (even
though that might not be necessary in every case).
* ThreadPool's stopDisposing got renamed to destroy, to make meaning clearer.

this removes dmake completely out of the build for migrated modules
build.pl now assumes modules to be gbuild, unless there is a
prj/dmake file

(This reverts commit 0ba6bd3ddc025666a6d4bb0640bf443728b23bd3.)
The problems worked-around there are no longer observed by me, so they
were hopefully only a temporal problem (the real root cause had never
been found back then). If problems start to pop up again, we'll need
to have another look at this.
Naming convention for gbuild methods:
- "add" is used for stuff that is logically a part of the target
(i.e. not registered at the Module, but defined in the target's makefile)
- "use" is used for stuff that is logically a different target
(i.e. it is registered at the Module, has it's own makefile, may be
in a different module than the target)
...which has the necessary features to support it.
Change a lot of classes to either contain a protected non-virtual dtor
(which is backwards compatible, so even works for cppumaker-generated
UNO headers) or a public virtual one.
cppuhelper/propertysetmixin.hxx still needs to disable the warning, as
the relevant class has a non-virtual dtor but friends, which would still
cause GCC to warn.
Includes a patch for libcmis, intended to be upstreamed.
SAL_UNUSED_PARAMETER (expanding to __attribute__ ((unused)) for GCC)
is used to annotate legitimately unused parameters, so that static
analysis tools can tell legitimately unused parameters from truly
unnecessary ones. To that end, some patches for external modules
are also added, that are only applied when compiling with GCC and
add necessary __attribute__ ((unused)) in headers.
They are virtually unused (at least the LibO code base has only a
single use of UNO_REF_QUERY) but confuse static analysis tools that
classify unused function parameters as "tags" (which legalizes the
unusedness of those parameters) if they are of an enum type with
exactly one value defined.
* New build prerequisite doxygen (controllable via --with-doxygen).
* Adapted various headers to slightly different doxygen documentation
syntax, but much clean up still remains to be done (i.e., warnings
emitted by doxygen fixed).
